导航抽屉单击以打开另一个片段来替换TabLayout和ViewPager

Question

I have a project that has a navigation drawer and it includes with 2 item "Home" and "Message". "Message" page is a individual fragment and "Home" page is a tabLayout combine viewPager that includes 3 different fragment. What I want is "Message" fragment to replace Home's tabLayout and viewPager. Now my problem is when I try replace with "Message" fragment, the fragment itself didn't show anything but considering there is big TextView inside the "Message" fragment.

MainActivity's navigation click code

navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem item) {


            switch (item.getItemId()) {

                case 0:
                    drawerLayout.openDrawer(GravityCompat.START);
                    break;

                case R.id.Home:
                    getSupportActionBar().setTitle("Home");
                    viewPager.setAdapter(mSectionPageAdapter);
                    viewPager.setCurrentItem(1);
                    mTabLayout.setupWithViewPager(viewPager);
                    break;


                case R.id.Message:
                    mTabLayout.removeAllTabs();
                    getSupportActionBar().setTitle("Message");
                    getSupportFragmentManager().beginTransaction().replace(R.id.viewPager_mainActivity, friendMessageFragment).commit();
                    break;



            }

            drawerLayout.closeDrawer(GravityCompat.START);
            return true;
        }
    });

Image of Home tabLayout

Image of Message fragment, this fragment suppose to have a textView in the middle

I try to use getSupportFragmentManager() to replace my TabLayout but it seems not working at all. Does anyone has any Idea of what am I doing wrong or what am I lacking in this code, I have been struggling these days to solve this problem...

Answer 1

when it is only two items, you could use a ViewFlipper , which permits two child nodes.

or use a FrameLayout as a container and inflate fragments accordingly, instead of pre-existing XML .

as it is, it would inflate the second fragment, with no chance to return to the first one fragment.
