App freezes forever when Fragment get's displayed

Question

Since I implemented a BottomAppBar my App isn't responding when a certain Fragment should get displayed even though I haven't changed anything. There isn't an error message either and all other Fragments which are getting displayed when another item in the BottomNavigationBar is clicked work fine.

Fragment:

public class StatisticsFragment extends Fragment {

private TabLayout mTabLayout;
private ViewPager mViewPager;

private BankAccountsStatisticsFragment bankAccountsStatisticsFragment = new BankAccountsStatisticsFragment();
private BillsStatisticsFragment billsStatisticsFragment = new BillsStatisticsFragment();
private CategoriesStatisticsFragment categoriesStatisticsFragment = new CategoriesStatisticsFragment();
private GoalsStatisticsFragment goalsStatisticsFragment = new GoalsStatisticsFragment();


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View inflatedView = inflater.inflate(R.layout.fragment_statistics, container, false);

    mTabLayout = (TabLayout) inflatedView.findViewById(R.id.tl_statistics);
    mViewPager = (ViewPager) inflatedView.findViewById(R.id.vp_statistics);

    mViewPager.setAdapter(new Adapter(getChildFragmentManager()));
    mTabLayout.setupWithViewPager(mViewPager);

    return inflatedView;
}

private class Adapter extends FragmentPagerAdapter {

    private static final int TABS = 4;

    public Adapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        switch (position){
            case 0: return bankAccountsStatisticsFragment;
            case 1: return billsStatisticsFragment;
            case 2: return categoriesStatisticsFragment;
            case 3: return goalsStatisticsFragment;
            default: throw new IllegalStateException("Couldn't find a fragment for position " + position);
        }
    }

    @Override
    public CharSequence getPageTitle(int position) {
        switch (position){
            case 0: return getString(R.string.tab_bank_accounts);
            case 1: return getString(R.string.tab_bills);
            case 2: return getString(R.string.tab_categories);
            default: return getString(R.string.tab_goals);
        }
    }

    @Override
    public int getCount() {
        return TABS;
    }
}

}

Inflating a Layout and creating a Fragment transition (like the "FragmentManager....replace().commit()") are done in the MainThread where the UserInterface is rendered, so the UserInterface will freeze in these moments. I think you have to pre-load the "bad" Fragment and just HIDE it instead of Destroy it...in this way the next time you want to create it is already ready.

But it freezes forever and not for a certain time – eli2003 Dec 06 '18 at 16:51
so you mean that I should load all Fragments into alayout and hide or show the one which should be displayed? – eli2003 Dec 07 '18 at 19:03

the question was about freezing infinitely, not slight stutter – pete Aug 11 '20 at 01:57
