Android封装数据请求AsyncHttpClient 和 Volley

标签：

将 AsyncHttpClient 和 Volley 的jar导入的libs目录下面，

导入遇见的问题，导入后到时没有对应的类，，解决方法，在你导入的包下面右击点击add to Library。。就可以了。是不是很菜啊。我菜我快乐。。

技术分享

1 NetRequest 封装的数据请求，，跟加载图片

2 NetUtil 配置请求数据。。

3 macro 存放的是宏。。

4 HomepageGross 跟 HomepageRollAndData是数据model，

5 RequestResultModel 请求数据结果

6 RequestResultUtil 处理请求的数据

感觉封装完简单了很多，有没有。

 1 开始请求
 2  Map routeDict =new HashMap();
 3         routeDict.put(DataRequestMacro.kFunction,DataRequestMacro.kHomepageRoll);
 4         routeDict.put(DataRequestMacro.kCHomepageIndex,DataRequestMacro.kClass);
 5         JSONObject routeStr = new JSONObject(routeDict);
 6 
 7         Map dataDict = new HashMap();
 8         dataDict.put(DataRequestMacro.kHomepageCity, "北京");
 9         JSONObject  dataStr = new JSONObject(dataDict);
10         
11         NetUtil.post_request_Json(DataRequestMacro.kTagHomePageRoll, this, DataRequestMacro.kRequestUrlstr, NetUtil.params_route_data(routeDict, dataDict), this);
12 
13 请求完数据回调。。。。
14 @Override
15     public void request_back_result(RequestResultModel model){
16         System.out.println("回调~~~~~~~~~~~~~~~~~~"+model.requestTag+model.resultCode);
17     }

开发IOS的刚开发Android 有什么不对的，你有什么更好的call me。一同进步。。谢谢
