navigationView侧滑菜单+fragment：为什么点击item切换fragment失败？只能切换一次

Question

//转换fragment
public void SwitchFrag(Fragment targetFragment){

    FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
    //如果Fragment没有被添加，则添加，否则显示
    if(!targetFragment.isAdded()){

        transaction.hide(currentFragment).add(R.id.dl_cebian, targetFragment).commit();
    }
    else{
        transaction.hide(currentFragment).show(targetFragment).commit();
    }
    currentFragment = targetFragment;
}
