I have an issue on ICS too.

I have a chat message list activity, everytime after i send the message, i need to scroll the listview to bottom smoothly. So after i called notifyDataSetChanged(), i called method smoothScrollToPosition(). On other android build versions, it works well. But on ICS, it is very strange. If my listview is at bottom, i tested 3 cases. if I append one new item to the listview, it won't scroll. If i append two new items to the list view --> it will scroll well. And If i scroll the listview up a few pixes, after i append one new item, it will scroll well. After a lot of google search and test, i feel helplessness about this. At last, every time i setdata to listview, i append an empty view(1px) at the last position, though this is not a good method, but it works for me.
