Is there a way to prevent the listview from scrolling to its top position when its adapter's data is changed?

Question

I\'m having a bit of trouble preserving the scroll position of a list view when changing it\'s adapter\'s data.

What I\'m currently doing is to create a custom Array

Check out: Maintain/Save/Restore scroll position when returning to a ListView

Use this to save the position in the ListView before you call .clear(), .addAll(), and . notifyDataSetChanged().

int index = mList.getFirstVisiblePosition();
View v = mList.getChildAt(0);
int top = (v == null) ? 0 : v.getTop();

After updating the ListView adapter, the Listview's items will be changed and then set the new position:

mList.setSelectionFromTop(index, top);

Basically you can save you position and scroll back to it, save the ListView state or the entire application state.
