1、 HYPERLINK /zhangdongzi/archive/2011/04/19/2020688.html Android與服務器端數(shù)據(jù)交互（基于SOAP協(xié)議整合android+webservice）上一節(jié)中我們通過http協(xié)議，采用HttpClient向服務器端action請求數(shù)據(jù)。當然調用服務器端方法獲取數(shù)據(jù)并不止這一種。WebService也可以為我們提供所需數(shù)據(jù)，那么什么是webService呢？，它是一種基于SAOP協(xié)議的遠程調用標準，通過webservice可以將不同操作系統(tǒng)平臺，不同語言，不同技術整合到一起。 我們在PC機器java客戶端中，需要一些庫，比如XFire,Axi

2、s2,CXF等等來支持訪問WebService，但是這些庫并不適合我們資源有限的android手機客戶端，做過JAVA ME的人都知道有KSOAP這個第三方的類庫，可以幫助我們獲取服務器端webService調用，當然KSOAP已經(jīng)提供了基于android版本的jar包了，那么我們就開始吧：首先下載KSOAP包：ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar包然后新建android項目：并把下載的KSOAP包放在android項目的lib目錄下：右鍵-build path-configure build path-選擇Librar

3、ies，如圖：以下分為七個步驟來調用WebService方法：第一：實例化SoapObject 對象，指定webService的命名空間（從相關WSDL文檔中可以查看命名空間），以及調用方法名稱。如：View Code /命名空間privatestaticfinal String serviceNameSpace=http:/WebX/;/調用方法(獲得支持的城市)privatestaticfinal String getSupportCity=getSupportCity;/實例化SoapObject對象 SoapObject request=new SoapObject(serviceNa

4、meSpace, getSupportCity);第二步：假設方法有參數(shù)的話,設置調用方法參數(shù)request.addProperty(參數(shù)名稱,參數(shù)值);第三步：設置SOAP請求信息(參數(shù)部分為SOAP協(xié)議版本號，與你要調用的webService中版本號一致):View Code /獲得序列化的Envelope SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.bodyOut=request;第四步：注冊Envelope,(new MarshalBase6

5、4().register(envelope);第五步：構建傳輸對象，并指明WSDL文檔URL：View Code /請求URLprivatestaticfinal String serviceURL=/webservices/weatherwebservice.asmx;/Android傳輸對象 AndroidHttpTransport transport=new AndroidHttpTransport(serviceURL); transport.debug=true;第六步：調用WebService(其中參數(shù)為1：命名空間+方法名稱，2：Envelope對象):View Code tra

6、nsport.call(serviceNameSpace+getWeatherbyCityName, envelope);第七步：解析返回數(shù)據(jù)：View Code if(envelope.getResponse()!=null)return parse(envelope.bodyIn.toString(); /* * 解析XML * param str * return */privatestatic List parse(String str) String temp; List list=new ArrayList();if(str!=null & str.length()0)int st

7、art=str.indexOf(string);int end=str.lastIndexOf(;); temp=str.substring(start, 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; 這樣就成功啦。那么現(xiàn)在我們就來測試下吧，這里

8、有個地址提供webService天氣預報的服務的，我這里只提供獲取城市列表：View Code /命名空間 private static final String serviceNameSpace=http:/WebX/; /請求URL private static final String serviceURL=/webservices/weatherwebservice.asmx; /調用方法(獲得支持的城市) private static final String getSupportCity=getSupportCity; /調用城市的方法(需要帶參數(shù)) private static

9、final String getWeatherbyCityName=getWeatherbyCityName; /調用省或者直轄市的方法(獲得支持的省份或直轄市) private static final String getSupportProvince=getSupportProvince;然后你可以在瀏覽器中輸入地址（WSDL）：serviceURL,你會看到一些可供調用的方法：我們選擇獲取國內外主要城市或者省份的方法吧：getSupportProvice,然后調用，你會發(fā)現(xiàn)瀏覽器返回給我們的是xml文檔：View Code - 直轄市特別行政區(qū)黑龍江吉林遼寧內蒙古河北河南山東山西江蘇安

10、徽陜西寧夏甘肅青海湖北湖南浙江江西福建貴州四川廣東廣西云南海南新疆西藏臺灣亞洲歐洲非洲北美洲南美洲大洋洲我們可以用 listview來顯示：那么下面我將給出全部代碼：View Code publicclass WebServiceHelper /WSDL文檔中的命名空間privatestaticfinal String targetNameSpace=http:/WebX/;/WSDL文檔中的URLprivatestaticfinal String WSDL=/WebServices/WeatherWebService.asmx?wsdl;/需要調用的方法名(獲得本天氣預報Web Servic
