title: Android: Function called each frame
body: <p>I tought this was easier but I just can't find a solution:
  I have a simple View based Layout in Android with the <code>layout.xml</code> and all that and now I am currently looking for a function that is called each frame. I've tried overriding the <code>draw()</code> function in a custom layout (and calling <code>this.setWillNotDraw(false);</code> in the constructor) but this doesn't seem to be it.</p>
  
  <p>Can anyone tell me which function is called each frame in Android?</p>
