小编Bad*_*mar的帖子

我想在一个活动中制作一个同时带有底部导航和标签的应用程序。但是当我试图将选项卡放在导航片段中时，会出现一个异常。 我想用两个工具栏这样设计，一个是底部导航，另一个是选项卡

请帮忙

启动器Activity.java

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


// Bottom Navigation Start

        BottomNavigationView bottomNav = findViewById(R.id.bottom_navigation);
        bottomNav.setOnNavigationItemSelectedListener(navListner);

        getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new HomeFragment()).commit();

// Bottom Navigation

    }


// Bottom Navigation Start
    private BottomNavigationView.OnNavigationItemSelectedListener navListner = new BottomNavigationView.OnNavigationItemSelectedListener() {
                @Override
