Like I said in your other thread, you probably don't want to be doing this. If I am to assume from your code-snippet that you have some kind of PacMan game, where the game is implemented in a SurfaceView and the PacMan is an ImageView... seriously, you don't want to do this.
The purpose of SurfaceView is to give you a dedicated drawing surface, which you can render to directly, independently of the normal update mechanism of the view hierarchy. Using an ImageView to render things completely defeats that purpose. If you are writing a game, you should be drawing your graphics into the SurfaceView yourself and not using the view hierarchy of managing the element there.
