I want my ViewPager implementation to cycle between views instead of stopping at the last view. For example, if I have 3 views to display via a ViewPager, it should return back to the first View after the third View on fling instead of stopping at that third view. I want it to return to the first page/view when the user flings forward on the last page
Thanks,
