AsyncHttpClient使用示例代碼

實現http異步請求get,post請求，也可以用作文件上傳。 下面是登錄的示例

    AsyncHttpClient client = new AsyncHttpClient();


                    RequestParams params = new RequestParams();  

                    params.add("RequestType", "");  
                    params.add("UserID", "-1");  
                    params.add("NurseID", "-1");  
                    params.add("HospitalId", "-1");  

                    JSONObject jsonObject = new JSONObject();  
                    try {  
                        jsonObject.put("UserCode", username);  
                        jsonObject.put("Password", password);  
                    } catch (JSONException e) {  
                        // TODO Auto-generated catch block  
                        e.printStackTrace();  
                    }  

                    params.add("RequestParam", jsonObject.toString());  

                    client.get(path, params, new TextHttpResponseHandler() {  

                        @Override  
                        public void onSuccess(int statusCode, Header[] headers,  
                                String responseString) {  
                            // TODO Auto-generated method stub  
                            if (statusCode == 200) {  

                                // Toast.makeText(getApplicationContext(),  
                                // responseString, Toast.LENGTH_SHORT)  
                                // .show();  
                                            Intent intent = new Intent();  
                                            intent.setClass(  
                                                    getApplicationContext(),  
                                                    MainActivity.class);  
                                            startActivity(intent);  
                                        } else {  
                                            Intent intent = new Intent();  
                                            intent.setClass(

                                                    MainActivity.class);  
                                            startActivity(intent);  
                                        }  

                                    } else {  
                                        Toast.makeText(getApplicationContext(),

                                    e.printStackTrace();  
                                }  
                            }else {  
                                Toast.makeText(getApplicationContext(),  
                                        "網絡連接超時", Toast.LENGTH_SHORT).show();  
                            }  
                        }  

                        @Override  
                        public void onFailure(int statusCode, Header[] headers,  
                                String responseString, Throwable throwable) {  
                            // TODO Auto-generated method stub  
                            Toast.makeText(getApplicationContext(),  
                                    responseString, Toast.LENGTH_SHORT).show();  
                        }  </pre> 


 1.聲明一個client對象，初始化
 2.根據需要調用client中get,post請求 

 3，重寫onSuccess（）和onFailure（）方法
