实现数据根据日期倒序排列
(1).在JavaBean中实现Comparable＜Bean＞接口，重写hashCode()、equals(Object obj)、 compareTo(PriceBean another)方法：

@Overridepublic int compareTo(PriceBean another) { if (another instanceof PriceBean) {  PriceBean priceBean = (PriceBean) another;  int comOfferday = priceBean.offerday.compareTo(this.offerday);  return comOfferday; } return 0;}

(2).在用到排序集合的地方：

 ArrayList<PriceBean> mContentList = new ArrayList<PriceBean>(); LogMessage.i("monkey", "价格排序前-->" + mContentList.toString()); Collections.sort(mContentList); LogMessage.i("monkey", "价格排序后-->" + mContentList.toString());
