How to redefine the scroll in a listview
<p>I have a listview with headers as you can see here : <a href="http://jsharkey.org/blog/2008/08/18/separating-lists-with-headers-in-android-09/" rel="nofollow">http://jsharkey.org/blog/2008/08/18/separating-lists-with-headers-in-android-09/</a>  </p>

<p>I would like to redefine the scroll behavior, to always let the current header on the top of the list. So if I have 20 items under my header, the listview scrolls on these items, keeping the header on screen, and then, the next header comes and takes the place of the previous one.  </p>

<p>Is there a method to do that ?</p>
