如何通过后退按钮（箭头）将活动导航到片段？

Question

我试过了

YourFragment mapFragment = new YourFragment();
FragmentManager manager = getFragmentManager();

manager.beginTransaction().replace(R.id.landlord_apartment, mapFragment, mapFragment.getTag()).commit();

但是我的活动与我的片段重叠？ 我该如何解决？ 我想通过操作栏箭头按钮返回

如果您从片段返回片段，请尝试此解决方案

    FragmentManager fragmentManager = getFragmentManager();
                FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                YourFragment yourFragment = new YourFragment();
                fragmentTransaction.replace(R.id.fragment_container, yourFragment);
                fragmentTransaction.addToBackStack(null);
                fragmentTransaction.commit();

但从活动到片段只需添加

 finish();
