Android获得火车时刻表Web Services的全部始发站名称

        尽量写的简单些，希望对大家有所帮助。

        一、下载 KSOAP2 包地址： http://code.google.com/p/ksoap2-android/source/browse/m2-repo/com/google/code/ksoap2-android/ksoap2-android-assembly/2.5.4/ksoap2-android-assembly-2.5.4-jar-with-dependencies.jar ，点击右下角的 View raw file 链接下载。

        二、将 KSOAP2 包添加到 Eclipse 中，右键单击我们需要添加 KSOAP2 包的工程——>单击 "Build Path" ——>单击 "Configure Build Path..." 。添加成功如图所示：

 

 

 

        三、怎样去调用 WebService 中的方法，代码实现如下：

package com.treasure.train.transport;import java.io.IOException;import java.util.ArrayList;import java.util.List;import org.ksoap2.SoapEnvelope;import org.ksoap2.serialization.SoapObject;import org.ksoap2.serialization.SoapSerializationEnvelope;import org.ksoap2.transport.HttpTransportSE;import org.xmlpull.v1.XmlPullParserException;import com.treasure.train.meta.Constant;public class WebServiceHelper {/** * 获得所有始发站的城市名称 * @return */public static List<String> getAllStartStationCityNames(){List<String> cityNames = new ArrayList<String>();SoapObject soapObject = new SoapObject(Constant.URL, Constant.getStationName);SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);envelope.bodyOut = soapObject;envelope.dotNet = true;envelope.setOutputSoapObject(soapObject);HttpTransportSE httpTranstation = new HttpTransportSE(Constant.URL);httpTranstation.debug = true;try {httpTranstation.call(Constant.SOAP_ACTION, envelope);SoapObject result = (SoapObject)envelope.getResponse();// 下面对结果进行解析。int count = result.getPropertyCount();for (int index = 0; index < count; index++){cityNames.add(result.getProperty(index).toString());}} catch (IOException e) {e.printStackTrace();} catch (XmlPullParserException e) {e.printStackTrace();}return cityNames;}}

 

        Constant.java, 代码如下：

package com.treasure.train.meta;public class Constant {// 命名空间public static final String NAMESPACE = "http://WebXml.com.cn/";// 获得本火车时刻表Web Service 的全部始发站名称public static final String getStationName = "getStationName";// 请求URLpublic static final String URL = "http://www.webxml.com.cn/WebServices/TrainTimeWebService.asmx";// 用于调用WebService,形式是：命名空间+方法名称（参数1）public static final String SOAP_ACTION = "http://WebXml.com.cn/getStationName";}

        四、最后在 AndroidManifest.xml 加入访问 Internet 权限。代码如下：

<uses-permission android:name="android.permission.INTERNET"/>
