Download the Library from Given Link.Layout that allows the user to swipe left and right through "pages" of content which are usually different fragments. This is a common navigation mode to use instead of ActionBar Tabs with Fragments.

If you want an "indicator" that displays the pages available at the top as shown in the screenshot above, you need to include a nested indicator view called a PagerTabStrip :. You might want to check out the popular ViewPagerIndicator for an improved page indicator. Next, let's suppose we have defined two fragments FirstFragment and SecondFragment both of which contain a label in the layout and have implementations such as:.

Now we need to define the adapter that will properly determine how many pages exist and which fragment to display for each page of the adapter by creating a FragmentPagerAdapter :. For more complex cases with many pages, check out the more dynamic approach with SmartFragmentStatePagerAdapter explained later. And now we have a basic functioning ViewPager with any number of fragments as pages which can be swiped between. We can access the selected page within the ViewPager at any time with the getCurrentItem method which returns the current page:.

If the Activity needs to be able listen for changes to the page selected or other events surrounding the ViewPagerthen we just need to hook into the ViewPager. We can use the ViewPager to display a tabbed indicator in order to create tabs to display our fragments.

An alternative approach to achieve this is to use the third-party PagerSlidingTabStrip library. In this way, we can use the same pager system described above and augment the pager with a tabbed navigation indicator. In certain cases, we may require a dynamic ViewPager where we want to get access to fragment instances or with pages being added or removed at runtime. If your ViewPager is more dynamic with many pages and fragments, we will want to use an implementation of the alternate FragmentStatePagerAdapter instead.

Below shows us how to use this and also intelligently cache the fragments for easy lookup. It does so by overriding the instantiateItem method and caching any created fragments internally. This solves the common problem of needing to access the current item within the ViewPager.

Now, we want to extend from SmartFragmentStatePagerAdapter copied above when declaring our adapter so we can take advantage of the better memory management of the state pager:. Now with this adapter in place, we can also easily access any fragments within the ViewPager with:. This pattern should save your app quite a deal of memory and allow for much easier management of fragments within your pager for the right situation.

In certain cases, we want to dynamically replace the Fragment shown for a given page within a ViewPager. For example, perhaps the page in the ViewPager currently displays a list of items and we want to have a detail view show up when an item is selected. There are two approaches for this: create a fragment container as a page or switch fragments from within the adapter.

The first approach is to have the page display a fragment container that switches between multiple child content fragments as outlined in this tutorial on the subject. You can view the working sample code here as well. The second approach is to switch the fragment that displays inside the FragmentPagerAdapter by overriding the getItem
