Set Type of ArrayList Dynamically

Currently I have this set of code:

package com.sdqn.shared.property;

import java.util.ArrayList;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Misc_ReturnValue {
    public String message;
    public int total;
    public boolean success;
    public ArrayList results;

    public Misc_ReturnValue(){
        this.success = false;
        this.total = 0;
    }
}

The problem is, I need the results to accept any type. I try to follow the answer from here but it seem like I don't understand how to use it in my code. Can anybody explain to me how I can achieve this?
