How to auto refresh view when scrolling to the top on Android like ipad does
<p>In my app, i've already have an AllContentListScreen which extends Activity. It also has a customlistview and a custom adapter which retrieves data. 
What I am going to implement is when i scroll the screen to the very top of view, a spinning wheel will show and the data will be auto refreshed. 
This is definitely a UI issue. Any proper solution will be highly appreciated. Thanks !</p>
