AbsListView and AbsSpinner are designed to be extended within the framework. They could also be extended in 3rd party apps but we did not expose all the necessary protected fields and methods on purpose. We want to be very careful in how we expose such APIs so as to not get stuff for future extensions and internal changes. Our current recommendation is you simply copy/paste the code you need inside your app.
