Android Facebook SDK onUserInfoFetched方法不起作用

Question

I have a problem about Facebook SDK for android. This code works for another activity of same application. I show to user the same FacebookLogin button in same xml file. But in the other activity, when I login on facebook, onUserInfoFetched method does not work! So I can not get the user.

The codes are in the same application. But in different activities. I can login both of them. but I can not get the user.

The codes below: This is the code which successfully work:

public class FacebookPreference extends Preference {
    private LoginButton loginButton;
    private ProfilePictureView profilePictureView;
    public static GraphUser user;
    private Context mContext;

    private enum PendingAction {
        NONE, POST_PHOTO, POST_STATUS_UPDATE
    }

    public FacebookPreference(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.setWidgetLayoutResource(R.layout.preferences_item_list_facebook);
        this.mContext = context;
    }

    @Override
    protected void onBindView(View view) {
        super.onBindView(view);
        loginButton = (LoginButton) view.findViewById(R.id.login_button);
        profilePictureView = (ProfilePictureView) view.findViewById(R.id.profilePicture);
        loginButton.setUserInfoChangedCallback(new LoginButton.UserInfoChangedCallback() {
            @Override
            public void onUserInfoFetched(GraphUser user) {
                FacebookPreference.user = user;
                updateUI();

            }
        });

    }

    private void updateUI() {
        Session session = Session.getActiveSession();
        if (user != null) {
            profilePictureView.setProfileId(user.getId());
        } else {
            profilePictureView.setProfileId(null);
        }
    }
}

This is the code which does not work.

public class FacebookLoginActivity extends Activity{

    LoginButton button;
    private ProfilePictureView profilePictureView;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.preferences_item_list_facebook);


        button = (LoginButton) findViewById(R.id.login_button);
        profilePictureView = (ProfilePictureView) findViewById(R.id.profilePicture);

        button.setUserInfoChangedCallback(new LoginButton.UserInfoChangedCallback() {
            @Override
            public void onUserInfoFetched(GraphUser user) {
                FacebookPreference.user = user;
                if(FacebookPreference.user != null)
                    Toast.makeText(FacebookLoginActivity.this,  FacebookPreference.user.getName().toString(), Toast.LENGTH_LONG).show();
                updateUI();

            }
        });

    };


    private void updateUI() {
        Session session = Session.getActiveSession();
        if (FacebookPreference.user != null) {
            profilePictureView.setProfileId(FacebookPreference.user.getId());
        } else {
            profilePictureView.setProfileId(null);
        }
    }
}

The xml File:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:facebook="http://schemas.android.com/apk/res-auto"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/menu_item_back"
    android:orientation="horizontal" >

    <com.facebook.widget.ProfilePictureView
        android:id="@+id/profilePicture"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        facebook:preset_size="normal" />

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:layout_marginRight="5dp"
        android:orientation="vertical" >

        <com.facebook.widget.LoginButton
            android:id="@+id/login_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" 
            facebook:confirm_logout="false"
            facebook:fetch_user_info="true" >
        </com.facebook.widget.LoginButton>
    </LinearLayout>

</LinearLayout>

Thanks for answers.

Answer 1

If you look at the other activity where this code works, you'll notice a UiLifecycleHelper member that shows up on each of the Activity lifecycle methods, as in:

@Override
protected void onResume() {
    super.onResume();
    uiHelper.onResume();
}

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

etc.

Implement this as well, and the callback should work.

Just Look at this this working nice for me And Look At this Answer Facebook Sdk User details

 private String UserInfoDisplay(GraphUser user) {    

    StringBuilder userInfo = new StringBuilder("");              
    String Name =  user.getName();
    String Id =   user.getId();
    String lastname =    user.getLastName();
    String firstname =  user.getFirstName();
    String getUsername =  user.getUsername();             

    String get_gender = (String) user.getProperty("gender");


    String image_url = "http://graph.facebook.com/"+user.getId()+"/picture?type=square";        

    Log.i("User information == >", Name +Id + lastname+ 
            firstname + image_url + get_gender +  getUsername + "usermail"+User_mail  );

    text.setText(Name + "  mail = " +User_mail);

    return userInfo.toString();
}
