Android ListView Navigation With Up and Down Button
<p>I have made a custom <code>ListView</code> like the following </p>

<p><img src="http://i.stack.imgur.com/UKtNY.png" alt="Listview"></p>

<p>Currently I am showing only 2 views and  updating the <code>ListView</code> adapter when user clicks on the navigation button and calling <code>notifyDataSetChanged</code>.Is it possible to make default implementation on the navigation so that we get the default behavior of <code>ListView</code>?  </p>
