title: Hide scrollbar when scrolling listview programmatically?
body: <p>I made a chat application and have Chat Activity in it.
  To display messages in dialog-like style I use ListView.</p>
  
  <p>When I receive or send message to chat I need ListView to scroll down to it's end. Now I doing it with</p>
  
  <pre><code>chatView.smoothScrollToPosition(chatAdapter.getCount());
  </code></pre>
  
  <p>But when listview scrolls down it shows an animated vertical scrollbar.
  However. I want to display the vertical scrollbar when a user scrolls the list by himself (using finger) and NOT show the scrollbar when I do it programmatically. </p>
  
  <p>How can I achieve that?</p>
