Android :: Dialogs On A Change Orientation

Mar 5, 2010

I'm doing an APP that shows some dialogs. Those dialogs are Alert dialogs, and when they are being showed if I change the orientation of the mobile I lost them...they are not being kept on the screen.

Android :: Dialogs on a change orientation


Android :: Change Background Of Alert Dialogs?

Jun 25, 2010

I use the AlertDialog class in my application. By default, these alert dialogs have a transparent background. I'm trying to use an opaque background instead, very unsuccessfully.

These are my styles:

CODE:....................

I applied the "MyOpaqueActivity" style successfully for whole activities (the window background is changed to "my_background"), but it doesn't work for alert dialogs within those activities. The "alertDialogStyle" attribute and my "MyOpaqueAlertDialog" style don't seem to have any effect.

So how can I change the background of these alert dialogs?

Android :: Orientation Change - Dialog Above Activity With Fixed Orientation

May 14, 2009

I have created an activity for my game which handles all orientation changes by itself and has a fixed "portrait" layout. Actually it uses the accelerometer and is rendered using 2D canvas methods. If the level has been completed I show up a highscore dialog in which the user can enter his name. The dialog is floating above the underlying level screen which gets blurred out nicely. This generally works.

Problem is that the dialog does not get rotated if the orientation of the phone changes. So even if the keyboard is exposed the dialog is shown in portrait mode instead of landscape. I have tried to use an activity with dialog theme instead but the behavior didn't change. After several tries it seems that I have found the reason for this: Once there's an activity with fixed orientation in the activity stack then all subsequent activities keep this orientation, too. They will not react on orientation changes anymore (e.g. if the keyboard gets exposed).

After upgrading to 1.5 SDK the described behavior changed a little bit. Now at subactivities indead react on orientation changes like expected. However, the need to have an opaque background! That means that neither dialogs nor activities with dialog theme will work. Those will stick with the orientation of the underlaying activity. So my workaround is to first start a sub-activity with an opaque black background. This activity then shows my highscore dialog on top. It looks quite okay but I wonder if there's a better solution? Is it possible to show a dialog above a fixed portrait or landscape activity which automatically adapts to orientation changes?

Android :: Change Intent Bundle Data Before Activity Recreated After Orientation Change

Jul 30, 2009

I have a notification that starts my activity and passes a messages using the intent's putExtra() function. The message is then displayed to the user in the activity's onCreate function. When the application is restarted due to a orientation change, the message is shown again as it is still in the intent's bundled data.
How can I remove the extra data?

I tried the following:

Bundle bundle = getIntent().getExtras();
if (bundle.getBoolean("showMessage")) {
// ... show message that is in bundle.getString("message")
// remove message
bundle.remove("showMessage");
}

But the message will still be shown after the orientation changed, seems like the intent used is not the one I changed, but the original one. The only workaround I found is to save the showMessage additionally in onSaveInstanceState(). Is there another way? Or is this the way to go?

Android :: Screen Orientation Change

Oct 8, 2009

I notice when using the emulator that when the screen is flipped, I get a following logcat message:

INFO/WindowManager(589): onOrientationChanged, rotation changed to 1

How can I catch this in the code? I want to know whenever the orientation changes. I assume I have to set a listener, but I can't find an example anywhere.

Android :: Possible Leak In Orientation Change

Jul 1, 2009

My app *sometimes* when orientation change, leaks Activities (getInstanceCount() increases from time to time) and i cannot figure out where references to my Activity or rather Context are kept - tried to use jhat but it couldn't help me much.

what is strange: it doesn't always happen on orientation change, so its even harder to fix.

btw when doing normal app life cycle - start, do something, exit - everything is ok - getInstanceCount() always returns 1.

Android :: OnCreate And Orientation Change

Apr 28, 2010

I have an activity that checks stuffs online when it's created (is the GPS on and if not it asks if the user wants to turn it on).

The problem I'm having is that it is also doing it everytime I change the orientation of the screen.

I've read some comments on onConfigurationChanged() but is there a better way to be sure I'm checking the GPS only when the activity is first created?

Android :: AppWidget Update On Orientation Change

Dec 29, 2009

I am developing a photo frame widget, all works except on an orientation change to landscape mode my appwidget doesn't display correctly as I have it set to portrait dimensions and it is too large for the display. I would like to run some code to resize the image so that everything displays correctly and it uses all the space that I allot. What is the correct way to do this? I can think of 2 methods however both seem inefficient. The first would be to register a broadcast reciever to take orientation changes, however I don't want to redo my appwidget everytime the phone is turned on its side as the majority of the time the homescreen is not showing when the orientation is changed (ie other apps are used, and I don't need my code running in the background). I only need it to run when the home screen is shown. The second would be to setup a service to manage my appwidget but that also seems inefficient to be always running in the background.

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 :: Threads And Screen Orientation Change

Aug 30, 2009

In the following sequence of events:

1. Start a new thread (as a result of a button click - or similar).

2. User changes the screen orientation (causing the Activity that started the thread to be destroyed).

3. Thread finishes, and wants to do some dialog (or any UI) work. However, doing a showDialog, dismissDialog, ... will crash, as the thread it still referring to the old Activity.

This can be solved by updating the data in the thread to refer to the new Activity upon a screen orientation change.

However, couldn't the Android framework just forward any requests from a destroyed activity, to the newly created Activity, saving us developers of handling it ourselves?

Android :: View Size After Orientation Change

Jun 17, 2009

Is the view aware of the orientation change in order to return updated size after a change in orientation? I'm handling the orientation myself (android:configChanges="orientation|keyboardHidden"). Does it means that I have to take into account the orientation state when querying for view.getHeight()? The view returns the same value as before the orientation change. It this the normal behavior or I should "notify" somehow the view to "refresh" its size.

Android :: How To Save State During Orientation Change?

Oct 12, 2010

I was looking at the way Android handles orientation change for my application (I discovered that it restarts the mainactivity on orientation change :| ). I've seen that you can ovveride the method protected void onSaveInstanceState(Bundle outState)to save stuff, then have the in onStart. The problem is that I've my view with custom objects and a listview using a custom adapter... Everything is in a ArrayList of these objects, but I've noticed that you can't put arbitrary objects in the bundle! So how do I save the state?

Android :: Mobile Web App CSS Breaks On Orientation Change

Sep 12, 2010

The CSS for my webapp gets completely misaligned when the mobile device is rotated to landscape (target devices are iphone and android). I tried using the javascript solution explained here in order to get my app to switch between a portrait.css and a landscape.css file on orientation change, but that still didn't work. It even messed up the portrait.css once they were both posted to the live server (although it worked on my local machine).The url for the app is http://mobile.geekstats.com/ Does anyone know how I can fix the landscape css?

Maybe I'm missing something obvious, but how do you handle orientation changes for a Cupcake desktop widget?When it is initially created, the onUpdate method of my AppWidgetProvider calls views.setOnClickPendingIntent(buttonID, pendingIntent) to register for my button events, but when the orientation changes, new buttons are created and I don't have an opportunity to re-register the "onClick" listeners.

Android :: Way To Have View Use Different Layout When Orientation Change Occurs

Oct 2, 2009

is there a way to have a view use a different layout when an orientation change occurs. suppose i want the view to look one way in portrait and another way in landscape. all the same data, but arranged differently.I'm thinking one way to do this would be to have two different linear layouts with android:visibility="gone" and simply display the appropriate one (set android:visibility="visible") based on orientation -- i.e. do this from code.is there a way to do this in xml? or something like this (i.e. in landscape, put the textview here, in portrait, put it here instead)?
