Android錯誤：無法更改片段的標記。不使用viewpager

您好我有一個帶有textview的fragmentA。當我點擊它時，我去了有一個項目列表的fragmentB。單擊listitem時，iam會返回到fragmentA並使用listitem值更新textview。現在，當再次當它拋IllegalStateException異常TextView的IAM點擊：不能改變片段的標籤Android錯誤：無法更改片段的標記。不使用viewpager

boreselect.setOnClickListener(new OnClickListener() { 
      Fragment newContentbore = new BoreValuesListFragment(); 
      @Override 
      public void onClick(View v) { 

       Fragment currentFragment = getFragmentManager().findFragmentByTag(FragmentChangeActivity.mFragmentStack.peek()); 
       String tagbore = newContentbore.toString(); 
       FragmentChangeActivity.mFragmentStack.add(tagbore); 
       FragmentTransaction transaction = getFragmentManager().beginTransaction(); 
       transaction.add(R.id.content_frame, newContentbore,tagbore); 
       transaction.hide(currentFragment); 
       transaction.addToBackStack(tagbore); 
       transaction.commit(); 
      } 
     });

It's probably because you're adding the same fragment instance three times to the list. You should create a new instance for each page.
