getPositionForSection and getSectionForPosition and getSections methods for ArrayAdapter
<p>Explain me the usage of <code>getPositionForSection(int)</code> and <code>getSectionForPosition(int)</code> and <code>getSections()</code> methods of <code>ArrayAdapter</code>?</p>

<p>I got a good explanation of <a href="http://stackoverflow.com/questions/5300962/getviewtypecount-and-getitemviewtype-methods-of-arrayadapter">getViewTypeCount and getItemViewType methods of ArrayAdapter</a>.</p>

<p>Thanks.</p>
