FragmentSwitcher is an adapter-based, state-saving fragment container similar to a ViewPager.
It was designed with the NavigationDrawer and Tab patterns in mind but can be used anywhere that you switch between fragments and would like to retain instance state.
- Retains instance state of Fragments even when removing them from your activity.
- Compatible with existing adapters: FragmentPagerAdapter and FragmentStatePagerAdapter
- Adapter determines fragment retention policy. See the documentation for the two adapters above.
- Includes two new adapters: FragmentArrayPagerAdapter and FragmentStateArrayPagerAdapter. You no longer have to subclass PagerAdapter to use FragmentSwitcher, just supply an array of fragments.
The sample app shows a demo of a navigation drawer with a lot fragments in a FragmentStateArrayPagerAdapter that can maintain the state of an edittext and listview. The sample also includes an example of saving a ListView's adapter content to InstanceState and restoring it later.
