FragmentPagerAdapter is deprecated problem

Question

Android Studio says fragment pager adapter is deprecated. How can I remove this error? here is the screenshot

public static class ViewPagerAdapter extends FragmentPagerAdapter {
    private ArrayList<Fragment> fragments;
    private ArrayList<String> titles;
    
    public ViewPagerAdapter(@NonNull FragmentManager fm) {
        super(fm);
    }

Answer 1

The FragmentPagerAdapter class in Android is indeed deprecated as of AndroidX library version 1.2.0. It is recommended to use FragmentStatePagerAdapter or FragmentPagerAdapter2 instead.

1. Replace FragmentPagerAdapter with FragmentStatePagerAdapter:

   public static class ViewPagerAdapter extends FragmentStatePagerAdapter {

2. Update the constructor of ViewPagerAdapter to call the appropriate superclass constructor:

   public ViewPagerAdapter(@NonNull FragmentManager fm) { super(fm, BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT); }

These changes will ensure that you are using the recommended replacement for FragmentPagerAdapter and resolve the deprecation problem.
