title: runOnUiThread inside a View
body: <p>I'm making a custom <code>ImageView</code> . One of the methods is to load an image from a URL. And I want to retrieve the Bitmap in a Thread and load the bitmap in the UI thread.</p>
  
  <p>How can I make a <code>runOnUIThread()</code> call for painting the bitmap?</p>
  
  <p>Is there some kind of built in function? Or should I create a <code>Handler</code> in the constructor and use it for running runnables in the UI thread?</p>
