Question

I have a ListActivity with a SimpleCursorAdapter, thus the list view contains data from a database. If I am looking at the list I want it to update (re-query) itself when new data is put in the database being used by the SimpleCursorAdapter. Is the best way to do this to set a content observer on the database and call a requery() on the cursor when new content comes in ?

Yes, when there are changes in the database ContentObserver, you should refresh the cursor by calling requery(). Now this method is deprecated though, just request a new cursor, so you can do this asynchronously and update your list view once the new cursor arrived.
