登錄facebook sdk 4.0.1與android應用程序

Question

我正在開發一個用戶可以連接到Facebook的android應用程序。我可以登錄並獲取配置文件信息，但是當我傳遞給另一個片段並返回登錄片段時，用戶提醒連接，但我看不到配置文件信息。當我傳遞或更改片段時如何保持這些信息可見？

這是我的代碼：

public class Share extends Fragment { 

LoginButton loginButton; 
TextView nameT,emailT,locationT,idT,msginfo; 
ProfilePictureView ppv; 
CallbackManager callbackManager; 
private ShareDialog shareDialog; 
File destination; 
String imagePath; 
Bitmap bmp; 
ImageView takePhoto,preview; 
private static final int REQUEST_IMAGE = 100; 

RelativeLayout otherview; 
AccessTokenTracker accessTokenTracker; 

private static final List<String> PERMISSIONS = Arrays.asList("publish_actions"); 
@Override 
public void onActivityResult(int requestCode, int responseCode, Intent data) 
{ 
    super.onActivityResult(requestCode, responseCode, data); 
    callbackManager.onActivityResult(requestCode, responseCode, data); 

} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    FacebookSdk.sdkInitialize(getActivity().getApplicationContext()); 
    callbackManager = CallbackManager.Factory.create(); 
    shareDialog = new ShareDialog(this); 

} 


@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
    View view = inflater.inflate(R.layout.share, container, false); 

    super.onCreate(savedInstanceState); 

    loginButton = (LoginButton)view.findViewById(R.id.authButton); 
    nameT= (TextView)view.findViewById(R.id.name); 
    locationT= (TextView)view.findViewById(R.id.location); 
    emailT= (TextView)view.findViewById(R.id.mail); 
    idT=(TextView)view.findViewById(R.id.id); 
    ppv = (ProfilePictureView)view.findViewById(R.id.fbimg); 
    otherview=(RelativeLayout)view.findViewById(R.id.other_views); 
    msginfo=(TextView)view.findViewById(R.id.msginfo); 






    List<String> permissionNeeds = Arrays.asList("user_photos", "email", "user_birthday", "user_location", "public_profile"); 

    loginButton.setReadPermissions(permissionNeeds); 
    loginButton.setFragment(this); 


    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() 
    { 
     @Override 
     public void onSuccess(LoginResult loginResult) 
     { 
      System.out.println("onSuccess"); 
      msginfo.setText("You can now share image on facebook"); 
      otherview.setVisibility(View.VISIBLE); 

      GraphRequest request = GraphRequest.newMeRequest 
        (loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() 
        { 
         @Override 
         public void onCompleted(JSONObject object, GraphResponse response) 
         { 
          // Application code 
          Log.v("LoginActivity", response.toString()); 
          //System.out.println("Check: " + response.toString()); 
          try 
          { 
           String id = object.getString("id"); 
           idT.setText(object.getString("id")); 
           ppv.setProfileId(object.getString("id")); 
           nameT.setText(object.getString("name")); 
           emailT.setText(object.getString("email")); 
           locationT.setText(object.getString("address")); 

           String name = object.getString("name"); 
           String email = object.getString("email"); 
           String gender = object.getString("gender"); 
           String birthday = object.getString("birthday"); 
           // String location = object.getString("location"); 
           // String location = object.getString("user_location"); 
           // String location = object.getString("address"); 




           System.out.println(id + ", " + name + ", " + email + ", " + gender + ", " + birthday); 
           // locationT.setText(location); 

          } 
          catch (JSONException e) 
          { 
           e.printStackTrace(); 
          } 

         } 
        }); 
      Bundle parameters = new Bundle(); 
      parameters.putString("fields", "id,name,email,gender, birthday,link"); 
      request.setParameters(parameters); 
      request.executeAsync(); 
     } 
     @Override 
     public void onCancel() 
     { 
      System.out.println("onCancel"); 
     } 

     @Override 
     public void onError(FacebookException exception) 
     { 
      System.out.println("onError"); 
      Log.v("LoginActivity", exception.getCause().toString()); 
     } 
    }); 

    return view; 

} 

}

將數據保存到outStateBundle在

void onSaveInstanceState(Bundle outState) 

和

void onCreate(Bundle savedInstanceState) 

您的片段

從savedInstanceState恢復。
