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());
}
}
}
