1、Android与服务器端数据交互（基于SOAP协议整合android+webservice） 上一节中我们通过http协议，采用HttpClient向服务器端action请求数据。当然调用服务器端方法获取数据并不止这一种。WebService也可以为我们提供所需数据，那么什么是webService呢？，它是一种基于SAOP协议的远程调用标准，通过webservice可以将不同操作系统平台，不同语言，不同技术整合到一起。 我们在PC机器java客户端中，需要一些库，比如XFire,Axis2,CXF等等来支持访问WebService，但是这些库并不适合我们资源有限的android手机客户端，做过
2、JAVA ME的人都知道有KSOAP这个第三方的类库，可以帮助我们获取服务器端webService调用，当然KSOAP已经提供了基于android版本的jar包了，那么我们就开始吧：首先下载KSOAP包：ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar包然后新建android项目：并把下载的KSOAP包放在android项目的lib目录下：右键-build path-configure build path-选择Libraries，如图：以下分为七个步骤来调用WebService方法：第一：实例化SoapObject 对象，指定we
3、bService的命名空间（从相关WSDL文档中可以查看命名空间），以及调用方法名称。如：View Code /命名空间 private static final String serviceNameSpace=http:/WebX /调用方法(获得支持的城市) private static final String getSupportCity=getSupportCity;/实例化SoapObject对象 SoapObject request=new SoapObject(serviceNameSpace, getSupportCity);第二步：假设方法有参数的话,设置调用方法参数req
4、uest.addProperty(参数名称,参数值);第三步：设置SOAP请求信息(参数部分为SOAP协议版本号，与你要调用的webService中版本号一致):View Code /获得序列化的Envelope SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.bodyOut=request;第四步：注册Envelope,(new MarshalBase64().register(envelope);第五步：构建传输对象，并指明WSDL文档URL：Vie
5、w Code /请求URL private static final String serviceURL=/Android传输对象 AndroidHttpTransport transport=new AndroidHttpTransport(serviceURL); transport.debug=true;第六步：调用WebService(其中参数为1：命名空间+方法名称，2：Envelope对象):View Code transport.call(serviceNameSpace+getWeatherbyCityName, envelope);第七步：解析返回数据：View Code i
6、f(envelope.getResponse()!=null) return parse(envelope.bodyIn.toString(); /* * 解析XML * param str * return */ private static List parse(String str) String temp; List list=new ArrayList(); if(str!=null & str.length()0) int start=str.indexOf(string); int end=str.lastIndexOf(;); temp=str.substring(start,
7、 end-3); String test=temp.split(;); for(int i=0;itest.length;i+) if(i=0) temp=testi.substring(7); else temp=testi.substring(8); int index=temp.indexOf(,); list.add(temp.substring(0, index); return list; 这样就成功啦。那么现在我们就来测试下吧，这里有个地址提供webService天气预报的服务的，我这里只提供获取城市列表：View Code /命名空间 private static final
8、String serviceNameSpace=http:/WebX /请求URL private static final String serviceURL= /调用方法(获得支持的城市) private static final String getSupportCity=getSupportCity; /调用城市的方法(需要带参数) private static final String getWeatherbyCityName=getWeatherbyCityName; /调用省或者直辖市的方法(获得支持的省份或直辖市) private static final String get
9、SupportProvince=getSupportProvince;然后你可以在浏览器中输入地址（WSDL）：serviceURL,你会看到一些可供调用的方法：我们选择获取国内外主要城市或者省份的方法吧：getSupportProvice,然后调用，你会发现浏览器返回给我们的是xml文档：View Code - ArrayOfString xmlns:xsi=http:/www.w3.org/2001/XMLSchema-instance xmlns:xsd=http:/www.w3.org/2001/XMLSchema xmlns=http:/WebX 直辖市 特别行政区 黑龙江 吉林 辽
