java反射呼叫支付SDK(2)

6. 如何捕获回调接口CarrotPayCallbackMethodInterceptor类实现返回的参数

    public class CarrotPayCallbackMethodInterceptor implements InvocationHandler {  
        CarrotPaySdkFinal csf;  
        public CarrotPayCallbackMethodInterceptor (CarrotPaySdkFinal paytype){  
            csf = paytype;  
        }  
        @Override  
        public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {  
            // TODO Auto-generated method stub  
            switch (csf) {  
            case CMCC_PAY:  
                    //在这里获得回调函数返回的参数，通过自定义carrotSdkHelper发送给callback处理返回结果  
                              for(int j = 0; j < args.length;j++){  
                    if(args[j].getClass().getName().equalsIgnoreCase("java.lang.Integer")){  
                        Integer result = (Integer)args[j];  
                        switch (result) {  
                        case 1:  
                            Message msg_cmcc_success = new Message();  
                            msg_cmcc_success.what = CarrotPaySDK.CARROT_PAY_SUCCESS;  
                            CarrotPaySDK.carrotSdkHleper.cmcc_PayendHandler.sendMessage(msg_cmcc_success);  
                            break;  
                        case 2:  
                            Message msg_cmcc_faild = new Message();  
                            msg_cmcc_faild.what = CarrotPaySDK.CARROT_PAY_FAILD;  
                            CarrotPaySDK.carrotSdkHleper.cmcc_PayendHandler.sendMessage(msg_cmcc_faild);  
                            break;  
                        default:  
                            Message msg_cmcc_faild2 = new Message();  
                            msg_cmcc_faild2.what = CarrotPaySDK.CARROT_PAY_FAILD;  
                            CarrotPaySDK.carrotSdkHleper.cmcc_PayendHandler.sendMessage(msg_cmcc_faild2);  
                            break;  
                        }  
                    }  
                }  
                break;  
            case OTHER_PAY:  
                Log.e("___________OTHER_______________", "____________________"+method.getName());  
                  
                for(int j = 0; j < args.length;j++){  
                    Log.e("___________OTHER_______________"+args[j].getClass().getName(), "____________________"+args[j].toString());  
                      
                }  
                Log.e("___________OTHER_______________", "______333333______________");  
                break;  
            default:  
                break;  
            }  
              
            return null;    
        }  
      
    }  

7. （1）回调类的介绍

    public interface CarrotPayCallBack {    
            public void onPayEnd(int isSuccess);    
        }   

（2）创建一个新的CarrotPayCallBack并将其传递给4步方法

    new CarrotPayCallBack() {  
                      
                    @Override  
                    public void onPayEnd(int isSuccess) {  
                        // TODO Auto-generated method stub  
                        switch (isSuccess) {  
                        case CarrotPaySDK.CARROT_PAY_SUCCESS:  
                            Toast.makeText(getApplicationContext(), "支付成功", Toast.LENGTH_SHORT).show();  
                            break;  
                        case CarrotPaySDK.CARROT_PAY_CANCEL:  
                            Toast.makeText(getApplicationContext(), "支付取消", Toast.LENGTH_SHORT).show();  
                            break;  
                        case CarrotPaySDK.CARROT_PAY_FAILD:  
                            Toast.makeText(getApplicationContext(), "支付失败", Toast.LENGTH_SHORT).show();  
                            break;  
                        case CarrotPaySDK.CARROT_PAY_UNKNOW:  
                            Toast.makeText(getApplicationContext(), "未知错误", Toast.LENGTH_SHORT).show();  
                            break;  
                        default:  
                            break;  
                        }  
                    }  
                }
