Android :: Runtime Language Change Support

Mar 8, 2010

I am developing an Android App which communicated with a server. User can select a language of his choice at startup or during the App execution lifetime. After selecting the language, the corresponding XML file is downloaded from server according to language which will map the "Values" of Application strings according to that language. Can I do something like replacing the default Strings.xml which contains English names(Say by default) to the language selected by user. Better will be adding an XML file per language and referring it runtime directly.

Android :: Prevent Orientation Change At Runtime

Apr 15, 2010

Well, preventing an orientation change is easy. But what about doing it at run time.

Say, I have an activity which supports orientation change in normal situations. It has say three Edit Texts.

There's also a button, which when clicked would do some processing in a thread while showing a ProgressDialog which is not cancellable.

Ok, so till the user hits the Button, I want the activity to be able to adapt the orientation changes. I have two layouts files for each orientation with different layout schemes.

What I want is this. Once the user clicks on the button, and the ProgressDialog is showing, I don't want the activity now to be re- created again when the orientation changes. So, before showing the ProgressDialog, is there any way to tell the Activity not to handle Orientation change?

Also, once the process is complete, and the ProgressDialog is removed, I want the Activity again to be able to handle orientation changes.

Android :: Change LinearLayout Layout At Runtime

Aug 25, 2010

I want the ability to re-arrange Views in a LinearLayout, without specifying specific pixel locations, at runtime. for my proof of concept, I have a layout with 2 TextViews, one red, and one black. The red TextView is on the left. I want onClick to set it to be on the right, without adjusting margins, as if I'd re-written the XML of the layout, with the red TextView second.

Android : Change The Height Of A Webview On Runtime

Feb 26, 2010

I have a webview and a table containing 4 buttons. I have set the height of the webview to 400px, so that the buttons are displayed at the bottom of the screen, in portrait mode. My problem is, when changed to landscape mode the buttons are not visible. So I need to change the height of the webview on runtime, when orientation is changed. Do anybody know how to achieve this? I am able to capture the orientation change, using 'onConfigurationChanged' function.

Android :: Change Background Image Of Dialog Or View In Runtime?

Aug 9, 2010

I have a card game I created in android and it is possible to show the scores at any given time by clicking a menu option. I would like that scores dialog to show a different background image when it's loaded depending on factors like who's leading, etc. In my constructor, I have the following relevant code:

public ScoresDialog(Context context) {
super(context);

this.setTitle(R.string.scoresDialogHeading);
setContentView(R.layout.scores_view);
...
}

I have tried getting that view to change it in the showDialog method i wrote like so: findViewById(R.layout.scores_view).setBackgroundColor(Color.BLUE); However, I got a NPE... I tried moving this statement to the onStart method, thinking that the view is not yet initialized but got the same error... Any thoughts on what the right way to do something like that is?

Android :: How To Change Colors Of A Drawable?

Aug 21, 2009

I'm working on an android application, and I have a drawable that I'm loading up from a source image.On this image, I'd like to convert all of the white pixels to a different color, say blue, and then cache the resultant Drawable object so I can use it later.So for example say I have a 20x20 PNG file that has a white circle in the middle, and that everything outside the circle is transparent.What's the best way to turn that white circle blue and cache the results? Does the answer change if I want to use that source image to create several new Drawables (say blue, red, green, orange, etc)?I'm guessing that I'll want to use a ColorMatrix in some way, but I'm not sure how.

Android :: What's Best Way To Handle An Task Progress Dialog On Orientation Change?

May 27, 2009

I have an app that communicates with a server.While it is communicating, it shows a progress dialog.The way this actually works is that I have a class that I call my Network Gateway.Each method takes a Handler as a callback so that the gateway can send back the response as a bundle when it has finished. Right now when someone changes orientation while a network operation is occuring, the activity doesn't know that a thread is running the network code and then the callback might be invalid.What's the right way to do this? I want to make it so that after the orientation switch, the activity can check something to see if a network operation is running and if so, display the progress dialog again and wait for the callback, or set itself as the callback handler now, invalidating the old one.My first guess is that this is exactly the kind of thing services were designed for, but I'd like specifics if anyone can supply them.

Android :: Background Task / Progress Dialog / Orientation Change / Any 100% Working Solution?

Sep 29, 2010

I download some data from internet in background thread (I use AsyncTask) and display a progress dialog while downlaoding. Orientation changes, Activity is restarted and then my AsyncTask is completed.I want to dismiss the progess dialog and start a new Activity. But calling dismissDialog sometimes throws an exception (probably because the Activity was destroyed and new Activity hasn't been started yet).What is the best way to handle this kind of problem (updating UI from background thread that works even if user changes orientation)? Did someone from Google provide some "official solution"?
