首先，WebService进年来的使用人数很多了，它可以是一套接口多端调用，返回的格式是JSON和XML。在项目中使用的，可以分为如下的四个步骤：
1.下载ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar文件
2.开始创建HttpTransportSE 对象
3.使用Soap1.1的协议创建SoapSerializationEnvelope
4.创建SoapObject对象
5.设置与.NET提供的Web Service 保存更好的兼容
6.调用Web Service
7.处理返回结果，解析数据。
下面是我的源码：
(1)WebServiceUtil.java
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import java.util.concurrent.Callable;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.FutureTask;
/**

*/
public class WebServiceUtil {
public static SoapObject getData(String service_url, final String service_ns, final String methodName){
/**
* 创建HttpTransportSE 对象
*/
final HttpTransportSE ht = new HttpTransportSE(service_url);
ht.debug = true;
/**
* 使用Soap1.1的协议创建EEnvelope
*/
final SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
/**
*创建SoapObject对象
*/
SoapObject soapObject = new SoapObject(service_ns,methodName);
envelope.bodyOut =soapObject;
/***
* 设置与.NET提供的Web Service 保存更好的兼容
*/
envelope.dotNet = true;
FutureTask<SoapObject> task = new FutureTask<SoapObject>(new Callable<SoapObject>() {
@Override
public SoapObject call() throws Exception {
//调用Web Service
ht.call(service_ns+methodName,envelope);
if (envelope.getResponse()!=null){
//获取服务器返回的结果
SoapObject result = (SoapObject) envelope.bodyIn;
return result;
}
return null;
}
});
new Thread(task).start();
try {
return task.get();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
return null;
}
}
