Alert password field that stores password into the keychain and checks it against original login view controller

2012-01-20T00:19:00.009-07:00

This is what I would like to happen I have screwed this up 60 times over now.

Ok, I have a login View Controller that handles the login using the username and password and a remember me switch. The login view controller verifies against an API, checks the credentials then proceeds. If the user has selected the remember me switch the password is stored. Next I have a separate deposit view controller. Once the user clicks the deposit button within this deposit controller it pops up an alert with a password field and once the password is entered it checks against the original login screen password to see if they match if they do. It pushes on another view controller and then life goes on. Otherwise if it doesnt match the stored pass and alert with and error is presented.

This just doesnt seem that hard but I'm having the hardest time with it I hope I made myself clear and questions let me know.

error with scrollToRowAtIndexPath

2012-01-20T00:19:00.007-07:00

I am getting an error when using my application that used tableviews, the error looks like this.




2012-01-19 10:19:51.442 bcode[1176:207] *** Terminating app due to uncaught exception 'NSRangeException', reason: '-[UITableView scrollToRowAtIndexPath:atScrollPosition:animated:]: row (3) beyond bounds (3) for section (0).'

terminate called throwing an exception(gdb)

What is happening is that when the user drills down my navigation view they can select a cell from the tableview of each view, which later will be used to build a search string.

However I allow them to go back and change their selection if they made an error.. this error happens when the user changes the value of the parent view then going into the subview only if the previous selection was outside the number of entries in the current tableview..

normally this wouldn't be a big problem however, inside viewDidAppear I am calling a method that scrolls to the previously selected cell... which obviously is what is breaking the app and giving me the error.




- (void)viewDidAppear:(BOOL)animated

{

    [super viewDidAppear:animated];

    //Scroll to previously selected value

    [self.tableView scrollToRowAtIndexPath:oldCheckedIndexPath  atScrollPosition:UITableViewScrollPositionMiddle animated:YES];

}

how can I stop this from executing I have tried about a 100 different if statments in the parent view and the subview catching the new indexpath and checking agains oldselected indexpaths then setting




oldCheckedIndexPath = nil;

however somehow it always manages to mess up anyway.

UIImage Resize without loss of quality

2012-01-20T00:19:00.005-07:00

Im looking for an external library (or a method using Apple frameworks that doesn't destroy the quality) which will let me scale down images.

I have tried this 'simple-image-processing-library' but it only works for black and white - I don't know how to make it work for colour images. ( http://code.google.com/p/simple-iphone-image-processing/ )

I have tried Core Graphics, UIKit, the "trevor" ( http://vocaro.com/trevor/blog/2009/10/12/resize-a-uiimage-the-right-way/ ) method - which makes EXTREMELY blurry images and really I don't know what else I can do - I can't continue programming my app without getting at least half-decent image scaling working. I think interpolation is needed to get decent results.

Given the recent advances in iOS, I really hope someone can help me. This isn't a problem that only I am having, lots of other people seem to have the same problem, so if someone could solve it here, I'm sure if would appreciated by a very wide audience!

Thank you very much

SQLCipher Working But Incorrect Password

2012-01-20T00:19:00.003-07:00

I've just implemented SQLCipher in my app to encrypt one fairly simple database. I followed all of the setup instructions carefully on this tutorial and the project is building and the app is running successfully. However, when I use their sample code to encrypt my database, my password is somehow incorrect and I am now unable to open my database. Here is the code:




NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] 

                      stringByAppendingPathComponent: @"dict.sqlite"];

if (sqlite3_open([path UTF8String], &database) == SQLITE_OK) {

        const char* key = [@"BIGSecret" UTF8String];

        sqlite3_key(database, key, strlen(key));

        if (sqlite3_exec(database, (const char*) "SELECT count(*) FROM sqlite_master;", NULL, NULL, NULL) == SQLITE_OK) {

            // password is correct, or, database has been initialized

            NSLog(@"Correct Password :)");

        } 

        else {

            // incorrect password!

            NSLog(@"Incorrect Password :(");

        }

    }

    else {

        sqlite3_close(database);

        NSAssert1(NO, @"Failed to open database with message '%s'.", sqlite3_errmsg(database));

    }

}

sqlite3 *database; is declared in my interface. My app is crashing on this line:




if (sqlite3_prepare_v2(database, sql, -1, &init_statement, NULL) != SQLITE_OK) {

    NSAssert1(NO, @"Error: failed to prepare statement with message '%s'.", sqlite3_errmsg(database));

}

Everything worked just fine without the encryption, so there is no issue with the rest of my code. The console prints "Incorrect Password :(" before the crash. The crash log is: Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Error: failed to prepare statement with message 'file is encrypted or is not a database'.' There is clearly an issue with the password. Any help?

Thanks.

Flex iOS app version has huge font size?

2012-01-20T00:19:00.001-07:00

I have an Android/iOS app that is almost complete, my only issue is that my iOS version has a huge font size on TextFields, whereas the Android version works perfectly?

Both apps work fine when I'm testing on my computer, but when I test on the devices (iPod 4G and Galaxy S) the Galaxy S displays the font as shown on my computer but the iPod displays the text in huge letters. It's for an input textbox so it's a big deal as you can't even see what you are typing in the letter are so big!!

I'm not sure what the issue is? Is there something I can add/look for to make certain the size? My is primarily coded in AS3 and I've attempted with a CSS file which looks like this:




@font-face{

src: url("fonts/Incognitype.ttf");

fontFamily: IncognitypeEmbedded;

fontWeight: normal;

size: 10;}

Any help would be awesome! Thanks!

Zoom very much and keep a high quality of the image without loading a large image on iPhone

2012-01-20T00:18:00.011-07:00

Does anyone know about some framework or some tutorial to help me develop a feature into an iPhone app which will allow the user to zoom in very much on an image and display high-quality details of the image without loading the large image. Something like Google Maps. You can see an example here: http://www.zoomify.com/

How safely cancel all requests in ASINetworkQueue on view deallocate

2012-01-20T00:18:00.009-07:00

I have ASINetworkQueue with more than 1500 requests in it. Performing this number of requests takes for a while. If user leaves view controller while this queue is running the OS deallocates the view controller and I get "message sent to deallocated instance" error.

I have tried to use




[self.queue cancelAllOperations];

in dealloc method, but seems like it cancels only requests that are waiting in queue, not the request that is currently running and I'm getting the same error.

What is the correct way to handle this situation? Is it possible to make the view controller not to be deallocated while queue is not finished even if user left it? Or is there a way to cancel all requests (including requests that are running) in queue?

How to share a variable between multiple Views/XIBs

2012-01-20T00:18:00.007-07:00

I've read several similar threads, but can't seem to figure this out - sorry. I've got a project with multiple Views, including a ViewController, several "sub" views, and a NavigationController. I'd like to have an array that is accessible from any of the Views, so that I can populate a TableView or a TextField, etc. I'd like the array to be modifiable from any View that can access it.

Right now I have this in the xxAppDelegate.h file:




NSMutableArray *listOfHeadings;

@property (strong,nonatomic) NSMutableArray *listOfHeadings;

And in the xxAppDelegate.m file I populate the array:




listOfHeadings = [[NSMutableArray alloc] init];

[listOfHeadings addObject:@"Heading 0"];

[listOfHeadings addObject:@"Heading 1"];

But I can't seem to access the array from other .m files. How do I do this correctly?

Attempts to tap a UIButton in a UITableViewCell using UI Automation fail with "could not be tapped”

2012-01-20T00:18:00.005-07:00

I have an iPhone app that I'm testing using UI Automation.

I have a button in a UITableViewCell but when I try to tap on it using UI Automation I get the following error.




Script threw an uncaught JavaScript error: target.frontMostApp().mainWindow().scrollViews()[0].elements()[element_name].tableViews()[0].elements().firstWithPredicate(name contains[c] 'Brooklyn').elements()["detailsButton"] could not be tapped

I have enabled accessibility on the button in Interface Builder and assigned the accessibility label (and identifier) "detailsButton". I can retrieve the button element and have verified that it is valid. I just can't tap it for some reason.

The UIButton is a round rectangular button with user interaction enabled. Thanks for any feedback.

iPhone: Notification Center Trouble

2012-01-20T00:17:00.009-07:00

I wrote an app that allows the user to enter data in a UITextField, and one of them allows them to enter in a specific date. I'm trying to have an alert appear in the iPhones Notification Center when the date is 15 hours away, even when the app is not running at all.

EDIT: New code-

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { UILocalNotification *localNotif = [[UILocalNotification alloc] init];




NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

[dateFormatter setDateFormat:@"MMdd"];

NSDate *eventDate=[dateFormatter dateFromString:eventDateField.text];



localNotif.fireDate = [eventDate dateByAddingTimeInterval:-15*60*60];

localNotif.timeZone = [NSTimeZone defaultTimeZone];





localNotif.alertBody = @"Event Tomorrow!";



localNotif.alertAction = @"Show me";



localNotif.soundName = UILocalNotificationDefaultSoundName;

localNotif.applicationIconBadgeNumber = 0;

[[UIApplication sharedApplication]presentLocalNotificationNow:localNotif];

}

What triggers iOS 5.0 cache purge?

2012-01-20T00:17:00.007-07:00

As of iOS 5.0 Apple began to purge or clean the Caches directory inside individual applications when it decided the device was using too much space. Can anyone point me to the location of documentation or anecdotal information regarding at which threshold this cache cleaning occurs (for instance 90%+ disk usage) and how often it is checked?

ShareKit Facebook authorization looping

2012-01-20T00:17:00.005-07:00

I set up ShareKit for iOS 4.3 using the instructions found here.

I implemented the method to call the ActionSheet(see the code below). The Twitter method works correctly, Your asked to authorize the app to tweet on your behalf then your redirect to a view to post the tweet.




- (void)myButtonHandlerAction

{

  SHKItem *item = [SHKItem text:@"ShareKit is Awesome!"];



  // Get the ShareKit action sheet

  SHKActionSheet *actionSheet = [SHKActionSheet actionSheetForItem:item];



  // ShareKit detects top view controller (the one intended to present ShareKit UI) automatically,

  // but sometimes it may not find one. To be safe, set it explicitly

  [SHK setRootViewController:self];



 // Display the action sheet

 [actionSheet showFromToolbar:self.navigationController.toolbar];



}

However when I click the Facebook method takes you to authourize the app but when you return to the app it never shows a post dialog. Am I missing a step?

Resetting UISearchbar programmatically

2012-01-20T00:17:00.001-07:00

Is there a possibility to reset a UISearchbar with searchDisplayController programmatically which is active and already contains text?




- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {



    if (tableView == self.searchDisplayController.searchResultsTableView) {

       searchDisplayController.searchResultsTableView.hidden = YES;

       searchBar.showsCancelButton = NO;

       [searchBar resignFirstResponder];

    }

}

This solution is working, but there is still text in the searchBar. If i add those lines of code:




searchBar.text = @"";

There is always a black transparent view left.

Any solutions?

removeFromSuperview and release memory management

2012-01-20T00:16:00.011-07:00

I have a MBProgressHUD that I allocate as follows:




self.progressHUD_ = [[[MBProgressHUD alloc] initWithView:self.view] autorelease];

if I call removeFromSuperview then would I have to call progressHUD release again? Also if I declare a property with something like this:




NSString * title_;



@property (nonatomic, retain) NSString * title_;

then it is guaranteed that in my dealloc I should have a release on title right?

dismissModalViewControllerAnimated doesn"t return

2012-01-20T00:16:00.009-07:00

If I push a view onto the Navcontroller it works great and I can return from it either with code or using the Nav Controller back button.

Then I change it to present the view modally. The preset works but I cant get it to return and dismiss the modal view.

This works... main view




Tools *screen = [[Tools alloc] initWithNibName:@"Tools" bundle:[NSBundle mainBundle]];



     [mainNavController pushViewController:screen animated:YES];



    [screen release];

One the modal view:




- (IBAction)btnCancel:(id)sender {





  [self.navigationController popToViewController:[self.navigationController.viewControllers  objectAtIndex:0] animated:YES];





}

But then I change it to modal like this on the modal view it does not go back to the main view.




Tools *screen = [[Tools alloc] initWithNibName:@"Tools" bundle:[NSBundle mainBundle]];



 [mainNavController presentModalViewController:screen animated:YES];



  [screen release];

On the modal view:




- (IBAction)btnCancel:(id)sender {





    [self.parentViewController dismissModalViewControllerAnimated:YES];





}

I have tried about everything I can think of, obviously I am missing something! Any ideas?

thanks for any help!!

Switching Between View Controllers Efficiently

2012-01-20T00:16:00.005-07:00

In order to switch between views in my iOS app, I have been using Modal View Controllers. It works fine, but is this bad coding practice? Will it be detrimental to the memory usage of my app?

In response to comments asking for more information, the views I am switching between are normal informational views. I am using three views to navigate through my app:

Main View: Has buttons to navigate to specific informational views

Info View: Has buttons to navigate to specific web pages for information

Web View: Displays information through a UIWebview

I have an improvised navigation bar at the top for navigating "back" and "home" do the main page.

Overall, this is a web app with structure provided with menus in other views. I don't want to reveal what it does specifically (it's my idea), however this should be enough information to work with.

I am currently switching between views like this:




newViewController *newView = [[newViewController alloc] init];

[self presentModalViewController:newView animated:YES];

Based on the answers so far, Modal Views are meant to quickly and temporarily display animations, but I am looking for a more permanent approach.

Is there a better way? Please provide example code with your response. Thank you!

EDIT: I apologize for originally not having enough information. I have posted a lot more information. If you need anything else, please comment.

What javascript event gets fired when ios safari gets called from another app

2012-01-20T00:16:00.003-07:00

I'm working on a mobile website / iPhone app combination. Upon entering the mobile website, I prompt the user to 'go to the app', 'download the app', or 'use mobile website'.

From various entry points to the mobile website, I'm mostly worried about verification emails and text messages, so the user will check email, follow the verification link, enter Safari, get prompted to 'go to the app' and the verification link is sent to the app for it to handle.

Now in the same session, if the user gets another email regarding the app, the user will check email again, follow a different verification link to Safari, and I want the 'go to the app' to work the same with the new link.

Some quirks are that upon entering the mobile website, the verification link is stored and the URL is switched to site.com/home. The iphone overlay is completely separate from the rest of the site and doesn't have access to the site's storage of the verification link so the event needs to fire as soon as the site loads. This works when first loading the page, but upon re-entering the second time, I need to listen to event that triggers as soon as ios Safari re-enters. I've tried listening to "pageshow" but by that time, the URL is already site.com/home.

Thanks

Subclassing UISearchDisplayController For Abstraction

2012-01-20T00:16:00.001-07:00

I have multiple UIViewController that have table views. I want these VCs to just handle UI stuff as they will all search the same database. I want to subclass UISearchDisplayController so I can have this subclass handle all the data and search stuff.

The VC I am working with is a UIViewController with a UITableView and a UISearchDisplayController . I have it set and can check to display the initial, or the searched data into the table view by using if/else statements like: if (tableView == self.searchDisplayController.searchResultsTableView) % else...

I want this custom subclass that I'm creating to handle the code that is executed in the self.searchDisplayController.searchResultsTableView statement so I can have some abstraction and can use this custom class with other VCs.

Any ideas on how to continue with this? I think I need to override some methods in the UISearchDisplayController .

EDIT:

Actually I may be coming into this wrong. I have it stepup the way I like right now, but there is no abstraction, so I can't really reuse this code in other parts of the app. My IB is setup like this:

How to display 2 different classes (activities) in a fragment in ANDROID?

2012-01-20T00:15:00.005-07:00

I have an already working android app, but I need to update it for better layout on tablets. I can rewrite it no-problem, but what I want to ask is;

I will have 2 fragments on screen (one for list, and one for details). When I select a customer from list, details will update itself (I have already done this without a problem). BUT, when I select an item from details fragment, it must change itself (it must be opened on details fragment, but of course it will be a different class). For example first details will be a list of details, but when I select an item from details list, it will be a different layout, maybe WebView or so..

To better represent the idea,




LLLLLL DDDDDDDDDDDDDDDDDDDDDDDDDD

LLLLLL DDDDDDDDDDDDDDDDDDDDDDDDDD

LLLLLL DDDDDDDDDDDDDDDDDDDDDDDDDD

LLLLLL DDDDDDDDDDDDDDDDDDDDDDDDDD

LLLLLL DDDDDDDDDDDDDDDDDDDDDDDDDD

LLLLLL DDDDDDDDDDDDDDDDDDDDDDDDDD

Where "L" is list fragment, and "D" is details fragment. But I want to show 2 (or more) different classes (activities) (Not at the same time btw) in the details fragment. How do I do that? I was searching this for 2 full days, there is nice tutorials but I couldn't find any example for this behaviour.

Thanks in advance.

Designing animation for android application

2012-01-20T00:15:00.001-07:00

What is the best way to design and embed an animation into an android app. (I'm not talking about transitions and activities in/out animations.)

I can think of 2 ways of doing it:

designing the animation with flash or something similar, export png-sequence with transparent bgs and creating an animation from the images in an xml file (How do I write this kind of xml?)

creating a grid of images with all the frames of the animation that I've created and save it into one image. than using something like background-position in css in order to move the visible area of the image on each frame enter (By Java code, or by xml)

which of this is better/most common? and how do I implement the solution (if there is a better solution - that would be great). and what programs do you usually use for this kind of task

(the goal is to achieve something that works like the frog in cut the rope or the birds in angry birds for example)

thanks!

Handheld iPhone Android Specific CSS not working at all

2012-01-20T00:14:00.011-07:00

I am trying to create specific CSS for handheld devices, and I feel like I've tried every way possible with no effect.

The reason I need to do this is so that handheld devices to not use fancybox but instead open the link in a new tab.

To do this in the div there are 2 UL's, each with a class (screen & handheld).

I want the handheld ul to be hidden on desktops and the screen ul to be hidden on handhelds which should be working using display: none on each.

To get the device specific CSS to work I've tried using seperate css files in the HTML header such as:




<link rel="stylesheet" type="text/css" media="screen" href="css/master.css" />

<link rel="stylesheet" type="text/css" media="handheld" href="css/handheld.css" />

or, within the master.css file:




@media only screen and (max-device-width: 640px) {

    .screen { display: none !important; }

    }

but this does not work. Android always seems to use the UL that includes the fancybox class and thus loads up fancybox every time.

I've tried it in multiple Android browsers (Opera, stock and Dolphin).

Any ideas would be much appreciated!

Thanks

Barcode scanner application which sends result to a PHP application [closed]

2012-01-20T00:14:00.007-07:00

I'm not sure that this is the right place to ask this, but I'm going to give it a try. I'm looking for an application that can read a barcode and then send the code to another application. The second application is a PHP one, an e-commerce website. The first application, the one that reads the code, can also be an iOS or Android application, I don't mind.

Long story short I need an application that scans a barcode and then sends the result to a PHP application.

Did any of you happen to use something like this before?

Thank you.

            <category android:name="android.intent.category.LAUNCHER" />

        </intent-filter>

    </activity>

</application>

The problem is, that when I'm installing apk file, there is no activity shown, because, as I understood system can't specify what activity should be shown.

I just really need two activities shown in launcher, so please don't give advice about removing intent-filters from second activity, or if you do so provide me another way to show two icons in launcher.

Thanks in advance.

Android: Selector isn"t working as expected in TableRow selection

2012-01-20T00:14:00.003-07:00

I have a TAbleLayout in my XML with 1 row i.e. te headings row. Other all rows, I add dynamically. I want to make a row selected on clicking it & on touching it. I added clickListener to each row and am able to trap click event. But when the mouse is pressed or kept pressed, I see color change, then again it comes to normal color. I want the color to stay changed until I click other row or click somewhere else to deactivate the selected row.

My selector XML code :




<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android"> 

<!--  Active state -->  

<item android:state_selected="true" android:state_focused="false"

      android:state_pressed="false" android:drawable="@android:color/transparent" />      

<!--  Inactive state-->  

<item android:state_selected="false" android:state_focused="false"

      android:state_pressed="false" android:drawable="@android:color/transparent" /> 

 <!--  Pressed state --> 

 <item android:state_pressed="true" android:drawable="@color/yellow" />



<!--  Selected state (using d-pad) -->  

 <item android:state_focused="true" android:state_selected="true"

       android:state_pressed="false" android:drawable="@color/yellow" />

My Java code where I generate rows dynamically :




private void createView(TableRow tr, TextView tv, String data, int rowId) {

    tv.setText(data);



    tv.setTextColor(Color.WHITE);

    tv.setPadding(20, 0, 0, 0);



    tr.setPadding(0, 1, 0, 1);

    //tr.setBackgroundColor(Color.TRANSPARENT);

    tr.setBackgroundDrawable(this.getResources().getDrawable(R.drawable.tablerowselector));

    tr.setId(rowId);

    tr.setClickable(true);

    tr.setFocusable(true); // Added thinking that if its not focusable then it can't be selected, but makes no difference

    tr.setOnClickListener(this);

    tr.addView(tv);

}

If I handle in clickListener event, and set Background color of row based on setting prevRowSelected and currRowSelected logic, that works. But how to make selector work and why it is not working ? Can't selector work the way am trying to achieve it ?

Thanks

Any help is appreciated.

ISBN barcode search using eclipse/android

2012-01-20T00:13:00.011-07:00

I know it is possible to scan a movie and see if the movie is available at the store. How would I do this using zxing? I did look over the links pertaining this and I am having a difficulty time understanding it all. I did download the .apk file and convert it to .zip, but I do not see any classes in the folders. I am really confused and I wish there was a web site that explains how to use zxing to make this possible.

anyone have any web sites they know of that will get me started?

thanks.

Android - Ad agency that pay for impression [closed]

2012-01-20T00:13:00.009-07:00

I was wondering what is the best Ad Agency that pays for every 1000 impressions.

I have recently released my new app (Tic Tac Toe Go) and have been using AdMob, however I recently found out that they do not pay for impressions and clicks only.

I would like to change this and was wondering what is the best ad agency to go for, ideally one which has a good fill rate and pays out on impressions.

Thanks in advance, Raj

Header always shows in android-pulltorefresh when customize

2012-01-20T00:13:00.005-07:00

I was trying to customize android-pulltorefresh library developed by Johan Nilson. I wanna use my own adapter rather than a String array. I was able to complete almost every thing but the pull to refresh header is always visible. (see the image) I want it to visible only when I pull the listview like it does with the demo app. I compared my code with the demo but I couldn't find any difference between them which effect layout.

Thanks in advance !

android fragments edittext button focus

2012-01-20T00:13:00.003-07:00

being new to android app development, I encounter a problem regarding the interaction of android fragments, edittexts, focus and buttons.

I have one fragment activity with several tabs. Most tabs have one fragment each. But in one tab, I have a ListFragment and a fragment with edittexts and buttons, which I call edit fragment. When the user selects a list item, the content of the edit fragment is shown in the current tab. When trying to edit a text there, more precisely, when hitting a different key than the backspace key, the new char is not shown, but the first button below gets the focus. Why? And how can I avoid this behavior?

Earlier, I had a different activity for the edit fragment and the editing worked perfectly. But for other reasons and because it is recommended, I have only one activity now. Thank you for help!

            </intent-filter>

        </receiver>

    </application>

All i want to do is to 'toast' the Number i'm calling (or when i get called).

Isn't it working that way? Its the only code i use at the moment. Just one Broadcastreceiver running in the background and fired with a phone-event.

Thanks, prexx

XML layout overlapping AlertDialog"s Title

2012-01-20T00:09:00.003-07:00

I am developing an Android application where the user is asked to "setup" before recording data. This is accomplished using an AlertDialog that inflates an XML layout, using such code:




final AlertDialog.Builder builder = new AlertDialog.Builder(this);



LayoutInflater vi = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

View v = vi.inflate(R.layout.setup, null);



builder.setView(v);

On an emulator or a 2.3.3 device, it looks fine:

However, the title that reads "Configure Options" is overlapped on a 2.1.1 device (which has a smaller screen). It looks more or less like this:

Does anyone know what the potential problem may be? The XML layout is scroll enabled so that if it doesn't fit in the dialog, the user can scroll (which works fine in the emulator and 2.3.3, but not 2.1.1). Perhaps there is some way to make the AlertDialog fit the whole screen using Java code? Thank you for the help.

Android: Prevent GPS from stopping

2012-01-20T00:09:00.001-07:00

I have an issue with the GPS on Android. I am using the onStatusChanged(int status) with the GPSListener to read the status of the GPS. However, I notice that after some point, the GPS stops since the status returns:

GpsStatus.GPS_EVENT_STOPPED

How can I prevent the GPS from stopping at all? (Eventually I will stop it manually, but having it on when needed is very crucial)

Determine width and height of a bitmap

2012-01-20T00:07:00.005-07:00

I am using the following code snippet to create a bitmap with text.




Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG); 

paint.setStyle(Style.FILL);

paint.setColor(fontColor);

paint.setTextSize(fontSize);

canvas.drawText("My Text", x, y, paint);

Here's the catch. How do I determine the size of the Bitmap to use in the canvas beforehand? For instance if I want a bitmap with "Hello World!" on it, I want to find the width and height of it even before I draw the text on the canvas.

onRestore not invoked for my custom BackupAgent

2012-01-20T00:07:00.001-07:00

There are some data in my Android app that I would like to backup and restore. For that purpose I have created a custom implementation of BackupAgent.

In my manifest in have included the backup agent as you can see below




<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    android:installLocation="auto"

    package="com.myapp"

    android:versionCode="14"

    android:versionName="1.13" >



    <application

        android:backupAgent="com.myapp.MyBackupAgent">



        <meta-data

            android:name="com.google.android.backup.api_key"

            android:value="my key" />

I have included the backup service api key, although I am testing with the emulator (Android 2.2) and it should not be necessary, because it uses the local backup transport.

In order to do the test of the backup and restore I have done the following:

Start the emulator with my application installed.

Enable backup

adb shell bmgr enable true

Call the part of my code were the dataChanged method in the BackupManager class is called.

Initiate manually the backup operation

adb shell bmgr run

Checked in the log that the onBackup method of my custom BackupAgent was called.

Uninstall the app

Reinstall the app

Check in the log if the onRestore method is called.

The thing is that the onRestore method does not seem to be called and I don't know why. After reinstalling the app or manually triggering the restore with adb I see the following in the console.




$adb shell bmgr restore com.myapp

restoreStarting: 2 packages

restoreFinished: 0

done

and this other in the log

V/LocalTransport(   59): finishRestore()

D/AndroidRuntime( 8259): Shutting down VM

but I don't see that the call to onRestore is actually made (I have some logging statements just at the beginning of it?

Has this ever happen to you? Is there any reason by the onRestore method is not called, even in the onBackup was called?

Thanks for your help!

Android phonegap app : unable to retrieve an image taken by the camera using my own code (not phonegap"s)

2012-01-18T21:53:00.011-07:00

Note- even though im using phonegap, the question is not about some issue in that.

Hi, im developing a android app. my app is using phonegap 1.3.

mi problem...

Im using phonegap apis to take a picture and display it in my app. But whats happening is due to some reason the os kills my app after the camera is launched, so that after the photo is clicked, my app is relaunched and it doesnt get the info abt the taken picture.

As a workaround to this problem ( the problem ), i designed a phonegap plugin which on app start checks if the app had crashed while taking a picture (some flags in code), and if it is restarting after crash, it retrieves the Pic.jpg taken by the camera and tries to displays it. The problem is that its not able to get the right image, or even a proper .jpg file for that matter.

mi code...

Phonegap makes an intent to start the camera and passes the uri for the Pic.jpg that it creates into that intent which it passes to startActivityForResult.




Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");

File photo = new File(DirectoryManager.getTempDirectoryPath(ctx),  "Pic.jpg");

intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));

this.imageUri = Uri.fromFile(photo);

this.ctx.startActivityForResult((Plugin) this, intent, 0);

Note- The above code is from the file CameraLauncher.java of Phonegap.

Now, im assuming that the startActivityForResult stores the picture the user captures at the file which was created by 'photo' in the above code. So even if after the os closes the app while the camera is open (refer - the problem ) the photo will be stored there. PLEASE correct me if this assumption is wrong, or if the photo might be being saved somewhere else.

So taking into account this assumption i wrote a plugin which retrieves this image using the same logic which Phonegap uses in CameraLauncher.java




Uri imageUri;

ExifHelper exif = new ExifHelper();

exif.createInFile(getTempDirectoryPath(ctx) + "/Pic.jpg");

exif.readExifData();

File photo = new File(getTempDirectoryPath(ctx),  "Pic.jpg");

imageUri = Uri.fromFile(photo);



Bitmap bitmap = null;



bitmap = android.provider.MediaStore.Images.Media.getBitmap(this.ctx.getContentResolver(), imageUri);





ContentValues values = new ContentValues();

values.put(android.provider.MediaStore.Images.Media.MIME_TYPE, "image/jpeg");

Uri uri = null;

try {

     uri = this.ctx.getContentResolver().insert(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

} catch (UnsupportedOperationException e) {

     uri = this.ctx.getContentResolver().insert(android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI, values);

}



// Add compressed version of captured image to returned media store Uri



OutputStream os = this.ctx.getContentResolver().openOutputStream(uri);

bitmap.compress(Bitmap.CompressFormat.JPEG, 20, os);

os.close();



exif.createOutFile(getRealPathFromURI(uri, this.ctx));

exif.writeExifData();



bitmap.recycle();

bitmap = null;

System.gc();

result = new PluginResult(Status.OK, uri.toString());

This is roughly the same logic as Phonegap uses. (I've removed all exception handling n all for posting. So assume there are no compile errors n all.) So, im basically trying to retrieve the Pic.jpg and return it to my phonegap app.

BUT whats happening is that im getting a corrupted file of abt 150kb that isn't even a jpg (doesnt open).

Please tell me if its even possible to retrieve images in this manner after the activity that started the camera as died. And if its possible then, what am i doing wrong. Please help!

Create a Mobile Agent using Jade for Android

2012-01-18T21:53:00.009-07:00

I first heard of JADE around 4 months back. Recently, I stumbled upon a link that confirmed the release of JADE for Android . I have gone through the various JADE tutorials for creating agents.

However, I don't know how to go about creating a mobile agent for the Android platform. Can anyone who has worked with JADE in Android, tell me how should I create a simple mobile agent for the Android platform?

Any tutorials , links would be appreciated.

Thanks in advance

Android auto installation

2012-01-18T21:53:00.007-07:00

We want to install our application on to (thousands of)phones and these phones will be later delivered to clients. Do we have to do this manually? Is there a faster way to do this?

For example, in Windows Mobile, if you put your installation files in a certain folder on SD card and when you insert that SD card to the phone the app is installed automatically to the device. Any similar mechanism on Android?

Thanks in advance.

Android app widget with dynamic text rows

2012-01-18T21:53:00.005-07:00

How to implement such an app widget?

User can select how many data rows to show through the widget configuration. The problem is that on different devices TextViews have different sizes and the widget itself has different sizes too. Even when device orientation changes the widget change its size too. So I don't know how to determine how many text rows fit the widget in current conditions and how to put a text in a bottom of the widget.

What event Asus Transformer calls in Android, then docking or undocking the tablet?

2012-01-18T21:53:00.001-07:00

I have problems with my app on Asus Transformer TF101, with keyboard.

If i dock it to keyboard (or undock it) during displaying a activity, the activity is recreated. That means: onDestroy is called. onCreate is called.

Is it possible to catch the event that user is undocking or docking?

I would like to show a warning message, save the data and finish the activity..

Problem background: In my case, it changes the data in edittext fields, then user undocks or docks. I have created a tablelayout with edittexts fields, like editable datagrid. On Asus it messes up, then undocking, the system recreates the activity and all data in datagrid is rewritten automagically. All rows become like the last row. I assume that system does the redraw by ID's, but i have inflated the rows into datagrid, so the edit fields in rows have same ID's.

How can I make a RadioButton with overlapping text?

2012-01-18T21:52:00.007-07:00

I'm adding programmatically multiple answers to a questions as RadioButtons in a RadioGroup (see code and image below).

I almost achieved it but instead of having a radio button with a text on its side (see image below), I would like to have only the text and the background.

Can I get rid of the radio button?

Or can I set my current background as the radio button (with checked/unchecked states), and add a text overlapping it?




RadioGroup answer_container = (RadioGroup) findViewById(R.id.answer_container);



while (c.isAfterLast() == false) {



    RadioButton answer = new RadioButton(PCItem.this);

    answer.setText(c.getString(c.getColumnIndex(DBAdapter.KEY_ANS_TEXT)));

    answer.setBackgroundResource(R.drawable.btn_ans);

    answer.setPadding((int)(30 * density), 0, 0, 0);

    answer.setGravity(Gravity.CENTER_VERTICAL);

    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams((int)(775 * density), (int)(81 * density));

    params.setMargins(0, (int)(20*density), 0, 0);

    answer.setLayoutParams(params);



    answer_container.addView(answer);



    c.moveToNext();

}

Custom Font, No Support for setFakeBold/TextSkewX

2012-01-18T21:52:00.005-07:00

We use a TextView with a custom font. There are a lot of Spans with normal ASCII letters mixed with our custom symbols. Some text are bold or italic.

text##aaa (# - our special symbol from Unicode Private Area. Fallback is correct.)

Everything works fine. We just override the font in UpdateDrawState.




private void ApplyTypeFace(TextPaint ds)

{

    ds.UnderlineText = false;



    ds.FakeBoldText = m_bBold;

    if (m_bItalic)

        ds.TextSkewX = -0.25f;

    else

        ds.TextSkewX = 0;



    if (m_bFrColorSet)

        ds.Color = m_frColor;

    if (m_bBgColorSet)

        ds.BgColor = m_bgColor;



    ds.SetTypeface(m_fnt);

Today a customer with Bejing WowPad with Android 2.1 reported an issue.

setFakeBoldText(true) misses the ASCII (fallback from default font). No ASCII characters are shown . setTextSkewX(-0.25) is ignored.

Can I check the support of these features?

Android BroadCastReceiver refresh all activities

2012-01-18T21:52:00.003-07:00

I have an issue using BroadCastreceiver to refresh activities in my application. I'm using a service which is doing some calculations and in onDestroy() method I'm doing this :




@Override

public void onDestroy(){        

    super.onDestroy();



    Intent intent = new Intent("finish");

    this.sendBroadcast(intent);

}

and in my activities I'm doing this :




receiver = new BroadcastReceiver() {

        public void onReceive(Context context, Intent intent) {

            if(intent.getAction().equals("finish")) {

                getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);



                 TabGroupActivity parentActivity = (TabGroupActivity)getParent();

                 Intent previewMessage = new Intent(Tutorial.this, Tutorial.class);

                 parentActivity.startChildActivity("Tutorial", previewMessage);



                 progressBar.setVisibility(View.GONE);

                 sync.setImageResource(R.drawable.sync_icon2);



                 final SharedPreferences isLogged = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());

                 SharedPreferences.Editor editor = isLogged.edit();

                 editor.putBoolean("getProgBar", false);

                 editor.commit();

            }               

        }

    };

    registerReceiver(receiver, new IntentFilter("finish"));

I have that function in all my activities and the problem is that if I change 2-3 of them before my service stop, after that I can see in my LogCat logs from other activities which has that function too, but I'm not currently on these activities. They are just somewhere in activity stack. But the thing that I can't understand is it reloading them (even if I can't see it visually) and how to prevent this kind of issues. I need to refresh only activity which I'm in.

Thanks!

ThreadPoolExecutor for running AbortableHttpRequest - how to call abort?

2012-01-18T21:52:00.001-07:00

I'm running a networking service in android where I direct all my http requests to run and get callbacks from the service when the requests are complete. I run the requests in a ThreadPoolExecutor to limit the number of concurrent requests. As the requests run within the pool, they eventually create an HttpGet or HttpPost, both of which indirectly implement AbortableHttpRequest , which allows one to cancel the connection (say, if it's blocking for a long time).

If a user cancels a request, I'd like to somehow drill into the thread queue and call the abort routine for that request. If, for example, a web site is not responding and the user chooses to do something else, right now my only option is to wait for the standard 5 minute http timeout to occur for that hung request before that thread is freed up. If I could access the thread that has my request and call abort, that would free things up right away.

From what I can understand, it appears once my request has gone into the thread pool, it's a black box until it comes out the other end. Querying the queue will only hand back futures, which hides the runnable.

Is there a better approach for this? I'm fairly new to java and threading (I mostly do perl, which doesn't do threads very well at all).

image won"t show in tableView

2012-01-18T21:51:00.011-07:00

I'm creating a tableView in appcelerator (Android) and I want to add an image to it. This is just a test because I also had some problems with it in my project and I wanted to try it out first somewhere else so I wouldn't ruin my whole project.

I first added the standard png's to see if he would show those, and he did. But when I add a png that I've created, he refuses to show it in the tableView. Does someone know why he refuses to show the image? (I created that png in photoshop by changing one of the standard png's and adding my image to it.)




var win = Titanium.UI.createWindow({

    title:'tableViewRow',

    backgroundColor:'#fff'

});



var regData = [

{leftImage:'KS_nav_ui.png', title:'gft', left:20, color:'black'},

{rightImage:'KS_nav_views.png', title:'grofvuil', left:20, color:'black'},

{leftImage:'glas.png', title:'glas', left:20, color:'black'}

];



var tbl = Titanium.UI.createTableView({

    data:regData

});



win.add(tbl);

win.open();

Here's an image of the result I get in my android emulator (android api: Google APIs Android 2.2 and screen:HVGA)

popen on android NDK

2012-01-18T21:51:00.009-07:00

Is popen not supported by android NDK?

I read this page and wondering if this is true

The same is possible with POSIX popen() but it is not currently supported by bionic, so you can't use that in Android JNI. Instead you can probably use the system() and pipe the output to a file and then read that file afterwards. Looks like the Java approach will be cleaner if you will be doing the rendering in Java.

But I also read someone suggesting to use popen. I also tried it myself but sometime my app crashes and I dont know why.

Is popen safe to use in android ndk?

Android - Get preference from activity to broadcast receiver

2012-01-18T21:51:00.007-07:00

I'm developing an Android app but I have a problem. When I try to get a saved preference from my Activity and use it in a BroadcastReceiver , it tells me that string I'm looking for doesn't exist.

This is how I save the preference in the Activity:




private void SavePreferences(String key, String value) {                         

  SharedPreferences sharedPreferences = getPreferences(MODE_PRIVATE);

  SharedPreferences.Editor editor = sharedPreferences.edit();

  editor.putString(key, value);

  editor.commit();

}

And this is how I try to get the preference in BroadcastReceiver :




String pref = PreferenceManager.getDefaultSharedPreferences(context)

  .getString("MEM1", "Does not exist");

Where MEM1 is the string I saved before.

My problem is that when I read pref , I'm getting the default value of Does not exist , instead of my preference value ( MEM1 ). Can someone point me to where I'm going wrong?

REST webservice with Android client vs RPC

2012-01-18T21:51:00.005-07:00

We are still trying to decide between implementing a REST webservice vs going with RPC. Googles eclipse plugin makes it very easy to create an RPC service which is what the main attraction is for the RPC way. However, a REST service would seem to be easier to modify, IMHO, and would also allow for a future iOS client to connect with little or no rework. One concern I would have and maybe this is a problem with RPC also or indeed any Client-Server model is how do you modify your existing service and allow old clients to still work while allowing new clients to use the new functionality. What I mean is can you point me towards any thing we should look out for when modifying a web service so as not to break existing clients or force them to upgrade. Any links you have that would cover this would be appreciated

Is there any alternative for GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT)?

2012-01-18T21:51:00.003-07:00

I get a fill rate of about 30fps in my application. I know that GLES20.glClear() is used to clear the screen for every draw. If i comment it i get a fps of about 60fps. But the output is not as expected. I have a content to be redrawn for the whole screen in every frame. Is there any alternative where i can redraw the whole screen with out using the GLES20.glClear(). Please let me know if there is any way to play around with GLES20.glClear() to improve the performance?

Why do some AlertDialogs disappear upon device rotation?

2012-01-18T21:51:00.001-07:00

When I change device orientation, if AlertDialog was shown, it disappears. This is true for all but one dialogs in my app, and I can't figure out neither what's so special about the one that doesn't disappear nor how to counteract this behaviour. Any possibility to preserve dialogs upon orientation change (except for manual management)?

2012-01-18T21:50:00.009-07:00

i have created an application in jquery and google maps javascript v3 , in which i am displaying a user's current location after a button click.

Now the problem is some times i got pretty fine current location and sometimes at the same place its showing my current location miles away but again when i refresh the page i again got the pretty fine current location.

jQuery doesn"t .load() until .ajax() within callback of .load() is complete?

2012-01-18T21:50:00.005-07:00

My problem is that the <div> with the jQuery progress bar ( dnc_scrubber.html ) isn't loaded until all of the other requests are complete.

Is there anyway around this? I want to change the content of #tabs-1 to the progress bar, and animate it while dnc_scrubber.php is doing its work.

The lines.php and progress.php files are used to calculate the percentage of work done by dnc_scrubber.php - which updates the session as it goes along. lines.php and files.php return the session variable.




$('#tabs-1').load('dnc_scrubber.html', function() {

    var querystring = 'col=' + col + '&' + makeQS(files);

    var lines = 0;



    $('#progressbar').progressbar();



    $.ajax({

        url: 'dnc_scrubber.php',

        type: 'POST',

        async: true,

        data: querystring,

        complete: function() {

            for (i = 0; i < files.length; i++) {

                $('#complete').append('<a href="process/MATCHED - ' + files[i] + '">MATCHED - ' + files[i] + '</a><br />');

                $('#complete').append('<a href="process/SCRUBBED - ' + files[i] + '">SCRUBBED - ' + files[i] + '</a><br />');

            }

        }

    });



    $.ajax({

        url: 'lines.php',

        async: true,

        dataType: 'json',

        complete: function(json) {

            lines = json.total;

        }

    });





    function setProgress() {

        if (prog < lines) {

            prog = getProgress();

            $('#progressbar').progressbar('option', 'value', prog);

            setTimeout(setProgress(), 1000)

        } else {

            $('#progressbar').progressbar('option', 'value', 100);

        }

    }



    var prog = getProgress();

    setTimeout(setProgress(), 1000);

});

I have already tried loading the progress bar within the callback function of a .ajax() request with async set to false . The same result happens - the progress bar is not loaded into #tabs-1 until dnc_scrubber.php is complete.

What can I do?

Uncaught type error : Cannot read value "name" of undefined

    for(var j=0;j<2;j++){

            var generatedProductDisplay = '';



            generatedProductDisplay = '<div id="'+productJSON[a].id+'" class="productDiv"><a class="productLink" href="#"><center><div class="productImage"><img src="'+productJSON[a].image+'" width="100%" height="200px" alt="'+productJSON[a].name+'"></div><div><p class="productName">'+productJSON[a].name+'</p></div></center></a></div>';



            pagedisplay = pagedisplay+generatedProductDisplay;

            a++;

        }

        pagedisplay = pagedisplay+'<br/>';

        $(".productDisplay").append(pagedisplay);

    }   



$(".productDiv").live("click",function(){

Setting the id of a link based on it"s href

2012-01-18T21:49:00.013-07:00




$('.portfolioThumbs ul li a').mouseover(

    function(){

        var buttLink = $(this).attr('href') 

        var buttLinkArray = buttLink.split( '/' ); // Split the URL after each / and Create an array of each

        var pFN = buttLinkArray[2]; // We want the Portfolio Folder Name

        var url = window.location.pathname;



        $('.galleryNav ul li a').removeClass('hovered');

        $('.galleryNav ul li a' + '#' + pFN).addClass('hovered');

        window.location.pathname = url + '#' + pFN;

    }       

);

This code allows me to set an ID on each button based on its href when the user "mouseover's" it. Does anyone know how this can be done automatically when the page loads, so that each button in the list gets and ID based on it's href, without any user interaction.

Thanks,

Dan

How to get notification similar to facebook or any other simple form in asp.net

Reload page out of iframe

2012-01-18T21:49:00.009-07:00

I'm using Fancybox and Zend. Hope the following is clear.

On www.example.com/template/edit/id/3 I have jQuery UI Tabs. They are reachable directly via anchors. E.g. www.example.com/template/edit/id/3#tabs-2

On #tabs-2 I have some elements, doesn't matter what it is exactly. You can create or edit them. This elements got a own controller, so for editing them you call /elements/edit/id/44. Currently, I'm doing that in a Layer with Fancybox. I'm using the Iframe functionality of Fancybox for that.

So, if you are on /template/edit and you click on the edit button of an element, a layer opens which includes an iframe which loads /elements/edit.

So, if you change the element now and click on save, i want the layer to automatically close and reload.

Fancybox provides an option to specify what it should do when it gets closed. At the moment i got it like that:




'onClosed'          :  function() {window.location.reload();}

This actually reloads the top window and not the iframe. Also, there's a possibility to close Fancybox via JS. I'm doing that by setting a View Variable which triggers this, e.g:




<?php if($this->close): ?>

    <script type="text/javascript">

    parent.$.fancybox.close();

    </script>

<?php endif ?>

So, if the saving was successfully I set $this->view->close = true and the layer gets clsoed which triggers my JS.

This works fine. My Problem now is to do the reloading with having #tabs-2 in my url.

Of course i could get the urls, clean it up from other anchors the user my typed in etc. and build my url which i set to the window's location, but somehow i think, there must be an easier solution.

E.g. setting the url of the browser to #tabs-2 without reloading, but this also sounds not very nice. The reloading is easy but having the anchor there is quite tricky.

The json encode did not return response after calling the function of fb post to wall

2012-01-18T21:49:00.007-07:00

I have a link which posted data to another page vote.php through jquery.

When I click on that link, it return the state according to the condition. If that user posted the vote before then it displayed the "already voted" other wise "Your vote posted".

All was working fine.

I am using the facebook post to wall sdk.

Now when I call the fb_publish_on_wall function from the vote.php, the message successfully posted to my fb wall but it did not return the state of the vote like "Your vote posted".

What is the problem. When I comment out that line where I am calling the fb_publish_on_wall function then It works fine.

I think the jquery did not get response from vote.php after calling the fb_publish_on_wall function.

How will I fix this?

UPDATED: Here is the fb_publish_on_wall function




function fb_publish_on_wall($message,$link,$picture,$name,$description,$user_facebook2)

{

    $message = str_replace(array('<br />', '<br>'), "\n", $message);

        $description = str_replace(array('<br />', '<br>'), "\n", $description);

        $name = str_replace(array('<br />', '<br>'),"\n", $name);

        $link = str_replace(array('<br />', '<br>'), "\n", $link);



        global $facebook;



                $publishStream = $facebook->api("/$user_facebook2/feed", 'post', array(

                    'message' => "$message", 

                    'link'    => "$link",

                    'picture' => "$picture",

                    'name'    => "$name",

                    'description'=> "$description"

                    ));



        print $user_facebook2;







}

UPDATED: vote.php. This file is big. SO I am only displaying the that two lines from vote.php




echo json_encode(array("state"=>"<span style='color:#8DA326'>".l("Your vote posted").".</span>"));



    fb_publish_on_wall($message,$link,$picture,$name,$description,$user_facebook2);

                 {duration:500}

             );

I had no luck with it, so I tried to code my own function, that changes the vertical background position of an element. It looks like:




$.fn.moveBackgroundY = function( pixels, duration, easing ) {



    return this.animate(

                { pixels: pixels },

                {

                    step: function(now,fx) {



                        console.log("Background Y position - " + now);



                        $(this).css({

                            backgroundPosition: '0px ' + now + 'px',

                        });

                    },

                    duration: duration,

                    complete: function() {

                        $(this).css({

                            backgroundPosition: '0px 0px',

                        });

                    }

                }, easing);

};

To animate the element's Y background position to -900, I call the function like this:




$('#content').moveBackgroundY(-900, 2100, 'easeInOutCubic');

Notice that here the variable now (background position Y) inside step: will will decrease from 0 to -900.

That works fine, but here comes my problem. After this, I need to reset this background position to "0px 0px" directly with the jQuery .css() function, and then animate it again like:




$('#content').moveBackgroundY(300, 2100, 'easeInOutCubic');

In this case, as I reseted my background position to "0px 0px", the parameter now should go from 0 to 300, but it goes from -900 to 300, where -900 was the value I set first calling my function.

Anyone knows what is wrong, or how could I reset this parameter so as It takes the correct values each time?

I have another function like it that rotates the element changing the CSS3 property transform - rotate, and I have the same problem.

Thanks for your help!

Multiple object selection with jQuery

2012-01-18T21:48:00.013-07:00

I have a pretty basic jQuery question and forgive me if it has already been answered. Basically I attempt to have a link slide down a div. This is fairly simple however I require multiple links sliding down their respective divs. I understand I can just name the links and divs unique classes and solve the problem that way, however this naturally also requires a duplication of the jQuery code for each link-div and i have a lot. I therefore need a general script. A simplified version of my situation is as follows:

HTML:




<div>

    <a id=link1>toggle text 1</a>

    <div class=link1>TEXT 1</div>



    <a id=link2>toggle text 2</a>

    <div class=link2>TEXT 2</div>

</div>

My attempt at a jQuery general script for this:




$(document).ready(function() {

    $('[id^=link]').bind('click', function() {

        var $div = $(this).attr('id');

        if($('[class=' + div + ']').is(':visible')) {

            $('[class=' + div + ']').slideUp();

        } else {

            $('[class=' + div + ']').slideDown();

        }



        return false;

    });

});

But as one might expect since I'm writing here it does not work. I am thinking is has to do with the ^= but I can't figure out how to improve it.

Any thoughts?

Best Regards

Andreas

How to use the javascript call method in jQuery?

2012-01-18T21:48:00.009-07:00

Is it possible to use the call method of javascript (as described in the [mdn documentation]) in order to pass the argument this ?

Having for example this code:




console.log(this);

$('#image_id').load(function () {

    console.log(this);

});

I want that the second this (the one included in the load function ) refers to the same as the first one.

I've tried with




console.log(this);

$('#image_id').load.call(this, function () {

    console.log(this);

});

But it doesn't work.

Thank you all in advance for any suggestion.

Is there a jQuery time/calendar plugin for manipulating dates?

2012-01-18T21:48:00.007-07:00

I need to work with dates, adding/subtracting hours and days. With the JavaScript date object this is a bit difficult, since there is only get/set and no add method.

Is there a plugin that ease this work, with a functions like add("2d3h") (add 2 days and 3 hours)?

How to Freeze Pane/Fix Website Header and Horizontal Nav Bar

2012-01-18T21:48:00.005-07:00

I currently have a banner/header as well as a horizontal navigation menu below this header that I would like to freeze pane/fix, so that any content below this header/nav just scrolls beneath it, always.

FYI, need it to work in IE8.

I have setup the following skeleton structure of this as follows:




<div id="banner-nav">

      <div id="banner">

        <div id="nav">

        </div>

      </div>

    </div>



    <div id="content">

    </div>

Would appreciate your help on this. If it cannot be done on the above fashion, any other alternatives that would accomplish my requirement, would be great.

Thanks.

JSF2.0 - InputTextArea inside Dialog cannot be retrieved via Jquery during the dialog"s onShow event

2012-01-18T21:48:00.003-07:00

I have the following dialog inside my .xhtml page.




<p:dialog widgetVar="exampleDialog" onShow="fillTextArea()" >

    <p:tabView id="tabView">

        <p:tab id="exampleTab" title="Example">

            <p:inputTextarea id="someInputTextArea" autoResize="false"

                value="" />

        </p:tab>

    </p:tabView>

</p:dialog>

The dialog is shown when a button is clicked. The fillTextArea javascript function is defined inside script tags at the head of the document.




function fillTextArea() {

    console.log(jQuery("textarea[id='someInputTextArea']")); // logs empty array []

    console.log($("[id='someInputTextArea']")); // logs empty array []

    jQuery("textarea[id='someInputTextArea']").val('xxx'); // does nothing

}

What's the problem? Why can't I retrieve the input text area?

Instead of using the onShow event of the Dialog , I tried:




exampleDialog.show();

fillTextArea();

just in case. But this didn't work neither. I'm trying to set the contents of the inputTextArea .

Any help appreciated. Thanks.

jQuery watermark plugin disappearing

2012-01-18T21:47:00.013-07:00

I am in search for a good jQuery watermark plugin that work with ASP.NET and found here and downloaded it and included in the head portion




<script src="js/jquery.watermark.min.js" type="text/javascript"></script>

I have login and signup on same page and referencing them as:




<script type="text/javascript">

        $(function () {

            $("#<%= (Login1.FindControl("UserName")).ClientID %>").watermark("Enter your Username");

            $("#<%= (Login1.FindControl("Password")).ClientID %>").watermark("Enter your Password");

            $("#<%= (CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("UserName")).ClientID %>").watermark("Enter your Username");

            $("#<%= (CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("Password")).ClientID %>").watermark("Enter your Password");

            $("#<%= (CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("ConfirmPassword")).ClientID %>").watermark("Enter your ConfirmPassword");

            $("#<%= (CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("Email")).ClientID %>").watermark("Enter your Email");

        });

    </script>

Now the problem is the watermark is showing very well for all the textboxes.If I try to login then the page will be doing postback then all the watermark from the textboxes disappears .

So what do I need to do in order not to remove all of them even though there is a postback.

Saving Div Content As Image On Server

2012-01-18T21:47:00.011-07:00

I have been learning a bit of jQuery and .Net in VB. I have created a product customize tool of sorts that basically layers up divs and add's text, images etc on top of a tshirt.

I'm stuck on an important stage!

I need to be able to convert the content of the div that wraps all these divs of text and images to one flat image taking into account any CSS that has been applied to it also.

I have heard of things that I could use to screen capture the content of a browser on the server which could be possible for low res thumbs etc, but it sounds a little troublesome! and it would really be nice to create an image of high res.

I have also heard to converting the html to html5 canvas then writing that out... but looks too complicated for me to fathom and browser support is an issue.

Is this possible in .NET?

Perhaps something with javascript could be done?

Any help or guidance in the correct direction would be appreciated!

EDIT:

I'm thinking perhaps I could do with two solutions for this. Ideally I would end up with a normal res jpg/png etc for displaying on the website, But also a print ready high res file would be very desirable as well.

PostScript Printer - I have heard of it but I'm struggling to find a good resource to understand it for a beginner (especially with wiki black out). Perhaps I could create a html page from my div content and send it to print to a EPS file. Anyone know any good tutorials for this?

cross origin domain

2012-01-18T21:47:00.009-07:00

I am trying to access a PHP file which is located in my domain but I want to do that using AJAX with jQuer. I am using a localhost and from there I am trying to call the PHP file here is the code I am using :




<script>

      $(function() {



        $("#callAjax").click(function() {

            var theName = $.trim($("#theName").val());



            if(theName.length > 0)

            {

                $.ajax({

                  type: "POST",

                  url: "http://studiofutbol.com.ec/upload_file.php",

                  data: ({name: theName}),

                  cache: false,

                  dataType: "text",

                  success: onSuccess

                });

            }

        });



        $("#resultLog").ajaxError(function(event, request, settings, exception) {

          $("#resultLog").html("Error Calling: " + settings.url + "<br />HTPP Code: " +     request.status);

        });



        function onSuccess(data)

        {

            $("#resultLog").html("Result: " + data);



                $('#people_list').append("hola");

                $('#people_list').listview('ref resh');

        }



    });

</script>

But I get this error:

XMLHttpRequest cannot load http://studiofutbol.com.ec/upload_file.php . Origin http://localhost is not allowed by Access-Control-Allow-Origin.

How can I solve this?

How can I drop a cloned image using jQuery?

jQ autocomplete issue in androdi app

2012-01-18T21:47:00.005-07:00

I struggle with the autopcomplete Plugin for jQuery.




<input type="text" id="name" />

<input type="password" id=""pass" />

 //...

$('#name').autocomplete({source: userName});

It works all fine but when I've selected a user name I get a text focus an both the name and the password input field. As soon as I type in a char it appears in both but just in the next moment the courser jumps in the name field and continues writing in there.

I tried to disable and/or unfocus the password field using jQuery's focus/focusout events as well as autcomplete's autocompleteclose events but none of these worked.

My target is a phinegap honegap 1.2.0. app, jQuery 1.18.16 and jqm 1.0 for 2.0+ android.

Edit

I forget the most important observation. This behaviour only occurs when I select a suggestion which is displayed over the password field. So my assumption is the click/tap event will be fired for both events. autocomplete's list and the field. So somewhat it's "transparent" for android.

Solved - Edit jQuery Mobile nested-list - Event

2012-01-18T21:47:00.003-07:00

I'm trying to add a clicked elements into a jquery mobile nested list. I'm having no problem adding the item but I'm having problem changing the text and url on the item (link).

I can see the correct list about 0,5 seconds before it refreshes and everything is the same.

What event can I use to edit a list-item after being listed?

I've tried to run the code from firebug console and everything works , see code below:




var test = $('.ui-page-active .ui-listview > li > div > div a').first().text();     

    var data = $('body').data('mobilMenu');

    var url = $(data).find('a').filter(function() {

        return $(this).text() === test;

    }).attr('href');





    $('.ui-page-active .ui-listview > li > div > div a').first().text(test +" - hovedside");

    $('.ui-page-active .ui-listview > li > div > div a').first().attr("href", url);

This solves the problem




$( "[data-role='page']" ).live( 'pagehide',function(event, ui){

. had the wrong selector
