Android/Java汉字按照拼音排序

汉字排序之前:

        peopleList.add(new NameBean("风四娘"));
        peopleList.add(new NameBean("连城璧"));
        peopleList.add(new NameBean("萧十一郎 "));
        peopleList.add(new NameBean("沈璧君"));
        peopleList.add(new NameBean("逍遥侯"));
        peopleList.add(new NameBean("杨开泰"));
        peopleList.add(new NameBean("沈飞云"));
        peopleList.add(new NameBean("小公子"));

汉字排序之后:

 PeopleList: 0==风四娘
 PeopleList: 1==连城璧
 PeopleList: 2==沈璧君
 PeopleList: 3==沈飞云
 PeopleList: 4==小公子
 PeopleList: 5==萧十一
 PeopleList: 6==逍遥侯
 PeopleList: 7==杨开泰

特性:

1 可以自定义多音字词典,避免”重庆”变成”ZHONGQING”
2 灵活易懂,读者可以根据需要自行修改排序规则

在使用这个Util之前Android请加上这句话:

compile ‘com.github.promeg:tinypinyin:2.0.3’

public class NameBean{
    public String nameChinese;//汉字: 梁超杰
    public String firstLetter;//首字母:  L
    public String namePinYin;//拼音:  LIANGCHAOJIE
    public NameBean(String name) {
        this.nameChinese = name;
        this.namePinYin = Pinyin.toPinyin(name, "");
        firstLetter = namePinYin.substring(0,1);
    }
}

import java.util.List;

/**
 * @Description: 对汉字进行排序

public class ChineseSortUtil {
    public static void sortList(List list){
        transferList(list);
    }

    /**
     * 进行冒泡排序
     * @param list
     */
    private static void transferList(List list) {
        for (int i=0;i1;i++){
            for (int j = 0; j < list.size() -1- i; j++) {
                exchangeNameOrder(j,list);
            }
        }
    }

    /**
     * 交换两个名字的顺序,根据首字母判断
     * @param j
     * @param list
     */
    private static void exchangeNameOrder(int j, List list) {
        String namePinYin1 = list.get(j).namePinYin;
        String namePinYin2 = list.get(j+1).namePinYin;

        int size = namePinYin1.length() >= namePinYin2.length() ? namePinYin2.length() : namePinYin1.length();
        for (int i=0;ichar jc = namePinYin1.charAt(i);
            char jcNext = namePinYin2.charAt(i);
            if(jc//A在B之前就不用比较了
                break;
            }
            if(jc>jcNext){//A在B之后就直接交换,让A在前面B在后面
                NameBean nameBean=list.get(j);
                list.set(j , list.get(j+1));
                list.set(j + 1, nameBean);
                break;
            }
            //如果AB一样就继续比较后面的字母
        }
    }
}

使用举例:

/**
 * 对联系人进行排序
 */
public class MainActivity extends AppCompatActivity {

    private List peopleList;//联系人列表
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initPeopleList();
        ChineseSortUtil.sortList(peopleList);
        showPeopleList(peopleList);
    }

    private void showPeopleList(List list) {
        for (int i=0;i"TAG", "PeopleList: "+i+"=="+list.get(i).nameChinese);
        }
    }

    private void initPeopleList() {
        peopleList = new ArrayList<>();
        peopleList.add(new NameBean("风四娘"));
        peopleList.add(new NameBean("连城璧"));
        peopleList.add(new NameBean("萧十一郎 "));
        peopleList.add(new NameBean("沈璧君"));
        peopleList.add(new NameBean("逍遥侯"));
        peopleList.add(new NameBean("杨开泰"));
        peopleList.add(new NameBean("沈飞云"));
        peopleList.add(new NameBean("小公子"));
    }

}
