How can I change the position of an item in ListView dynamically in android

Question

I want to change the position of an item in ListView dynamically.How can I do that?

What do you mean with "change position"? swap item on place 2 with item on place 3 ? — Heiko Rupp, Apr 29 '11 at 06:33
yes,I want to have a button in my list view so on pressing that button that row should shift to first position in listview. — Arun, Apr 29 '11 at 06:41

The ListView is backed up by some data structure (e.g. a List<String>). So you can do

Pseudocode:

List<String> list = ...
ListView lv = ..
Adapter a = new Adapter(..., list);
lv.setOnClickListener(this);

onItemPressed(..., int position, ...) {
   tmp = list.get(0);
   list.set(0, list.get(position));
   list.set(position,tmp);
   a.notifyDataSetChanged();
}
