Preference Fragment 与 BottomNavigationView 重叠

Question

I have 4 fragment, the last fragment is Setting Fragment using Preference Fragment:

public class SettingFragment extends Fragment {

   ...

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        getActivity().getFragmentManager().beginTransaction()
                .replace(android.R.id.content, new MyPreferenceFragment())
                .commit();
    }

   ...

    public static class MyPreferenceFragment extends PreferenceFragment {

        public MyPreferenceFragment(){}

        @Override
        public void onCreate(@Nullable Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.preferences);
        }
    }

}

My problem With first 3 fragments, bottom navigation bar still work But in last fragment is Setting Fragment, my fragment view overlaps my bottomNavigationView. I can not click to bottomNavigationView anymore. It relizes the click to item in fragmentView

How can I fix it?

Answer 1

You should use PreferenceFragmentCompat , if using androidx libraries

public class SettingsFragment extends PreferenceFragmentCompat {
    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
        setPreferencesFromResource(R.xml.preferences, rootKey);
    }
}

and a parent Fragment is not required if it's only a single screen, instead use the Preference Fragment directly.
