'FragmentStatePagerAdapter(androidx.fragment.app.FragmentManager)' is deprecated

Question

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: https://stackoverflow.com/a/66545099/8664401 — aQwus jargon, Mar 09 '21 at 10:31

Recently the androidx.fragment.app.FragmentManager is deprecated

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); — Latief Anwar, Jul 13 '19 at 09:23
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 — dherediat, Jul 03 '20 at 11:06

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.

Replace

public SectionsPagerAdapter(FragmentManager fm) {

    super(fm);
}

With

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.

Below solution in Kotlin :

class TasksPagerAdapter(fm: FragmentManager) : FragmentStatePagerAdapter(fm,BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT )

I ran into the same problem.

Change:

private class TestTest extends FragmentStatePagerAdapter

To:

private class TestTest extends FragmentPagerAdapter {

It will change:

import androidx.legacy.app.FragmentStatePagerAdapter;

To:

import androidx.fragment.app.FragmentPagerAdapter;

'FragmentStatePagerAdapter(androidx.fragment.app.FragmentManager)' is deprecated
