| <p>Switch to androidx.viewpager2.widget.ViewPager2 and use androidx.viewpager2.adapter.FragmentStateAdapter instead.</p> |
| </aside> |
| <p>Implementation of PagerAdapter that represents each page as a <code><a href="/reference/androidx/fragment/app/Fragment.html">Fragment</a></code> that is persistently kept in the fragment manager as long as the user can return to the page. </p> |
| <p>This version of the pager is best for use when there are a handful of typically more static fragments to be paged through, such as a set of tabs. The fragment of each page the user visits will be kept in memory, though its view hierarchy may be destroyed when not visible. This can result in using a significant amount of memory since fragment instances can hold on to an arbitrary amount of state. For larger sets of pages, consider <code><a href="/reference/androidx/fragment/app/FragmentStatePagerAdapter.html">FragmentStatePagerAdapter</a></code>. </p> |
| <p>When using FragmentPagerAdapter the host ViewPager must have a valid ID set.</p> |
| <p>Subclasses only need to implement <code><a href="/reference/androidx/fragment/app/FragmentPagerAdapter.html#getItem(int)">getItem</a></code> and getCount to have a working adapter. </p> |
| <p>Here is an example implementation of a pager containing fragments of lists: {@sample frameworks/support/samples/Support4Demos/src/main/java/com/example/android/supportv4/app/FragmentPagerSupport.java * complete} </p> |
| <p>The <code>R.layout.fragment_pager</code> resource of the top-level fragment is: {@sample frameworks/support/samples/Support4Demos/src/main/res/layout/fragment_pager.xml * complete} </p> |
| <p>The <code>R.layout.fragment_pager_list</code> resource containing each individual fragment's layout is: {@sample frameworks/support/samples/Support4Demos/src/main/res/layout/fragment_pager_list.xml * complete}</p> |
