带导航抽屉的java bottomnavigationview

Question

我想实现一个底部导航视图，其中导航抽屉作为内部元素

我设法创建了一个bottomnavigationview和一个导航抽屉，但我不知道如何将导航抽屉放入bottomnavigationview

我的主要活动是java：

public class MainActivity extends AppCompatActivity {

private static final String TAG = "debinf MainActivity";

//public static final String FRAGMENT_KEY = "fragment";

private BottomNavigationView bottomNavigationView;
private NavigationView navigationView;
private DrawerLayout drawerLayout;
private NavController navController;

private AppBarConfiguration appBarConfiguration;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Log.i(TAG, "onCreate: ");

    bottomNavigationView = (BottomNavigationView) findViewById(R.id.main_bottom_nav);
    navigationView = (NavigationView) findViewById(R.id.main_sidebar);
    drawerLayout = (DrawerLayout) findViewById(R.id.main_drawer);

    setupNavigation();

}

private void setupNavigation() {
    Log.i(TAG, "setupNavigation: ");
    navController = Navigation.findNavController(this, R.id.main_fragment);
    appBarConfiguration =
            new AppBarConfiguration.Builder(R.id.navigation_friends,R.id.navigation_order,R.id.navigation_home,R.id.navigation_groups,R.id.navigation_settings,R.id.navigation_profile,R.id.navigation_all_activity) //Pass the ids of fragments from nav_graph which you dont want to show back button in toolbar
                    .setDrawerLayout(drawerLayout)
                    .build();

    NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration); //Setup toolbar with back button and drawer icon according to appBarConfiguration
    NavigationUI.setupWithNavController(navigationView, navController);
    NavigationUI.setupWithNavController(bottomNavigationView, navController);
    /*
     ** Listener for bottomNavigation must be called after been setupWithNavController
     ** This command will override NavigationUI.setupWithNavController(bottomNavigationView, navController)
     ** and the automatic transaction between fragments is lost
     * */
    //bottomNavigationView.setOnNavigationItemSelectedListener(this);
    //navigationView.setNavigationItemSelectedListener(this);

}


@Override
public void onBackPressed() {
    Log.i(TAG, "onBackPressed: ");
    if (drawerLayout.isDrawerOpen(GravityCompat.START)) {
        Log.i(TAG, "onBackPressed: DRAWER IS OPEN -  CLOSING IT");
        drawerLayout.closeDrawer(GravityCompat.START);
    } else {
        super.onBackPressed();
    }

}

@Override
public boolean onSupportNavigateUp() {
    Log.i(TAG, "onSupportNavigateUp: ");
    // replace navigation up button with nav drawer button when on start destination
    return NavigationUI.navigateUp(navController, appBarConfiguration) || super.onSupportNavigateUp();
}

我的活动是主要的。xml:
