if (state.isOpened()) {
// Request user data and show the results
Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {
@Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
// Display the parsed user info
}
}
});
}
我已经尝试按照facebook doc获取用户信息，在onSessionStateChange函数中，问题是，我跟随官方文档并显示
很奇怪Request.executeMeRequestAsync是折旧的，所以我想知道如何在最新的facebook sdk 3.6中获取用户信息？我想要做的是在用户登录时获取用户信息。非常感谢
更新
无论如何我还想问一下这种实现登录的方式是否正确？我的应用程序中有两个位置需要登录

我应该在所有活动中实现获取用户信息代码吗？感谢
答案 0 :(得分：1)
好的，请使用以下代码。
//定义textview以打印详细信息
TextView mfirstname, mlastname, middlename, mfullname, mbirthdate,
mfacebookLink, mfacebookId, mfacebookUnm, mgender, mEmail;
//从FB中检索数据的代码
Session.openActiveSession(this, true, new Session.StatusCallback() {
// callback when session changes state
@Override
public void call(Session session, SessionState state,
Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request.executeMeRequestAsync(session,
new Request.GraphUserCallback() {
@Override
public void onCompleted(GraphUser user,
Response response) {
if (user != null) {
mfirstname.setText(user.getFirstName());
mlastname.setText(user.getLastName());
middlename.setText(user.getMiddleName());
mfullname.setText(user.getName());
mbirthdate.setText(user.getBirthday());
mfacebookLink.setText(user.getLink());
mfacebookId.setText(user.getId());
mfacebookUnm.setText(user.getUsername());
String gender = user.asMap()
.get("gender").toString();
String email = user.asMap()
.get("email").toString();
mgender.setText(gender);
mEmail.setText(email);
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
.permitAll().build();
StrictMode.setThreadPolicy(policy);
} else {
Toast.makeText(getApplicationContext(), "Error...",
Toast.LENGTH_LONG);
}
}
});
