如何在底部导航中使用查看寻呼机

如何解决如何在底部导航中使用查看寻呼机

我想在View Pager中将Fragment创建为Bottom Navigation（实际上是fragment to fragment），但是遇到了这个问题：

如您所见，View Pager会在第一次正确加载，但下次不会正确加载。

这是我设置的BottomNavigation活动：

public class MainActivity extends AppCompatActivity {
NavController navController;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    BottomNavigationView navView = findViewById(R.id.nav_view);
    navController = Navigation.findNavController(this,R.id.nav_host_fragment);
    NavigationUI.setupWithNavController(navView,navController);
}

然后在其中设置视图寻呼机：

public View onCreateView(@NonNull LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
    super.onCreateView(inflater,container,savedInstanceState);
    View root = inflater.inflate(R.layout.fragment_home,false);

    //view pager
    SectionsPagerAdapter sectionsPagerAdapter =
            new SectionsPagerAdapter(getContext(),requireActivity().getSupportFragmentManager());
    viewPager = root.findViewById(R.id.home_viewpager);
    viewPager.setAdapter(sectionsPagerAdapter);

    //setup tabs
    tabs = root.findViewById(R.id.home_tabs);
    tabs.setupWithViewPager(viewPager);

    //toolbar
    Toolbar toolbar = root.findViewById(R.id.home_toolbar);
    ((AppCompatActivity)getActivity()).setSupportActionBar(toolbar);

    return root;
}

和View Paager的适配器：

public class SectionsPagerAdapter extends FragmentPagerAdapter {

@StringRes
private static final int[] TAB_TITLES = new int[]{R.string.tab_text_daily,R.string.tab_text_weekly};
private static final Fragment[] pageInstances = new Fragment[]{
        DailyReminderListFragment.newInstance(),DailyReminderListFragment.newInstance()
};
private final Context mContext;

public SectionsPagerAdapter(Context context,FragmentManager fm) {
    super(fm,BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT);
    mContext = context;
}

@NonNull
@Override
public Fragment getItem(int position) {
    return pageInstances[position];
}

@Nullable
@Override
public CharSequence getPageTitle(int position) {
    return mContext.getResources().getString(TAB_TITLES[position]);
}

@Override
public int getCount() {
    return pageInstances.length;
}

public static Fragment getPageInstance(int position) {
    return pageInstances[position];
}

如何修复它？
