Android 按属性对 arraylist 进行排序

如何 ，并添加案例代码来解释如何根据Android中的属性对ArrayList进行排序？

java
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
public class MainActivity {
    public static void main(String[] args) {
        // 创建一个包含Person对象的ArrayList
        ArrayList personList = new ArrayList<>();
        personList.add(new Person("Alice", 25));
        personList.add(new Person("Bob", 30));
        personList.add(new Person("Charlie", 20));
        // 根据年龄属性对ArrayList进行排序
        Collections.sort(personList, new Comparator() {
            @Override
            public int compare(Person person1, Person person2) {
                return person1.getAge() - person2.getAge();
            }
        });
        // 打印排序后的结果
        for (Person person : personList) {
            System.out.println(person.getName() + ", " + person.getAge());
        }
    }
    static class Person {
        private String name;
        private int age;
        public Person(String name, int age) {
            this.name = name;
            this.age = age;
        }
        public String getName() {
            return name;
        }
        public int getAge() {
            return age;
        }
    }
}
