I have compiled code from this thread as well as other threads on StackOverflow and created a project that can be used to implement ButteryProgessbar as well as "pull down to refresh". https://github.com/pauldmps/Gmail-like-Pull-Down-to-Refresh

Feel free to use the code in your application.

A big thanks to you guys.
