I want to be able to tell where they \'touch\' the image.

I can easily get the screen coordi

Answer 1

I have just had the same problem, and trying the DeeV solution I always got 0 from both getLeft() and getTop() methods. As changing the layout wasn't an option (because I think that getTop/Left are relative only to the view's parent) I had to figure out how to get the absolute position of the view.

Here is a similar approach using getLocationOnScreen(location):

protected Point getRelativePosition(View v, MotionEvent event) {
    int[] location = new int[2];
    v.getLocationOnScreen(location);
    float screenX = event.getRawX();
    float screenY = event.getRawY();
    float viewX = screenX - location[0];
    float viewY = screenY - location[1];
    return new Point((int) viewX, (int) viewY);
}
