So aktualisieren Sie die erste Registerkarte auf Aktionsleiste Spinner Element ausgewählt

Question

Ich versuche, die 1. Registerkarte auf Spinner Element ausgewählt aktualisieren, aber es zeigt den Fehler No view found Ausnahme zeigt, wenn ich versuche, das gleiche Fragment aufrufen.

Refresh Same Fragment Code:

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

Answer 1

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(); 
      } 
     } 
    } 
}
