title: Disable collapsing of ExpandableListView
body: <p>The default behavior of <code>ExpandableListView</code> is to collapse a group when its header is clicked.  Is it possible to prevent this from happening?</p>
  
  <p>I've tried:</p>
  
  <ul>
  <li>Setting <code>OnTouchListener</code> on the list.  This interferes with scrolling.</li>
  <li>Setting an <code>OnGroupClickListener</code> on the list (in <code>onCreate()</code>).  This works for all clicks <em>after</em> the first.</li>
  </ul>
  
  <p>Has anyone else accomplished this?  Why might the <code>OnGroupClickListener</code> miss the first click?</p>
  
  <p>Thanks in advance for your suggestions.</p>
