我想避免在切换 BottomNavigationView . 我真的不知道怎么做。原因是当我在标签1和标签2之间切换时，手机的延迟太大。

BottomNavigationView navView = findViewById(R.id.nav_view);

AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(
        R.id.navigation_home, R.id.navigation_dashboard, R.id.navigation_notifications)
        .build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
NavigationUI.setupWithNavController(navView, navController);

谢谢你的帮助。
