This is not the number of children of the ListView. getChildCount() on
ListView is the number of children of the ListView.

No, you have 8 rows in your ListView. Your adapter might have 10
items, but you only have 8 rows in the ListView.

Of course. That's what you wrote.
If you didn't want it to crash, do not compare apples (number of items
in the adapter) to oranges (number of children of the ListView).
