How to fill a spinner with content?

guys I'm very new to the Java word, but i share part of the knowledge because of my c# backgroun开发者_运维技巧d, anyways i started developing for android and I'm running into a few snags like the following.

I usually program very OOP so i made all my objects and now i got a very common public class User with things like:

public void setId(long id) {
            this.id = id;
        }

        public long getId() {
            return id;
        }

        public void setFirstName(String firstName) {
            this.firstName = firstName;
        }

        public String getFirstName() {
            return firstName;
        }

and many other properties in it. Also i have a class UserHelper where i have a populated array with all the users been pulled by the queries in the Helper

public ArrayList< User > getCurrentUsers() { return currentUsers; }

well... the thing is, i want to be able to populate a spinner with a the value returned from getFirstName as the Display and getId obviously as the Id. I know exactly how to do this in C# but i been trying to fight with Cursors and doing some reading around but nothing, so i figured that it would be an interesting question.

ANYONE CAN SHOW ME HOW TO DO IT PLEASE?
