title: ExpandableListView, how to set the child height?
body: <p>I'm trying to set the <strong>ExpandableListView</strong> item (<code>ViewGroup</code>) height. Can it be set via xml (I don't need the divider height):</p>
  
  <pre><code>&lt;ExpandableListView
      android:id="@+id/lvExp"
      android:layout_height="match_parent"
      android:layout_width="match_parent"/&gt;
  </code></pre>
  
  <p>or it should be used this method, by manipulating the <strong><em>convertView</em></strong>:</p>
  
  <pre><code>    @Override
  public View getGroupView(int groupPosition, boolean isExpanded, View convertView,
                           ViewGroup parent) { ... }
  </code></pre>
  
  <p>Thanks in advance.</p>
