Android Expandable ListView Icon (Group Indicator)
<p>I have been able to successfully swap in my own image for the expandable listview arrows. I have two issues at the moment.</p>

<p>One is that the icons i substitue in with the code below are each strechted to the height of the row and too wide as well. The second is, that this code is only changing the initial state of the Group Indicator. How do I change it from one image to another when a particular row is open?</p>

<pre><code>Drawable plus = (Drawable) getResources().getDrawable(R.drawable.plus);
getExpandableListView().setGroupIndicator(plus);
</code></pre>
