Android List简单排序（comparator）

public class ListSortingUtils {
    public static List<Details> listSorting(List<Details> listInAppxList) {
       
        Comparator<Details> comparator = new Comparator<Details>() {
            @Override
            public int compare(Details details1, Details details2) {
               //排序规则，按照价格由大到小顺序排列("<"),按照价格由小到大顺序排列(">"),
                if(details1.getPrice() < details2.getPrice())
                    return 1;
                else {
                    return -1;
                }
            }
        };
        //这里就会自动根据规则进行排序
        Collections.sort(listInAppxList, comparator);
        return listInAppxList;
    }
}
