ExpandableListView and SimpleCursorTreeAdapter

I want to use an ExpandableListView backed with a SimpleCursorTreeAdapter. So far, I can't get anything on my screen.

To do this, I create a class of my own derived from the SimpleCursorTreeAdapter class. In this class, I override the getChildrenCursor to retrieve the children of the group specified in the parameters list. I create an instance of this class with an SQLiteCursor for the source of data and my views are simple TextViews, both for the group and the children. My cursor has some data (2 rows in my example), and I get no error message, but the ExpandableListView doesn't display anything on the screen.

I can add that, with a class derived from the BaseExpandableListAdapter, I have been able to see my data.

Am I missing something? Is there a place where I could find a code sample using the SimpleCursorTreeAdapter class in conjunction with the ExpandableListView class?
