实现集合的排序功能

Collections.sort(myData, sDisplayNameComparator);
        return myData;
    }

    private final static Comparator<Map<String, ?>> sDisplayNameComparator = new Comparator<Map<String, ?>>() {
        private final Collator collator = Collator.getInstance();

        public int compare(Map<String,?> map1, Map<String,?> map2) {
            return collator.compare(map1.get("title"), map2.get("title"));
        }
    };
