선택한 작업 표시 줄 회 전자 항목의 첫 번째 탭을 새로 고치는 방법

Question

선택한 회 전자 항목의 첫 번째 탭을 새로 고치려고하지만 동일한 조각을 호출하려고 할 때보기에 예외가 없습니다.라는 오류가 표시됩니다.

새로 고침 같은 조각 번호 :

DashBoardFragment currentFragment = new DashBoardFragment(); 
    FragmentTransaction fragTransaction = getFragmentManager().beginTransaction(); 
    //fragTransaction.detach(currentFragment); 
    //fragTransaction.attach(currentFragment); 
    fragTransaction.replace(R.id.home_container, currentFragment); 
    fragTransaction.commit();

public void Refresh() { 
    FragmentManager fragmentManager = getActivity().getSupportFragmentManager(); 
    List<Fragment> fragments = fragmentManager.getFragments(); 
    for (Fragment fragment : fragments) { 
     if (fragment != null && fragment.isVisible()) { 
      if (fragment instanceof SummaryReportsFragment) { 
       Toast.makeText(getContext(), "Yes", Toast.LENGTH_LONG).show(); 
       FragmentTransaction fragTransaction = getActivity().getSupportFragmentManager().beginTransaction(); 
       fragTransaction.detach(fragment); 
       fragTransaction.attach(fragment); 
       fragTransaction.commit(); 
      } 
     } 
    }
