Recently the androidx.fragment.app.FragmentManager is deprecated and no proper solutions are available.

Have tried to implement support V4 but did not work with AndroidX . It shows library not found.

PagerAdapter:

public ViewPagerAdapter(FragmentManager manager) {
    super(manager);
    //...
Thanks in advance.
                Both FragmentStatePagerAdapter and FragmentPagerAdapter have been deprecated. We need to use ViewPager2 + FragmentStateAdapter since AndroidX. Follow this: stackoverflow.com/a/66545099/8664401

It is not deprecated at the present time. For example, it is not marked as deprecated in the documentation.
  
'FragmentStatePagerAdapter(androidx.fragment.app.FragmentManager)' is deprecated
The single-parameter FragmentStatePagerAdapter constructor is deprecated. However, if you read the documentation for that constructor, you will find:
  
This constructor is deprecated.
  use FragmentStatePagerAdapter(FragmentManager, int) with BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT
So, replace FragmentStatePagerAdapter(fm) with FragmentStatePagerAdapter(fm, FragmentStatePagerAdapter.BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT), to retain the functionality from the original one-parameter constructor.
                Thanks, can try super(fm,FragmentStatePagerAdapter.BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT);

                today replace this:  super(fm,FragmentStatePagerAdapter.BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT);  to this:  super(fm,FragmentPagerAdapter.BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT);  the answer is also deprecated now

You can change default constructor as below:
public SectionsPagerAdapter(@NonNull FragmentManager fm, int behavior, Context mContext) {
    super(fm, behavior);
    this.mContext = mContext;
Full Adapter class as defined:
 * A [FragmentPagerAdapter] that returns a fragment corresponding to
 * one of the sections/tabs/pages.
public class SectionsPagerAdapter extends FragmentStatePagerAdapter {
    @StringRes
    private static final int[] TAB_TITLES = new int[]{R.string.tab_text_1, R.string.tab_text_2};
    private final Context mContext;
    public SectionsPagerAdapter(@NonNull FragmentManager fm, int behavior, Context mContext) {
        super(fm, behavior);
        this.mContext = mContext;
    @NotNull
    @Override
    public Fragment getItem(int position) {
        // getItem is called to instantiate the fragment for the given page.
        // Return a ProductSearchFragment (defined as a static inner class below).
        if(position == 0) {
            return new ProductSearchFragment();
        } else if(position == 1) {
            return new GenericSearchFragment();
        return new ProductSearchFragment();
    @Nullable
    @Override
    public CharSequence getPageTitle(int position) {
        return mContext.getResources().getString(TAB_TITLES[position]);
    @Override
    public int getCount() {
        // Show 2 total pages.
        return 2;
and You can call like:
SectionsPagerAdapter sectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager(), FragmentStatePagerAdapter.BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT, this);
Thank you.
public SectionsPagerAdapter(@NonNull FragmentManager fm,
                            int behavior) {
    super(fm,behavior);
Alternatively you can go 
Right Click -> Generate -> Override Methods and click on the first item as shown in the image.
You may need to change your code in other places after doing this.
