问我们如何在android中另一个java类的静态方法中访问activity的ArrayList对象？

EN

public static HashMap<String, List<String>> getData() {

    //here i need access the arraylist object

    HashMap<String, List<String>> expandableListDetail = new HashMap<String, List<String>>();

    List<String>  size = new ArrayList<String>();
    size.add("Regular");
    size.add("Large");

    List<String> Addons = new ArrayList<String>();
    Addons.add("one small cheese");
    Addons.add("chicken");

    expandableListDetail.put("Choice of Size", size);
    expandableListDetail.put("Choice of Add ons", Addons);


    return expandableListDetail;
}
