Android更改时关闭ActivityDialog

Question

我想在关闭活动时更改Fragment。我试图进入活动，FragmentTransaction但它不是正确的方式。我能怎么做？谢谢

Fragment newFragment = new Ele_Fragment(); 
     FragmentTransaction transaction = getFragmentManager().beginTransaction(); 

     // Replace whatever is in the fragment_container view with this fragment, 
     // and add the transaction to the back stack 
     transaction.replace(R.id.frame_container, newFragment); 
     transaction.addToBackStack(null); 

     // Commit the transaction 
     transaction.commit(); 

Answer 1

尝试添加标签的addToBackStack强似空

.addToBackStack(Ele_Fragment.TAG); 

这种方式，您有一个钩到您传递的片段。
