您可以使用以下代码删除片段：

 //remove the fragment from transaction manager
    FragmentManager frgManager = getSupportFragmentManager();
    Fragment fragment = frgManager.findFragmentByTag(tagName);
    if (fragment != null) {
        FragmentTransaction ft = frgManager.beginTransaction();
        ft.remove(fragment).commit();
    }
