將片段添加到最頂層/顯示片段後面的backstack中

Question

我想知道是否有一種方法可以將片段添加到顯示片段後面的backstack中。因此，當用戶按下「後退按鈕」時，添加的片段將顯示給用戶。

Answer 1

據我所知，我不確定Fragment Manager可以做這樣的事情！

步驟-1：Why don't you add the fragment to backStack`當片段安裝到容器

步驟2：接下來onBackpressed或click of any view只是從容器

彈出片段Here is a sample from another Stackoverflow answer

fragmentTransaction.addToBackStack("fragB"); 
fragmentTransaction.addToBackStack("fragC"); 
Then in Fragment_C, pop the back stack using the name ie.. fragB and include POP_BACK_STACK_INCLUSIVE 

    someButtonInC.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 

      FragmentManager fm = getActivity() 
        .getSupportFragmentManager(); 
      fm.popBackStack ("fragB", FragmentManager.POP_BACK_STACK_INCLUSIVE); 
     } 
    });
