I would like to know what the best way would be to draw a background image (this would be pretty much static) and a foreground object which would move depending on user input in Android?
Sort of like a side-scroller game (when the foregroudn object needs to animate and change a lot more than the background).

I am unsure of the jargon so please bear with me, I am seeking advice on the best way to go about drawing the graphics for an app I am developing. Imagine you are creating a game of checkers, where you can drag/drop one piece at a time to a blank space on the board. When the piece is being moved, it seems to me that you should not need to redraw all of the pieces that are not being moved. Using the LunarLander example, is there a way to store the background image and only draw the piece being moved over it? I have been trying to figure out a way to capture the canvas as an bitmap that is occasionally refreshed.

Is there any way to launch an activity w/ Intents (in this case the Browser) in the background, and then bring it to the foreground using a service or activity?
I know it's possible to bring apps to the foreground by launching an intent with FLAG_ACTIVITY_BROUGHT_TO_FRONT
But is it possible to initially launch the activity in the background?
In my application i wait on socket for network events.On some events i have to bring activity into foreground(make activity as running) if at all it is not in the foreground.
View 17 Replies View RelatedIt would appear on a G1 (with the latest software update) that onUpdate () runs even when the widget is not visible. Is there a way of sensing that the widget is or is not visible or is otherwise in foreground? That is, running the code below shows a logcat message at whatever interval the Widget is scheduled to update, whether it's in foreground or not, whether even the screen is dim or otherwise in deep sleep. It would seem onUpdate should only be scheduled to run when the Widget is in the foreground or visible. Is this a defect in the G1, or is there some other API call to detect if the Widget is visible?

I have a subclass of android.app.Dialog and because I am using a light theme, the dialog title comes out as Black on a dark background which is hardly readable. This leads me to the question: how do I change the Dialog title background or foreground colors? Can I do this via a theme? Which property will it map to?

I have used basic AlphaAnimation provided in android framework but found that its slowing down other animations. So i extended a class from SurfaceView and created a thread to update it. ( Again here, i am manipulating alpha of the image ).

View 1 Replies View RelatedI am wondering if there is a way to draw an image, or edit simple lines in a text box. The entire screen is a textView/ect and i would like to be able to write a sentence then draw an image and write again. By draw i think i would use the Canvas, so basically is there a way to include a canvas in a text view?
Evernote does do this, but to edit an image/draw you need to open another app "Skitch", my goal is to try and do this without any extra apps.
For example:
Hello

The structure of some of my activities is a simple ListView with a custom CursorAdapter. The cursor is created in onCreate() on the activity from a SQLite database. The problem is that querying the SQLite database can be quite slow at times with lots of data (and let's assume I've already optimized the sql query as much as possible). Because it occurs in onCreate() on the UI thread, I get ugly black screens when opening the activity, which sometimes turn into ANRs, on a slow phone like the G1. I want to load the cursor in a background and show "Loading.." on screen while doing so. I saw AsyncQueryHandler used extensively in the framework, but this seems a solution geared more towards Content Providers and not application-local SQLite databases. I then thought of trying to load the cursor in a background thread, but realize that this might be problematic, as the CursorAdapter should be instantiated in onCreate() and should take a cursor as a parameter. The latest thought I had was to instantiate an empty MatrixCursor in onCreate() and pass that to the cursor adapter, while kicking off a thread/TimerTask to query the database. Then, on database cursor load, call cursorAdapter.change Cursor to the properly filled cursor. This doesn't seem very elegant and seems quite wasteful, however.
