46.7 Creating the Fragment State Adapter

With the ViewPager2 instance added to the layout resource file, a new class which subclasses FragmentStateAdapter needs to be added to the project to manage the fragments that will be displayed when the tab items are selected by the user.

Add a new class to the project by right-clicking on the com.ebookfrenzy.tablayoutdemo entry in the Project tool window and selecting the New -> Java Class menu option. In the new class dialog, enter TabStateAdapter into the Name: field and click OK.

package com.ebookfrenzy.tablayoutdemo;
