Android之ksoap2-android详解与调用天气预报Webservice完整实例_移动开发_编程开发_程序员俱乐部

Google为Android平台开发Web Service客户端提供了ksoap2-android项目，在这个网址下载开发包http://code.google.com/p/ksoap2-android/source/browse/m2-repo/com/google/code/ksoap2-android/ksoap2-android-assembly/3.1.0/ksoap2-android-assembly-3.1.0-jar-with-dependencies.jar

使用 kspoap2-android调用webserice操作的步骤如下：

  1、创建HttpTransportSE传输对象 传入webservice服务器地址

class="dp-j" start="1">
1. final HttpTransportSE httpSE = new HttpTransportSE(SERVER_URL);  

  2、 创建SoapObject对象，创建该对象时需要传入所要调用Wb Service的命名空间、Web Service方法名；如果有参数要传给Web Service服务器，调用SoapObject对象的addProperty(String name,Object value)方法来设置参数，该方法的name参数指定参数名；value参数指定参数值

1. SoapObject soapObject = new SoapObject(PACE, M_NAME);  

1. soapObject.addProperty("byProvinceName ", citys);  

3、创建SoapSerializationEnelope对象，并传入SOAP协议的版本号；并设置对象的bodyOut属性

1. final SoapSerializationEnvelope soapserial = new SoapSerializationEnvelope(  
2.             SoapEnvelope.VER11);  
3.     soapserial.bodyOut = soapObject;  
4.     // 设置与.NET提供的Web service保持有良好的兼容性  
5.     soapserial.dotNet = true;  

  6、调用HttpTransportSE对象的call()方法，其中call的第一个参数soapAction，第二个为SoapSerializationEvelope对象 调用远程Web Service；

1. // 调用HttpTransportSE对象的call方法来调用 webserice  
2.    httpSE.call(PACE + M_NAME, soapserial);  

   7、获取返回的信息,并解析

1. // 获取服务器响应返回的SOAP消息  
2. SoapObject result = (SoapObject) soapserial.bodyIn;  
3. SoapObject detail = (SoapObject) result.getProperty("getSupportProvinceResult");  
4. //解析返回信息  
5. for (int i = 0; i < detail.getPropertyCount(); i++) {  
6. citys.add(detail.getProperty(i).toString());  
7. }
