Hello, I have written a simple application that draws an image (Drawable) on the screen. When the user presses a key, the image is supposed to move. When I first start the application from Eclipse, the keys work fine. However, if I go to another screen in the emulator and then go back to my application (with a long press of the Home button) then the keys don't work any more. The same problem occurs if I go to the applications menu and click on the icon for my application--the key events don't work.
I have included the code for my view below. The only other file in the application is an Activity that has a very simple onCreate method to create an instance of this view and call setContentView(). Thanks, Brian Durney public class DrawView extends View { Bitmap img; Drawable botDraw; float x = 35, y = 100; public DrawView(Context context) { super(context); setFocusable(true); // MIGHT BE NECESSARY FOR KEY EVENTS BitmapFactory.Options opts = new BitmapFactory.Options(); opts.inJustDecodeBounds = true; img = BitmapFactory.decodeResource(context.getResources(), R.drawable.bot2); botDraw = context.getResources().getDrawable (R.drawable.bot1); } public boolean onKeyDown(int keyCode, KeyEvent msg) { switch (keyCode) { case KeyEvent.KEYCODE_W: y -= 5; invalidate(); return true; case KeyEvent.KEYCODE_S: y += 5; invalidate(); return true; default: return super.onKeyDown(keyCode, msg); } } public void onDraw(Canvas canvas) { canvas.drawColor(0xFFC0C090); Paint paint = new Paint(); paint.setColor(Color.GREEN); paint.setAntiAlias(true); canvas.drawCircle(35.0f, 50.0f, 20.0f, paint); canvas.drawBitmap(img, x, y, null); canvas.save(); canvas.rotate(45, 180, 80); // ANGLE IN DEGREES, PIVOT X, PIVOT Y botDraw.setBounds(150, 50, 210, 110); botDraw.draw(canvas); canvas.restore(); } } --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
