我有一个 buttonLoginLogout Button，它是一个 facebook 登录按钮（我将 facebook sdk 导入到我的项目中），这是我在 mainActivity 中的方法：

它取自 Facebook 活动的 LoginUsingActivityActivity 示例，我没有看到 GraphUser 或未完成的方法，所以我怎样才能获得通过 facebook 连接的用户详细信息...

我尝试添加“void onCompleted”方法（最后如您所见），但是我无法覆盖它并且我无法获取用户详细信息，并且当我登录到 Facebook（并且登录成功）时，它没有到达 oncompleted方法...

如何获取成功登录 facebook 的 GraphUser？

另外，我在这里添加了 onCompleted 方法，它不在这里，它说它没有覆盖另一个方法..

多谢

把它写在一个方法中：

final Session session = Session.getActiveSession();
    if (session != null && session.isOpened()) {
        // If the session is open, make an API call to get user data
        // and define a new callback to handle the response
        Request request = Request.newMeRequest(session, new Request.GraphUserCallback() {
            @Override
            public void onCompleted(GraphUser user, Response response) {
                // If the response is successful
                if (session == Session.getActiveSession()) {
                    if (user != null) {
                        user_ID = user.getId();//user id
                        profileName = user.getName();//user's profile name
                        userNameView.setText(user.getName());
                    }   
                }   
            }   
        }); 
        Request.executeBatchAsync(request);
    }

并确保仅在成功登录后调用此方法。这意味着你应该从onActivityResult.
