A je res potrebno extendat view? Kaj pa če normalno dam sliko za ozadje in potem v aktivnosti preračunavam tape?

public class Background extends View {

	Bitmap bgImage;

	public Background(Context context) {
		super(context);
		bgImage = BitmapFactory.decodeResource(getResources(), R.drawable.bg);
		
	}

	@Override
	protected void onDraw(Canvas canvas) {
		super.onDraw(canvas);
		bgImage = getResizedBitmap(bgImage, canvas.getHeight()-100, canvas.getWidth());
		canvas.drawBitmap(bgImage, 0, canvas.getHeight()/2, null);
		
	}

	public Bitmap getResizedBitmap(Bitmap bm, int newHeight, int newWidth) {
		int width = bm.getWidth();
		int height = bm.getHeight();
		
		float scaleWidth = ((float) newWidth) / width;
		float scaleHeight = ((float) newHeight) / height;
		
		// CREATE A MATRIX FOR THE MANIPULATION
		Matrix matrix = new Matrix();
		// RESIZE THE BIT MAP
		matrix.postScale(scaleWidth, scaleHeight);

		// "RECREATE" THE NEW BITMAP
		Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height,
				matrix, false);
		return resizedBitmap;
	}
}

public class Main extends Activity {

	Background bg;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);

		bg = new Background(this);
		setContentView(bg);

		bg.setOnTouchListener(new OnTouchListener() {

			@Override
			public boolean onTouch(View v, MotionEvent event) {
				if (event.getAction() == MotionEvent.ACTION_DOWN) {

					Toast.makeText(
							getApplicationContext(),
							"Touch coordinates : "
									+ String.valueOf(event.getX()) + ":"
									+ String.valueOf(event.getY()),
							Toast.LENGTH_SHORT).show();
					return true;
				}
				return false;
			}
		});
	}
}
