FragmentManager fragmentmanger = getSupportFragmentManager();
FragmentTransaction fragmenttransaction = fragmentmanager.begintransaction();//这一步不进行也可以查找
Fragment fragment = fragmentManager.findFragmentById(R.id.fragment);
if(fragment!==null){
fragmentTransaction.remove(fragment).commit;
}
//查找是删除的基础
