我正在开发一个带有侧边导航抽屉的应用程序。抽屉打开得很好，但是据称可以“单击”的文本似乎没有响应。动画显示当点击抽屉时有反馈（您可以听到声音），但没有任何结果。我试图放置 toast 消息以查看按钮是否注册了一个动作，但是按下时，没有 toast 出现。代码如下（我已经实现了NavigationView.OnNavigationItemSelectedListener）：

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_driver_home);
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        DrawerLayout drawer = findViewById(R.id.drawer_layout);
        NavigationView navigationView = findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(this);
        // Passing each menu ID as a set of Ids because each
        // menu should be considered as top level destinations.
        mAppBarConfiguration = new AppBarConfiguration.Builder(
                R.id.nav_home, R.id.nav_history, R.id.nav_settings,
                R.id.nav_help, R.id.nav_signout)
                .setDrawerLayout(drawer)
                .build();
        NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
        NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
        NavigationUI.setupWithNavController(navigationView, navController);

然后我实现了这个方法：

    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
        switch (menuItem.getItemId()){
            case R.id.nav_history: …
