title: Expand all children in expandable list view
body: <p>I would like to expand all children while the expandable list view is populated.
  Currently my code looks like this:</p>
  
  <pre><code>ExpandableListView listView = (ExpandableListView) findViewById(R.id.view);
  int count = viewAdapted.getGroupCount();
  for (int position = 1; position &lt;= count; position++)
      listView.expandGroup(position - 1);
  </code></pre>
  
  <p>which is pretty ugly.
  Is there a nicer way to do this?</p>
