存储android facebook登录数据进行解析

Question

有人可以帮助我如何将Facebook用户个人资料存储到解析库吗？我做了一个Android应用程序。我想要的是用户登录Facebook后，用户的信息（如电子邮件，姓名，性别）存储到解析库，然后应用程序显示新的活动。但是，我的应用程序在验证facebook登录后陷入登录对话框并且不存储任何解析库。有人能帮我吗？非常感谢

这是MainActivity.java

我在同一条船上，我是使用解析的新手，这对我有用。

//Make sure that a session is opened and that you asked for the required permission

if(ParseFacebookUtils.getSession().isOpened())
{

Request.newMeRequest(ParseFacebookUtils.getSession(), new Request.GraphUserCallback()
{
@Override
public void onCompleted(GraphUser user, Response response)
{
if (user != null)
{
 String Name = user.getName;
 String email = user.getEmail; 
//Use the get Method to get the info from facebook

//Then save it to the parse DB
 ParseObject post = new ParseObject("post");    
    post.put("name", Name); 
        post.saveInBackground();                         
}
  }
  }).executeAsync();
  }

我的LoginFragment看起来像这样，并将用户的Facebook名称存储到共享首选项。我使用https://developers.facebook.com/docs/android/login-with-facebook/v2.1来实现登录，使用https://developers.facebook.com/docs/graph-api/reference/v2.2/来从登录用户获取数据。
