您需要电子邮件权限才能阅读用户的电子邮件地址。那   将在[uid]或我的请求中为你的json-response添加一个电子邮件标签。

我不确定,但如果我没弄错,可以从Facebook提供的Graph API获取此信息。您需要登录才能访问它。

LoginButton是我在视图中实现的Facebook SDK本机对象(com.facebook.widget.LoginButton)。

查看代码:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:id="@+id/login_options"
    xmlns:android="http://schemas.android.com/apk/res/android">
    <com.facebook.widget.LoginButton
        android:id="@+id/authButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="30dp">
        </com.facebook.widget.LoginButton>
    </RelativeLayout>

Java代码:

RelativeLayout view = (RelativeLayout) inflater.inflate(R.layout.login_options, container, false);    

LoginButton authButton = (LoginButton) view.findViewById(R.id.authButton);

authButton.setReadPermissions(Arrays.asList("email"));
