"getView method checking if the position is the last one": When the getView is called repeatedly to populate the list with views, it is not guaranteed that the value of parameter 'position' is going to be 1, 2, 3, ... , n in sequence. In other words, the statement "if position is the last item in the list then the user is at the bottom of the list" is not guaranteed to be always true.
