ListView之排序

 

ArrayList<Trends> list = new ArrayList<Trends>();
		
		for(int i=0;i<5;i++) {
			Trends trends = new Trends();
			trends.setDateCreated(String.valueOf(i));
			trends.setUserName("王武"+i);
			list.add(trends);
		}

Collections.sort(list, new Comparator<Trends>() {
			@Override
			public int compare(Trends object1,
					Trends object2) {
				// TODO Auto-generated method stub
				return object2.getDateCreated()
					.compareTo(object1.getDateCreated()); //倒序
                        //object1.getDateCreated().compareTo(object2.getDateCreated());正序

			}
		});
