如何纠正我的BottomNavigationView？

Question

我正在mainActivity中创建片段，最后我的BottomNavigationView给了我一个错误。

MainActivity：

protected BottomNavigationView.OnNavigationItemSelectedListener navListener = new BottomNavigationView.OnNavigationItemSelectedListener() {
    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
        Fragment selectedFragment = null;

        switch (menuItem.getItemId()) {
            case R.id.nav_home:
                selectedFragment = new HomeFragment();
                break;
            case R.id.nav_panorama:
                selectedFragment = new HomeFragment();
                break;
            case R.id.nav_favorite:
                selectedFragment = new FavoriteFragment();
                break;
        }
        getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, selectedFragment).commit();
        return true;
    }
};
