1、 HYPERLINK /zhangdongzi/archive/2011/04/19/2020688.html Android與服務(wù)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(guò)http協(xié)議，采用HttpClient向服務(wù)器端action請(qǐng)求數(shù)據(jù)。當(dāng)然調(diào)用服務(wù)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(yuǎn)程調(diào)用標(biāo)準(zhǔn)，通過(guò)webservice可以將不同操作系統(tǒng)平臺(tái)，不同語(yǔ)言，不同技術(shù)整合到一起。 我們?cè)赑C機(jī)器java客戶端中，需要一些庫(kù)，比如XFire,Axi

2、s2,CXF等等來(lái)支持訪問WebService，但是這些庫(kù)并不適合我們資源有限的android手機(jī)客戶端，做過(guò)JAVA ME的人都知道有KSOAP這個(gè)第三方的類庫(kù)，可以幫助我們獲取服務(wù)器端webService調(diào)用，當(dāng)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(xiàng)目：并把下載的KSOAP包放在android項(xiàng)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(gè)步驟來(lái)調(diào)用WebService方法：第一：實(shí)例化SoapObject 對(duì)象，指定webService的命名空間（從相關(guān)WSDL文檔中可以查看命名空間），以及調(diào)用方法名稱。如：View Code /命名空間privatestaticfinal String serviceNameSpace=http:/WebX/;/調(diào)用方法(獲得支持的城市)privatestaticfinal String getSupportCity=getSupportCity;/實(shí)例化SoapObject對(duì)象 SoapObject request=new SoapObject(serviceNa

4、meSpace, getSupportCity);第二步：假設(shè)方法有參數(shù)的話,設(shè)置調(diào)用方法參數(shù)request.addProperty(參數(shù)名稱,參數(shù)值);第三步：設(shè)置SOAP請(qǐng)求信息(參數(shù)部分為SOAP協(xié)議版本號(hào)，與你要調(diào)用的webService中版本號(hào)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(cè)Envelope,(new MarshalBase6

5、4().register(envelope);第五步：構(gòu)建傳輸對(duì)象，并指明WSDL文檔URL：View Code /請(qǐng)求URLprivatestaticfinal String serviceURL=/webservices/weatherwebservice.asmx;/Android傳輸對(duì)象 AndroidHttpTransport transport=new AndroidHttpTransport(serviceURL); transport.debug=true;第六步：調(diào)用WebService(其中參數(shù)為1：命名空間+方法名稱，2：Envelope對(duì)象):View Code tra

6、nsport.call(serviceNameSpace+getWeatherbyCityName, envelope);第七步：解析返回?cái)?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(lái)測(cè)試下吧，這里

8、有個(gè)地址提供webService天氣預(yù)報(bào)的服務(wù)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(qǐng)求URL private static final String serviceURL=/webservices/weatherwebservice.asmx; /調(diào)用方法(獲得支持的城市) private static final String getSupportCity=getSupportCity; /調(diào)用城市的方法(需要帶參數(shù)) private static

9、final String getWeatherbyCityName=getWeatherbyCityName; /調(diào)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(huì)看到一些可供調(diào)用的方法：我們選擇獲取國(guó)內(nèi)外主要城市或者省份的方法吧：getSupportProvice,然后調(diào)用，你會(huì)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(nèi)蒙古河北河南山東山西江蘇安
