Android Implement Swipe Views

March 10, 2017

To insert child views that represent each page, you need to hook this layout to a PagerAdapter. There are two kinds of adapter you can use:

FragmentPagerAdapter
This is best when navigating between sibling screens representing a fixed, small number of pages.
FragmentStatePagerAdapter
This is best for paging across a collection of objects for which the number of pages is undetermined. It destroys fragments as the user navigates to other pages, minimizing memory usage.
