title: clear ExpandableListView
body: <p>I am using an <code>ExpandableListView</code> along with a <code>ViewPager</code> so in <code>onPageSelected()</code> I need to clear the list. </p>
  
  <p>I know one way to do it for a <code>ListView</code> is <code>setAdapter(null)</code> but I get <code>The method setAdapter(ListAdapter) is ambiguous for the type ExpandableListView</code> error if I try it on <code>ExpandableListView</code>.</p>
