Android 如何从子活动而不是主活动使用facebook登录

我对所有这些facebook和android SDK的整合都是陌生的。 我按照facebook开发者提供的初学者教程进行了登录，结果成功了， 但当我将它与我的应用程序结合使用时，它无法工作，原因如下：

在我的项目中，我编写了一个从主活动到另一个Fragmentactivity（FBProfile）的调用，该活动调用登录片段。 facebook认证后，它将返回到MainActivity中的OnResume，而不是LoginFragment中的overided onActivityresult

我需要创建此流（如果可能）： MainActivity->FBProfile（FragmentActivity）->LoginFragment->Facebook->LoginFragment

由MainActivity调用的活动：

public class FBProfile extends FragmentActivity{


  private LoginFragment loginfragment; 


  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      // TODO Auto-generated method stub
      Log.i(" Facebook: ", "FBProfile->OnCreate");
      if(savedInstanceState==null)
      {
loginfragment=new LoginFragment();
getSupportFragmentManager().beginTransaction().add(android.R.id.content, loginfragment).commit();
}
else
{
loginfragment=(LoginFragment) getSupportFragmentManager().findFragmentById(android.R.id.content);
}
}  
}

public class LoginFragment extends Fragment {
 private View login_view;
 private boolean isResumed = false;   
 private static final String TAG="LoginFragment";
 private UiLifecycleHelper uihelper;
 private LoginButton authbutton;
 private TextView userInfoTextView;
 private Session.StatusCallback callback=new Session.StatusCallback() {

        @Override
        public void call(Session session, SessionState state, Exception exception) {
            // TODO Auto-generated method stub
            onSessionStatechange(session, state, exception);
        }
    };

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        Log.i(" Facebook: ", "FBProfile->OnCreate->LoginFragment");
        login_view=inflater.inflate(R.layout.profilepage, container,false);
       userInfoTextView = (TextView) login_view.findViewById(R.id.userInfoTextView);

        authbutton=(LoginButton) login_view.findViewById(R.id.login_button);
        authbutton.setFragment(this);
        authbutton.setReadPermissions(Arrays.asList("public_profile","email","user_birthday"));

        return login_view;
    }

    @SuppressWarnings("deprecation")
    private void onSessionStatechange(Session session,SessionState state,Exception exception)
    {
        if (isResumed) {
            if (session != null && session.isOpened()) {
                Intent intent = new Intent(getActivity(),
                        FBProfile.class);
                intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
                        | Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(intent);
            }
        }
        if(state.isOpened()){
            Log.i(" Facebook: ", "LOGGED IN....");
            userInfoTextView.setVisibility(View.VISIBLE);

             // Request user data and show the results
            Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {

                @Override
                public void onCompleted(GraphUser user, Response response) {
                    // TODO Auto-generated method stub
