Tecent:android端AysncHttpClient使用

 

HttpManager封装

 1 public void sendRequest(String url, Map<String,String> headers,Map<String, String> params,
 2             final ObjectCallback<Object> callback) {
 3         AsyncHttpClient client = new AsyncHttpClient();

ObjectCallback

 1 public abstract class ObjectCallback<T> {

 8                 .getGenericSuperclass();
 9         clazz = (Class<T>) type.getActualTypeArguments()[0];
10     }
11 
12     public Class<T> getDataClass() {
13         return clazz;
14     }
15 
16     public abstract void onSuccess(T data);
17 
18     public abstract void onFailure(int errorCode, String errorString);
19 }
