本篇文章，对中文的排序规则为：首个汉字——拼音——首字母，遵循26个英文字母的顺序排列

[java]

import java.text.Collator;

import java.util.ArrayList;

import java.util.Collections;

import java.util.Comparator;

import java.util.HashMap;

import java.util.List;

import java.util.Locale;

import java.util.Map;

import org.apache.commons.collections.MapUtils;

public class ListSort {

public static void main(String[] args) {

List<Map<String, Object>> list=new ArrayList<Map<String,Object>>();

Map<String, Object> map=new HashMap<String, Object>();

map.put("name", "中国");

Map<String, Object> map1=new HashMap<String, Object>();

map1.put("name", "美国");

Map<String, Object> map2=new HashMap<String, Object>();

map2.put("name", "俄罗斯");

Map<String, Object> map3=new HashMap<String, Object>();

map3.put("name", "英国");

list.add(map);

list.add(map1);

list.add(map2);

list.add(map3);

System.out.println("排序前："+list);

listSort(list);

System.out.println("排序后："+list);

}

public static void listSort(List<Map<String, Object>> resultList) {

Collections.sort(resultList, new Comparator<Map<String, Object>>() {

public int compare(Map<String, Object> o1, Map<String, Object> o2) {

String name1=MapUtils.getString(o1, "name");

String name2=MapUtils.getString(o2, "name");

Collator instance = Collator.getInstance(Locale.CHINA);

return instance.compare(name1, name2);

}

});

}

}

结果：
