Facebook登錄使用片段Android

我想爲Android設置Facebook登錄。我已經按照網上所有的文件來得到這個去，我的主要參考是this。Facebook登錄使用片段Android

我的代碼中沒有「錯誤」，但沒有出現任何內容，而且我確實有一種感覺，如果出現某種情況，什麼也不會發生。讓我告訴你更好的理解：

ManageFacebookFragment

public class ManageFacebookFragment extends Fragment { 
    final static String ARG_POSITION = "position"; 
    int mCurrentPosition = -1; 

private static final String TAG = MainScreenFragmentPagerAdapter.class.getSimpleName(); 
private UiLifecycleHelper uiHelper; 
private final List<String> permissions; 


public ManageFacebookFragment() { 
    permissions = Arrays.asList("user_status"); 
} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    /** Getting the arguments to the Bundle object */ 
    final Bundle data = getArguments(); 

    /** Getting integer data of the key current_page from the bundle */ 
    mCurrentPosition = data.getInt("current_page", 0); 
    uiHelper = new UiLifecycleHelper(getActivity(), callback); 
    uiHelper.onCreate(savedInstanceState); 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 

    View v = inflater.inflate(R.layout.settings_accounts_facebook, container, 
      false); 

    LoginButton authButton = (LoginButton) v.findViewById(R.id.authButton); 
    // authButton.setFragment(this); 
    authButton.setReadPermissions(permissions); 

    return v; 
} 


@Override 
public void onResume() { 
    super.onResume(); 

    // For scenarios where the main activity is launched and user 
    // session is not null, the session state change notification 
    // may not be triggered. Trigger it if it's open/closed. 
    Session session = Session.getActiveSession(); 
    if (session != null && (session.isOpened() || session.isClosed())) { 
     onSessionStateChange(session, session.getState(), null); 
    } 

    uiHelper.onResume(); 
} 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    uiHelper.onActivityResult(requestCode, resultCode, data); 
} 

@Override 
public void onPause() { 
    super.onPause(); 
    uiHelper.onPause(); 
} 

@Override 
public void onDestroy() { 
    super.onDestroy(); 
    uiHelper.onDestroy(); 
} 

@Override 
public void onSaveInstanceState(Bundle outState) { 
    super.onSaveInstanceState(outState); 
    uiHelper.onSaveInstanceState(outState); 
} 

private void onSessionStateChange(Session session, SessionState state, Exception exception) { 
    if (state.isOpened()) { 
     Log.i(TAG, "Logged in..."); 
    } else if (state.isClosed()) { 
     Log.i(TAG, "Logged out..."); 
    } 
} 

private final Session.StatusCallback callback = new Session.StatusCallback() { 
    @Override 
    public void call(Session session, SessionState state, Exception exception) { 
     onSessionStateChange(session, state, exception); 
    } 
}; 

}

settings_accounts_facebook.xml

<com.facebook.widget.LoginButton 
    android:id="@+id/authButton" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center_horizontal" 
    android:layout_marginTop="30dp" 
    />

基本上所有的我已經是按鈕，我希望能夠按獲得用戶使用Facebook進行身份驗證...現在，當我運行應用程序時，它僅僅是一個空白屏幕......我想知道這是否與片段實現有關對Facebook的登錄，不知道。任何想法或建議將不勝感激。非常感謝！

解決 - 忘了每個子片段添加到尋呼機 - 這是將一個默認的空白項。
