Android : Change Android Theme At Runtime?
Dec 3, 2009
I am now working on changing android theme style at runtime,when the user select a theme resource,not only the current application,but also all the applications installed on the phone should be changed.For example,just like you change the system language in setting activity,then all the applications' language changed.I just can not figure out how android framework achieves this,anybody knows something about this?
While I tried to use PackageManager,just like this:
PackageManager manager = getPackageManager();
List<ApplicationInfo> apps = manager
.getInstalledApplications(PackageManager.GET_META_DATA);
for (ApplicationInfo app : apps) {
app.theme=android.R.style.Theme_Light_NoTitleBar_Fullscreen;}
It won't work.Does the attribure "theme" in ApplicationInfo read-only?

Is there a way that after install a app, user can have the option to change the app name through a configuration page in that app? Where are all app names saved in the system?

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.

Is it possible to have a user choose how an app should respond to orientation changes? I have it set to android:screenOrientation="sensor" in the manifest but I would like users to be able to turn this on and off or set landscape or portrait orientation permanently.

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.

For an application I need to place some objects at the exact position that I want to have them and therefore I need to use AbsoluteLayout this time.
I want to add buttons dynamically exactly like in the following XML - but during runtime.
CODE:................
How can I archive this? I tried it with the following code to add a button, but I haven't found a function so far to set layout_x and layout_y. How can I do this?
CODE:....................

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.

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.

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?

I'm changing the theme of an activity in onCreate using setTheme (I'm doing that even before calling super.onCreate(), as this is supposed to be more reliable).It does work in the sense that it changes the background and foreground colors. However, my layout has a few elements that use styles like textAppearanceLarge. Now Android's textAppearanceLarge internally uses the textPrimaryColor - which is still unchanged by my theme.I tried to override the primary text color in my theme, but that doesn't seem to work.

I just picked up the phone yesterday and love many things about it however I do not like the look of the UI at all, it looks very amateurish and "cheap". I know there are many themes available out there but do they work on this phone? Does it require a custom ROM? I assume it needs to be rooted to get a custom theme, right? I want something that will change the look of every screen...dial pad, text messages, menus, settings. Imam really not liking the white text on black background.

I want to have a "change theme" feature in ma app. If I call setTheme() in onCreate(), there is one problem.
The moment after I launch my app, a plain white background appears for a second (because I have set light theme in the manifest). After that, the complete layout of my Activity is displayed - it is either with white or black background, according to user's theme preference.
Is there any way I can change whether white or black background appears after launch?

1) I am developing my app in Eclipse 3.4.1 with Android (ver 1.1_r1) plugin. My app compiles and executes without errors when using the Eclipse IDE.
However, when I export my app (unsigned) using Eclipse (via {select project} >right-click>Android tools>export unsigned application package), sign it, and try to run it on the Emulator, it throws a runtime error when I try to update my sqlite database, at which time the specific error created is: SQLite error#14, unable to open database. It is able to read from the database without problems. (I have also verified that the database is: open, is not readonly, is not locked by another thread, is not in the middle of a transaction.)
I have limited experience, but this seems more like a "system" problem given that the app works OK in Eclipse IDE but then fails as an exported/signed apk. Some googling of SQLite resources revealed a similar error on a non-Android platform which was fixed by: "Set your permissions correctly on /var/tmp, or whatever directory you are using to hold temporary files".
Does Android have temporary files, and if so how does it handle permissions on temporary files? Is there a way to check or set these permissions to see if this fixes my problem here?
2) Not sure if it is related, but after I have run the exported/signed app which causes the runtime error, if I reboot the Emulator, and try to run the program using the Eclipse IDE , the program fails with the same exact error. PLUS I also noticed the following error message while the program is installing/running: 03-01 22:22:29.282: ERROR/PackageManager(53): Package com.northwestradiology has mismatched uid: 0 on disk, 10019 in settings; read messages:
I can restore the Eclipse version of my program to be able to execute without runtime errors by utilizing the -wipe-data option for the emulator. But note that if I run my signed APK using an emulator created with the -wipe-data option, it still throws the runtime error listed above...

I want to change my theme. However, I want to change ALL themes, so this includes everything about the phone. What I mean is:
- HomeScreen
- Settings
- Dialog Boxes / Buttons
- Messaging
- Contacts / Phone
- etc.
I have GoLauncher EX, GoSMS, GoContacts downloaded on my phone. But I've yet to find something that I can use as replacement for the Settings screen as well as how to change the Dialog boxes button colors, toggle switch colors, etc.
I'm running Xperia P on ICS.

I'm trying to create a basic AlertDialog using an activity with a theme of Theme.Dialog.What I want is for there to be a horizontal bar between the title and the message. However, the bar is not being resized correctly. Rather than being the width of the activity, the bar is the width of the message text. This means that if the activity is being expanded by the message, then the bar will fill the whole activity, so it looks correct. However, if the message width is less than the activity width, the bar only displays above the part of the activity with the text. I've tried every single combination of "fill_parent" and "wrap_content" that I can think of, and none of those work.I've also tried using RelativeLayout and placing the bar above the message text, but that also doesn't work. If I use the RelativeLayout approach and set the bar to fill_parent, it causes the activity to expand to fill the whole screen width, which is also undesirable. Ideally, I want the text placed, the activity width computed, and the bar resized to that width (without affecting it). Is there some way to flag a view to fill the parent view but not to affect its size?

I use themes in my apps, which generally just extend android:Theme and then set a bunch of styles. I use dialogs made from layouts, but since I set the theme for the application, they have inherited all of the regular styles and no longer carry a border, etc. My question is: How do I say, "I want everything to use this theme which extends Theme, except dialogs, which should use this other theme that extends Theme.Dialog"? It seems like that's how things work by default but when you set the theme to your own, you lose the dialog theme!

I've extended Theme.Dialog to use a different color as per the sample in the ApiDemos project but for some reason it does not use the theme properly in my project. I created a new project and it works perfectly fine there. The main problem here is that it does not show as floating in my project. Instead, it sets the rest of the screen black except for what would be the dialog window, where it uses the correct colors, etc. Any ideas? I am beating my head against the wall here.
