18         AsyncHttpClient client = new AsyncHttpClient();
19         RequestParams params = new RequestParams();
20         params.put("phone", "13666666666");

2.Android-async-http回调逻辑的二次封装

 1 public class RequestUtils {
 2
 3     public static AsyncHttpClient client=new AsyncHttpClient();
 4     public static void ClientGet(String url, NetCallBack cb) {
 5         client.get( url,  cb);
 6     }
 7
 8
 9     public static void ClientPost(String url, RequestParams params,NetCallBack cb) {
10         client.post(url,params, cb);
11     }
12 }

 1 public abstract class NetCallBack extends AsyncHttpResponseHandler {
 2     @Override
 3     public void onStart() {
 4         // TODO Auto-generated method stub
 5         super.onStart();
 6
 7         System.out.println("--->>请求开始，弹出进度条");
 8     }
 9
10     @Override
11     public void onSuccess(String content) {
12         // TODO Auto-generated method stub
13         super.onSuccess(content);
14         onMySuccess(content);
15         System.out.println("--->>请求Success，隐藏进度条" + content);
16     }
17
18     @Override
19     public void onFailure(Throwable error) {
20         // TODO Auto-generated method stub
21         super.onFailure(error);
22         onMyFailure(error);
23         System.out.println("--->>Failure");
24     }
25
26     public abstract void onMySuccess(String result);
27
28     public abstract void onMyFailure(Throwable error);
29 }
