If you need scroll view programmatically, you can use smoothScrollToPosition but it supported only in API 8 and higher.

to refresh the listview call 

Adapter.NotifyDataSetChanged()

EDIT

generally listview's list item will have same height if you can calculate the height and call

ListView.scrollBy(x, y);

even simple you can call 

ListView.smoothScrollToPosition(position);

if you know the position

the listview should render the new items you added in the adapter(provided you call the notifydatasetchanged())
