Uncheck all checkboxes in a custom ListView

Question

I\'m trying to do an \"Unselect all\" button in a ListActivity to unchecked all checkboxes in a ListView managed by a custom SimpleCursorAdapter.

As suggested here,

Answer 1

Honestly I don't think the setChecked Methods will work with a custom layout. It expects the view to be a CheckedTextView with an id of text1.

And since the views are recycled I think the solution is to update whatever boolean in your objects in the list that determines if the checkbox is checked and then call adapter.notifyDataSetChanged(). You are changing the boolean state of the data (which is what really matters) and telling the Adapter to update the ListView. So the next time the views are drawn the checkbox will be checked correctly. And the current views that are shown will be redrawn.
