title: Android: Update Listview after Thread loads data from the net
body: <ol>
  <li>I like that my GUI appears immediately when the user starts the app.</li>
  <li>Then some data (text, pictures) gets loaded in the background (like YouTube app).</li>
  <li>The ListView and Gallery gets updated automatically with this new data.</li>
  </ol>
  
  <p>I initiate my ListView, start a Thread and load the data... and then the ListView does not get updated!
  Several people told me I should use <code>notifyDataSetChanged()</code>.
  But I cannot place this command in my Thread (just unknown).</p>
  
  <p>Any ideas?</p>
