title: Draw onto an ImageView
body: <p>I studied the Androidreference for hours now, but don't really get the clue how to draw something (Text, Bitmap, Path ....) on a ImageView.</p>
  
  <p>Should I extend View and use the <code>onDraw()</code>-Method? If yes, how can I draw on my ImageView?</p>
  
  <p>Or is there any other way to achieve my goal?</p>
