Hi,

In code callSelection of ContactsListActivity, it calls ListView's
getSelectedItem and casts the return to Cursor.

 boolean callSelection() {
        ListView list = getListView();
        if (list.hasFocus()) {
            Cursor cursor = (Cursor) list.getSelectedItem();
        // omitted
...
}

But what I don't understand is ListView's getSelectedItem is calling
AdapterView's getSelectedItem.
And that should returns a View object, instead of a Cursor object, right?
