How to attach a coordinator to the viewpager fragments?


Asked by Bentlee Todd on Nov 29, 2021 FAQ



Chris Banes has posted a sample on Github which shows exactly what you want to do. Here is the xml file that defines how one can indirectly attach a coordinator layout to the viewpager's fragments.
Also,
1 Initialize the ViewPager, TabLayout, and the Adapter. 2 Add the Pages (fragments ) along with the titles 3 Link the TabLayout to the Viewpager using the setupWithiewPager method.
Subsequently, FragmentStatePagerAdapter differs from the FragmentPagerAdapter only in one way that it destroys the fragments which are going off the screen. So Fragments are created, attached, destroyed and detached keeping the memory uses low. It holds maximum three fragments and keep destroying the off screen fragments.
Just so,
To set up our tab layout with ViewPager, we need to add a <ViewPager> element in our XML layout. For example, to make each child view in the swipe view to consume the entire tab layout, our layout should be like as shown following. To insert child views that represent each page, we need to add this layout to PagerAdapter.
Similarly,
FragmentPagerAdapter represents each page as a Fragment that is persistently kept in the fragment manager for as long as the user can return to the page. As the user swipes through pages of the ViewPager, the FragmentPagerAdapter extracts information from the data source and uses it to create Fragment s for the ViewPager to display.
