How to change group title in BaseExpandableListAdapter
<p>I created a sample about expandableList, and the structure is as below, </p>

<ul>
<li>MainGroup 1 (Expandable)                  text
<ul>
<li>SubGroup 1 (Expandable)
<ul>
<li>Child View</li>
</ul></li>
</ul></li>
</ul>

<p>The requirement is when I was clicking childView, that 'text' filed will change to childView text, do you know how to handle this?</p>
