1.Android-async-http的Get和Post请求的使用

public class MainActivity extends ActionBarActivity {  5 
 @Override  7     protected void onCreate(Bundle savedInstanceState) {  8         super.onCreate(savedInstanceState);  9  setContentView(R.layout.activity_main); 10         // asynchttpGet();
 asynchttpPost(); 12  } 13 
    // --------------------Post()方式请求网络---------------------------------------------
    private void asynchttpPost() { 16 
        String url = "http://apis.juhe.cn/mobile/get?"; 18         AsyncHttpClient client = new AsyncHttpClient(); 19         RequestParams params = new RequestParams(); 20         params.put("phone", "13666666666"); 21         params.put("key", "335adcc4e891ba4e4be6d7534fd54c5d"); 22         client.post(url, params, new AsyncHttpResponseHandler() { 23  @Override 24             public void onSuccess(String content) { 25                 // TODO Auto-generated method stub
                super.onSuccess(content); 27                 Toast.makeText(MainActivity.this, content, 1).show(); 28  } 29 
 @Override 31             public void onFailure(Throwable error) { 32                 // TODO Auto-generated method stub
                super.onFailure(error); 34                 Toast.makeText(MainActivity.this, "请求失败", 1).show(); 35  } 36 
 }); 38 
 } 40 
    // --------------------Get()方式请求网络---------------------------------------------
    private void asynchttpGet() { 43         AsyncHttpClient client = new AsyncHttpClient(); 44         String url = "http://apis.juhe.cn/mobile/get?phone=13666666666&key=335adcc4e891ba4e4be6d7534fd54c5d"; 45         client.get(url, new AsyncHttpResponseHandler() { 46 
 @Override 48             public void onSuccess(String content) { 49                 // TODO Auto-generated method stub
                super.onSuccess(content); 51                 Toast.makeText(MainActivity.this, content, 1).show(); 52  } 53 
 @Override 55             public void onFailure(Throwable error) { 56                 // TODO Auto-generated method stub
                super.onFailure(error); 58                 Toast.makeText(MainActivity.this, "请求失败", 1).show(); 59  } 60  }); 61 
 } 63 
}

 

 

2.Android-async-http回调逻辑的二次封装

public class RequestUtils {  2 
    public static AsyncHttpClient client=new AsyncHttpClient();  4     public static void ClientGet(String url, NetCallBack cb) {  5  client.get( url, cb);  6  }  7     

    public static void ClientPost(String url, RequestParams params,NetCallBack cb) { 10  client.post(url,params, cb); 11  } 12 }

 

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