在Android中使用SDK 3.5从FriendPickerFragment获取Facebook朋友列表

Question

I am using Facebook SDK 3.5 and i am a bit confused. If i use FriendPickerFragment (from their example) it populates the fragment with the list of friends, but I only want to have the JSON or list of GraphUser only.

Does anybody know how to get that information using the picker fragment. I don't understand how they get the data to populate the fragment.

This is how i can see what is selected from the populated list:

List<GraphUser> selectedUsers = friendPickerFragment.getSelection();
    for (GraphUser selectedUser : selectedUsers) {  System.out.println("selectedUser: " + selectedUser);
}

But how can i get the entire list(selected or not)?

Answer 1

 Request request = Request.newMyFriendsRequest(
 Session.getActiveSession(),
 new Request.GraphUserListCallback() {

 @Override
 public void onCompleted(List<GraphUser> users, Response response) {
     System.out.println("Users: " + users);
     }
            });
 request.executeAsync();

Answer 2

Just make a graph request to me/friends. The SDK already provides you with a convenience method in Request.newMyFriendsRequest
