如何在异步任务中进行 ksoap2 调用?

问题描述

我是安卓开发的新手.我正在尝试开发一个将与 .net webservice 连接以检索数据的应用程序.我想使用 AsyncTask 进行 ksoap2 调用.我如何用 asynctask 调用它asyncronus?

I am a newbie on android development. I am trying to develop an application which will connect with .net webservice in order to retrieve data. I would like to make the ksoap2 call with AsyncTask. How I call it asyncronus with asynctask?

我的 SoapCall 类是

My SoapCall class is

public class SoapCall {

public final static String SOAP_ACTION = "http://www.alpha.net.com/ExecuteEBSCommand";

public final static String OPERATION_NAME = "ExecuteEBSCommand";

public final static String NAMESPACE = "http://www.alpha.net.com";

public final static String URL = "http://192.168.2.100/Ebs2Alpha/Service.asmx";





public String connection(String Command, String CommandParameters) throws Throwable, Throwable {
    String response = null;
    SoapObject Request = new SoapObject(NAMESPACE, OPERATION_NAME);
    Request.addProperty("strCommand", Command);
    Request.addProperty("strCommandParameters", CommandParameters);



    SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
            SoapEnvelope.VER11);
    soapEnvelope.dotNet = true;
    soapEnvelope.setOutputSoapObject(Request);
    // Needed to make the internet call

    // Allow for debugging - needed to output the request

        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        androidHttpTransport.debug = true;
        // this is the actual part that will call the webservice
        androidHttpTransport.call(SOAP_ACTION, soapEnvelope);

        // Get the SoapResult from the envelope body.
        SoapObject result = (SoapObject) soapEnvelope.bodyIn;

        response = result.getProperty(0).toString();


    return response;
    }
}

到目前为止，我通过调用主要活动中的连接方法获得响应

So far I am getting the response by calling the connection method in main activity with

SoapCall  call1= new SoapCall();

call1.connection("get_clients", "%");

推荐答案

使用 AsyncTask 很简单.这是一个例子.

Using AsyncTask is straightforward. Here is an example.

 public class MyTask extends AsyncTask<String, Integer, String>{


    @Override
    protected String doInBackground(String... params) {
    String response = null;
    SoapObject Request = new SoapObject(NAMESPACE, OPERATION_NAME);
    Request.addProperty("strCommand", params[0]);
    Request.addProperty("strCommandParameters", params[1]);



    SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
        SoapEnvelope.VER11);
    soapEnvelope.dotNet = true;
    soapEnvelope.setOutputSoapObject(Request);
    // Needed to make the internet call

    // Allow for debugging - needed to output the request

    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
    androidHttpTransport.debug = true;
    // this is the actual part that will call the webservice
    androidHttpTransport.call(SOAP_ACTION, soapEnvelope);

    // Get the SoapResult from the envelope body.
    SoapObject result = (SoapObject) soapEnvelope.bodyIn;

    response = result.getProperty(0).toString();


    return response;
  }
}

以及对带参数的任务的调用.

And the call to the task with parameters.

MyTask myTask = new MyTask();
myTask.execute(new String[] {Command, CommandParameters});

希望它会有所帮助.
