title: Detect single tap on top left of screen
body: <p>What i'm looking to do is detect when the user has touched a certain part of the screen, the top left corner. I've looked though the documentation </p>
  
  <p>developer.android.GestureDetector and developer.android.GestureDetector.SimpleOnGestureListener   </p>
  
  <p>I though of using onSingleTap() but have no idea how it would detect where it was touched. 
  Any help of ideas would be appreciated.
  Thanks!</p>
