我可以使用以下代码获取姓名、电子邮件、性别和出生日期

loginButton.setReadPermissions(Arrays.asList("public_profile, email, user_birthday, user_friends,user_location"));//我还添加了user_location

    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
// App code
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object,GraphResponse response) {

Log.v("LoginActivity", response.toString());
}
});

Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender,birthday,location"); //and location parameter
request.setParameters(parameters);
request.executeAsync();


}

@Override
public void onCancel() {
// App code
Log.v("LoginActivity", "cancel");
}

@Override
public void onError(FacebookException exception) {
// App code
Log.v("LoginActivity", exception.getCause().toString());
}
});

但它只返回以下值。

07-22 12:53:05.639: E/Fb data(6560): {"id":"989472891104","name":"Karan Mer","email":"karan_mer2012@yahoo.co.in","gender":"male"}

我怎样才能得到它???

最佳答案

如果不在 Facebook 上提交应用程序以供审核,我们将无法获取 Facebook 用户的位置。但出于测试目的,您可以获得 App Developer、Admin 或 Tester 的位置。

从这里下载源代码 ( Get location of facebook user using Graph API in android )

添加这个依赖:

compile 'com.facebook.android:facebook-android-sdk:4.0.1'
