How to get coordinates of points in an image.

imageViewTouch.setSingleTapListener(new ImageViewTouch.OnImageViewTouchSingleTapListener() {
@OverRide
public void onSingleTapConfirmed() {
x = String.valueOf(imageViewTouch.getY());
y = String.valueOf(imageViewTouch.getX());
}
});

Unfortunately, this is not correct.
In which direction should we move towards the right solution?
