android list包含字符串,android对list对象中的string字符串进行排序

废话不多说，直接上代码，亲测

public class Person {

public int age;

public String beginTime;

public String name;

public Person(int age, String beginTime, String name) {

super();

this.age = age;

this.beginTime = beginTime;

this.name = name;

}

public Person() {

super();

}

}

public class HahaTime2 {

public static void main(String[] args) {

/**

* 原来的日期

*/

List list = new ArrayList();

list.add(new Person(1,"2016-04-22 15:30:28", "小芳"));

list.add(new Person(1,"2016-03-02 15:30:28", "小花"));

list.add(new Person(1,"2016-02-12 15:30:28", "小狗"));

list.add(new Person(1,"2016-12-02 15:30:28", "小猫"));

list.add(new Person(1,"2016-02-02 15:30:28", "小米"));

list.add(new Person(1,"2016-02-12 15:30:28", "小明"));

Collections.sort(list, new MapComparator());

for (Person person : list) {

System.out.println(person.name+";"+person.beginTime);

}

}

}

class MapComparator implements Comparator{

public int compare(Person lhs, Person rhs) {

return lhs.beginTime.compareTo(rhs.beginTime);

}

}
