优化列表,大量数据也不会造成卡顿,代码简洁可读性高
使用AutoSwipeRefreshLayout+RecyclerView+通用Adapter(RecyclerView)
这里Adapter是用张鸿洋封装的Adapter 使用方便(这里没有使用到最简化)
##效果图
List有三种数据类型：
1、OrderGoodsInfo 表示每个小订单的头部信息（订单号、订单状态、店铺名称）
2、OrderGoodsItem 表示小订单中的商品
3、OrderPayInfo 表示大订单的支付信息（金额、订单状态）
将列表一个item分成3个部分(布局一般是固定的)
然后通过Adapter根据不同部分来加载不同布局级数据
具体实现:
数据处理:将请求回来的数据赋值到(OrderGoodsInfo,OrderGoodsItem,OrderPayInfo)
public class OrderDataHelper {
/**
* List<Object>有三种数据类型：
* 1、OrderGoodsInfo 表示每个小订单的头部信息（订单号、订单状态、店铺名称）
* 2、OrderGoodsItem 表示小订单中的商品
* 3、OrderPayInfo 表示大订单的支付信息（金额、订单状态）
*
* @param resultList
* @return
*/
public static List<Object> getDataAfterHandle(List<OrderSummary> resultList) {
List<Object> dataList = new ArrayList<Object>();
//遍历每一张大订单
for (OrderSummary orderSummary : resultList) {
//大订单支付的金额核定单状态
OrderPayInfo orderPayInfo = new OrderPayInfo();
orderPayInfo.setTotalAmount(orderSummary.getTotalPrice());
orderPayInfo.setStatus(orderSummary.getStatus());
orderPayInfo.setId(orderSummary.getId());
//小订单商品的
List<OrderGoodsItem> orderDetailList = orderSummary.getOrderDetailList();
Map<String, List<OrderGoodsItem>> orderGoodsMap = new HashMap<String, List<OrderGoodsItem>>();
Map<String, OrderGoodsInfo> orderInfoMap = new HashMap<String, OrderGoodsInfo>();
//遍历每个大订单里面的小订单
for (OrderGoodsItem orderGoodsItem : orderDetailList) {
//获取小订单里面的商铺信息的订单号
String orderCode = orderGoodsItem.getOrder().getOrderCode();
orderGoodsItem.setOrderid(orderSummary.getId());
//拿到相对应订单号的所有商品
List<OrderGoodsItem> goodsList = orderGoodsMap.get(orderCode);
//如果goodsList为空，则新建；而且把这个订单号的orderGoodsMap持有订单的对象goodsList
if (goodsList == null) {
goodsList = new ArrayList<>();
orderGoodsMap.put(orderCode, goodsList);
}
//goodsList添加商品的对象，因为orderGoodsMap已经持有这个订单号的goodsList对象，所以不用重新put
goodsList.add(orderGoodsItem);
//把小订单的店铺信息赋给GoodsOrderInfo对象，并加入到orderInfoMap
OrderGoodsInfo orderInfo = orderInfoMap.get(orderCode);
if (orderInfo == null) {
orderInfo = new OrderGoodsInfo();
orderInfo.setOrderCode(orderCode);
orderInfo.setShopName(orderGoodsItem.getOrder().getShopName());
orderInfo.setStatus(orderGoodsItem.getOrder().getStatus());
orderInfoMap.put(orderCode, orderInfo);
}
}
//把所有数据按照头部、内容和尾部三个部分排序好
Set<String> keySet = orderGoodsMap.keySet();
for (String orderCode : keySet) {
dataList.add(orderInfoMap.get(orderCode));
dataList.addAll(orderGoodsMap.get(orderCode));
}
dataList.add(orderPayInfo);
}
return dataList;
}
}
