我搜索了过去两天，并没有成功找到从Facebook SDK 3.0 - 本地登录获取用户ID和访问令牌的方法。

I searched for past two days and was not successful in finding the method to get the user id and access token from Facebook SDK 3.0 - Native Login .

我是跟随facebook本机登录 - http://developers.facebook.com/docs/tutorials/androidsdk/ 3.0 / scrumptious / authenticate /

推荐答案

用户ID：

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);
    }  

user_ID & profileName 是字符串。

user_ID & profileName are string.

for accessToken：

for accessToken:

String token = session.getAccessToken();

对于用户电子邮件（我没有通过在设备或模拟器上运行检查此代码）：

for user email (i haven't check this code by running on device or emulator):

这些只是我的意见或你可以称之为建议

these are only my opinion or you can call it suggestion

setReadPermissions(Arrays.asList("email", ...other permission...));
//by analyzing the links bellow, i think you can set the permission in loginbutton as:
loginButton.setReadPermissions(Arrays.asList("email", ...other permission...));
user.asMap().get("email");
