PagerTitleStrip is a non-interactive indicator of the current, next, and previous pages of a ViewPager. It is intended to be used as a child view of a ViewPager widget in your XML layout. Add it as a child of a ViewPager in your layout file and set its android:layout_gravity to TOP or BOTTOM to pin it to the top or bottom of the ViewPager. The title from each page is supplied by the method PagerAdapter#getPageTitle(int) in the adapter supplied to the ViewPager.
For an interactive indicator, see PagerTabStrip.
