您还可以使用自定义比较器：
public class CategoriesComparator implements Comparator<Category> {
@Override
public int compare(Category category1, Category category2) {
return category1.getSomeproperty().compareTo(category2.getSomeproperty());
}
}
当您要比较时，请致电：
Collections.sort(yourListCategories, new CategoriesComparator());
希望能帮助到你！
