Android封装数据请求AsyncHttpClient 和 Volley
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。。
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
