title: Android: BitmapDrawable.Draw(Canvas) Doesn't seem to work
body: <p>I am trying to tile a 20x20 background onto my Custom View but for some reason I am unable too.</p>
  
  <pre><code>    BitmapDrawable background;
      background = new BitmapDrawable(BitmapFactory.decodeResource(getResources(), R.drawable.back));
      background.setTileModeXY(Shader.TileMode.REPEAT, Shader.TileMode.REPEAT);
      background.draw(canvas);
  </code></pre>
  
  <p>Does anyone have an idea why it isn't working?</p>
