title: Adding "Loading"-image on top of ListView
body: <p>I'd like to add a "Loading"-<code>Image</code> on the top of my <code>ListView</code> while all items are loading, if there are a lot of items being loaded, I still want a nice user experience.</p>
  
  <p>So therefore I want a floating <code>Image</code> ( Animated GIF ? ) on top of my <code>ListView</code>.</p>
  
  <p>How would one solve this and once you have the floating image or control, how do you make the GIF animated?</p>
