If it is just a refresh and not an entirely new list or additions/ removals of elements, use notifyDataSetInvalidated() instead. I think it's a bit more efficient.
But, as far as i know, you can't specifiy a range of elements. But you can optimize it yourself. I do this at times using the list-item view's getTag() and setTag() methods. If the getTag() returns an object that is different than you would expect (with respect to the list-item's position), refresh the view's contents. Otherwise, leave it alone.
