Currently, the SurfaceView that contains the images have a white-background, but if I were to overlay them onto the phone's camera feed, they would have to be transparent. The camera and animation drawing ca...
Hi Everyone, I'm trying to figure out how to work around my problem. I've read http://groups.google.com/group/android-developers/browse_thread/thread/a2aac88a08cb56c2/b7dff4ba388cd664?lnk=gst&q=SurfaceView#b7dff4ba388cd664 which sort of answers my question but as far as I can tell, it's a sort of "tough luck" answer. So here's my pr...
My app fc when activity that's using SurfaceView as content view calls startActivityForResult(...) and activity that has been started calls finish() This does not happen if I change content view to something else than SurfaceView.

I'm making great progress porting my Color Computer Emulator to Android. It works on a Droid 2 with a hardware keyboard but I'm unable to get the virtual keyboard to send KeyEvents to my SurfaceView subclass. I've included the setFocusable(true), setFocusableInTouchMode(true), requestFocus() and requestFocusFromTouch() in the View per su...
Hello, I'm new to Android development and I've been having an issue that I haven't been able to fix. I'm mostly using code from examples provided in the SDK so I'm not sure what's happening here. I'm simply trying to create a custom view GhostSurfaceCameraView that extends SurfaceView. Here's my class definition file GhostSurfaceCameraVi...
Hello, I am currently trying to write a simple shoot them up game with top down perspective. I am using SurfaceView and Canvas to draw the graphics on the screen, but I cannot find out how to make the "camera" scrollable. The player character is always in the center of the screen and the camera(SurfaceView's canvas essentially) is suppo...

I am trying to convert my SurfaceView (camera preview) into a Bitmap for face detection on the fly. I am receiving a not null image but when I display it onto a view it appears to be plain black. Any ideas what might be the reason and how to proceed? (I believe it is difficult but not impossible to extract the bitmap from a SurfaceView ...
I am trying to rotate a canvas with canvas.rotate and move an object on it at the same time. The problem is that with the rotation, the coordinate system of the canvas rotates as well, so I get cases when my object is supposed to be moving along the y axis, but the y axis is rotated on place of the x axis. It is a mess. Is there a way to...

I'm implementing a fairly standard app with the Android sdk that involves drawing using the SurfaceView, SurfaceHolder, Callback setup. In my main thread (UI thread) I have no drawing or handling of the SurfaceHolder (or the canvas you retrieve with it). In a separate thread I have the following: Log.i("GAME.DrawThread", "run()"); ...
The image above is the first page of my game. Normally the big blue 'button' background image should not show up there. I declare my custom background image for my buttons in layout file like this: <Button android:id="@+id/id_button_startgame" android:layout_width="wrap_content" ...

I'm working on an RPG for Android, using the LunarLander API demo. I've already made a game using this demo (Porcupine Assassin, check it out!) so I've got a good grasp of the Canvas class and things of that nature. My problem is, in RPGs you need a way to access inventory, stats, etc. So I've set the BACK button to start the class Inve...

Hi, I've been wondering if canvas has a limit boundary. I mean if I use functions such asdrawline(), drawbitmap(), drawcircle(), does android really draw something on the canvas and waste some CPU cycles?? because after all the drawing functions, the actual picture print on the screen is decided by the screen size. And if I draw on som...
