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"));
}
};
