title: Refreshing an ExpandableListView from within the adapter on Android
body: <p>I'm having trouble on how to refresh an <code>ExpandableListView</code> from within one of its childViews.</p>
  
  <p>The listView contains a list of files, and I want to offer a possibility to delete those files. But after a deletion is performed, the <code>ExpandableListView</code> needs to be refreshed. 
  I implemented my own adapter which extends the <code>BaseExpandableListAdapter</code>. It seems there is no way to get my parent object from within the overwritten <code>getChildView()</code> method to send a <code>notifyDataSetChanged()</code>. :-s</p>
  
  <p>I thought about sending an intent to my activity which contains information on the state of the groups (collapsed/expanded) and to refresh on receive, but even for this I would need the <code>ExpandableListView</code> object. </p>
  
  <p>How can this be done?</p>
  
  <p>Thanks in advance!</p>
  
  <p>Be well<br>
  S.</p>
