问如何在parse android中进行连接查询

EN

   "you must create a separate table in which the relationship is tracked. 
   This table, which we will call Favourite, would have a 'User_Id'
   column and a 'Favourite_Id' column, each with a pointer to a Parse User."



    currentUser = ParseUser.getCurrentUser();

    ParseQuery<ParseObject> query = ParseQuery.getQuery("Favourite");
    query.whereEqualTo("User_Id", currentUser);
    query.findInBackground(new FindCallback<ParseObject>() {
        public void done(List<ParseObject> objectList, ParseException e) {
            if (e == null) {
                userList = new ArrayList<ParseObject>();
                parseUsers = new ArrayList<ParseUser>();
                for (int i = 0; i < objectList.size(); i++) {
                    userList.add((ParseObject) objectList.get(i).get("Favourite_Id"));
                }
                for (int i = 0; i < userList.size(); i++) {
                    userList.get(i).fetchIfNeededInBackground(new GetCallback<ParseUser>() {
                        @Override
                        public void done(ParseUser object, ParseException e) {
                            if (e == null) {
                                parseUsers.add(object);
                            }
                        }
                    });
                }


            }

        }
    });
