I have been searching forever and have not found a way to create a horizontal progress bar at runtime (I don't want to use XML). How can I set this XML attribute, as seen in this post http://groups.google.com/group/android-beginners/browse_thread/thread..., programmatically?

I have created a activity and set a the title bar to contain a progress bar like this: this.requestWindowFeature(Window.FEATURE_PROGRESS);getWindow().setFeatureInt(Window.FEATURE_PROGRESS, 500);But it turns out to be a horizontal bar, how can I make this a spin bar? (without creating a custom title bar)

View 1 Replies View RelatedI am working on horizontal menu that will open on top of the screen.
Layout is something like following,
|| < || Menu Item1 || Menu Item2 || Menu Item3 || > ||
I want to put this on top of the screen. It can have more than 3 menu item and it can traverse through previous and next arrow.
I started with like this:
RelativeLayout ( width - fill_parent)
Gallery View ( Here i appended adapter )
There is two problem:
- Gallery view contains the space before and after
- While scrolling its item gets selected
How can i build custom component like this ?
I'm currently creating a side-scroller style game for my final year project for my degree.
I'm just wondering how you make the menu designed for when the phone is in horizontal orientation display, even when the phone is held in it's vertical orientation?
i.e. I want the user to know that the game has to be played with the phone in it's horizontal orientation and want the menu's to only display in the horizontal orientation.
I'm attempting to create a list view in Android that shows clickable items that wrap horizontally much like the "To" field in the OS X and iPhone's Mail programs. They have a horizontal list of names that wrap vertically and each name is a separate object, the list is not just a single string. My questions are: Is there a way to do this with a ListView or some other type of AdapterView? Everything I've seen and experimented with is either horizontal scrolling or vertically stacking, but not horizontal wrapping. Are you aware of an existing app with available source that has a view like this that I could look at as an example? The Google Mail/SMS apps just has a single string in the too field that isn't clickable.
View 2 Replies View RelatedIs it possible to create a horizontal LinearLayout where we specify how wide percentage-wise each element is? Something like:
LinearLayout ll = new LinearLayout(); ll.add(new TextView("a")); ll.setViewWidthAtIndex(0, 30); ll.add(new TextView("b")); ll.setViewWidthAtIIndex(1, 50); ll.add(new TextView("c")); ll.setViewWidthAtIndex(2, 20);
I have an xml layout that will display a grid made up of textviews within tablerows. The textview names are cell00, cell01, etc. At runtime, my program will determine which cell needs to be changed.
Is there a way get format a name so that it can be passed to the findViewById method at runtime? For example, if cell00 is needed, how can I generate the parm in this code?
TextView currcell = (TextView) findViewById(R.id.cell00)
Something like "cell"+00 doesn't compile because the findViewById method doesn't accept a String type. I don't want have every textview name in the grid hardcoded in the program - there must be a better way.
Android News & Weather app lets you swipe to reveal another view, just like the iPhone. Can someone show me an example of how this is done? It is not a ViewFlipper attached to a GestureDetector.
View 1 Replies View RelatedI plan to create a runtime for hosting (inner) JavaScript apps using Cordova.
1. There should be a host app acting as the runtime. In this Host-App, it should able to load JS/Html Apps dynamically. Same goes for removing.
2. Also, the inner JS/Html Apps should be able to communicate with each other.
Important is
- that the loaded JS/Html should call native functions like contact list (thats why Cordova should be used)
- and the JS/Html is not necessarily on the device when the apk is created. Hence, it should be able to download the sources and show them in the native app.
I would like to show a modal progress "wheel" overlay on my view.

But to no avail (i.e. still looks the same as without the ...setBackgroundDrawable code).

View 1 Replies View Related1) 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...

View 1 Replies View RelatedI'm just getting started with developing for Android. I'm looking to port one of my iPhone applications, but I'm kind of at a loss for how to draw a view at runtime (a view not declared in the XML). Basically, I want to draw a simple rectangle, but then be able to manipulate its frame after being drawn. Sorry if this is a really, really simple question, but I can't seem to find some equivalent to the iPhone SDK here.

View 5 Replies View RelatedAs an additional anti-pirating strategy, I'd like to compute a checksum on my application at runtime. Since my app communicates with a back-end server, I can send the checksum with each message and the server can deny service to altered apps.

View 15 Replies View RelatedIs it possible to load my main.xml layout file in onCreate() and then later in the app, switch to a new XML layout? I've tried placing setContentView() later on in the app but that seems to not actually set the new View because my references to objects in the newly set xml layout file are returning as null. I've tried doing some layout inflating using the LayoutInflater but I'm having no luck (I'm probably doing something wrong)... So is there any other way to swap layout xml layouts at runtime?

View 8 Replies View RelatedI have a large (900kb) asset in the assets directory which is only used once by the app at initialization time. Is there way for me to delete this file at runtime? If not delete change it's contents to "0" and effectively reduce its size to almost nothing. There isn't really any point of having this take space on the phone's limited memory.
I am writing an application that will run on 2.0 and above. Now, I am thinking of adding the Data backup feature to the application. Is there anyway to modify the manifest file to include the metadata only if the phone is using Froyo(2.2). Ideally, i would like to avoid creating a separate application for just Froyo.
