Answer 1

Make on touch listener for the view where you draw the image. And there change the visibility of the view. Not in onDraw();

Edit:

If you set the Bitmap image for example on a ImageView, then onTouchListener() must be applied on the ImageView. Bitmap image is only a data that is supplied to the view(s).
