title: ListView: how do I wait until it's loaded up?
body: <p>I'm using a ListView with an ArrayAdapter, and code executing after <code>ListView.setAdapter(ArrayAdapter,...)</code> is seeing <code>ListView.getChildCount()==0</code>.</p>
  
  <p>Is there a way t wait for the UI thread to finish filling the ListView before continuing?</p>
  
  <p>Thanks in advance,
  Lenny</p>
