Android sort ListView

I have an ListActivity which use data from DB..

This view have a column with a numbers. What i need is to sort them in descending whey when i click on a button. Its not a problem to write a new select with a new sort type..But how to refresh ListA开发者_StackOverflow中文版ctivity ? Should I reuse setListAdapter ?

Since you are using a CursorAdapter it would be best to have the db sort the list. So just create a new Cursor and call setListAdapter again.

Yes you can reuse the setListAdapter() method, after recreating a new CursorAdapter with the new reordered Cursor.
