利用PinYin4j 实现List中的对象按数字，字母， 汉字排序

要排序的对象：

import net.sourceforge.pinyin4j.PinyinHelper;
import net.sourceforge.pinyin4j.format.HanyuPinyinCaseType;
import net.sourceforge.pinyin4j.format.HanyuPinyinOutputFormat;
import net.sourceforge.pinyin4j.format.HanyuPinyinToneType;
import net.sourceforge.pinyin4j.format.HanyuPinyinVCharType;



public class A implements Comparable<A>{
	private String name;
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	@Override
	public int compareTo(A o) {
		String regex = "^\\w.*";
		if (this.getName().matches(regex) || o.getName().matches(regex)) {
			return this.getName().compareTo(o.getName());
		} else {
			return genPinYin(this.getName()).compareTo(genPinYin(o.getName()));
		}
	}
	public static String genPinYin(String input) {
        if (input == null || input.trim().equals("")) {
            return "";
        }
        HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
        format.setCaseType(HanyuPinyinCaseType.LOWERCASE);
        format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
        format.setVCharType(HanyuPinyinVCharType.WITH_V);
        //多音字预先转换 这里可以处理一下多音字
        char[] chars =  input.trim().toCharArray();
        StringBuilder output = new StringBuilder();
        try {
            for (char c : chars) {
                if (Character.toString(c).matches("[\\u4E00-\\u9FA5]+")) {
                    String[] temp = PinyinHelper.toHanyuPinyinStringArray(c, format);
                    output.append(temp[0]);
                } else {
                    output.append(Character.toString(c));
                }
            }
        } catch (Exception e) {
            System.err.println("拼音转换出现未知异常：" + input);
        }
        return output.toString();
    }
  
}

　　

排序实现：

 

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class Test {

	public static void main(String[] args) {
		A a1 = new A();  A a2 = new A();
		A a3 = new A();  A a4 = new A();
		A a5 = new A();  A a6 = new A();
		A a7 = new A();  A a8 = new A();

		a1.setName("二维码"); a2.setName("回调");
		a3.setName("接口"); a4.setName("服务窗");
		a5.setName("123"); a6.setName("456");
		a7.setName("zbc"); a8.setName("Abhj");
		
		List<A> list = new ArrayList<A>();
		list.add(a1); list.add(a2); list.add(a3); list.add(a4);
		list.add(a5); list.add(a6); list.add(a7); list.add(a8);
		
		Collections.sort(list);
		
		for (A a : list) {
			System.out.println(a.getName());
		}
	}
}
