Expandable listview for each item in a listview
<p>How can I accomplish to make the expandable listview like this:</p>

<p><img src="http://i.stack.imgur.com/eoTbl.png" alt="enter image description here"></p>

<p><img src="http://i.stack.imgur.com/rMTzb.png" alt="enter image description here"></p>

<p>Just ignore that the content of each item is different, how can I make this?</p>
