Scroll PullToRefreshScrollview automatically in android

I have a Listview, FrameLayout inside PullToRefreshScrollview. And I'm
loading a fragment into framelayout. Data is loading into listview using
lazy adapter. I'm able to see the fragment/framelayout while listview is
loading. But Scrollview is automatically scrolling to the postion of
listview after data is loaded into listview and framelayout is not
visible. How can I scroll the scrollview to top? Please help me. Thanks in
advance
