Android[項目] Android天氣預報

這個項目是基於webservice的,用ksoap2來解析網路上的WebService的,我們先看做出的

其實也沒有很多技術難題,我們直接來看源碼再做說明吧

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;public class WebServiceUtil{// 定義Web Service的命名空間static final String SERVICE_NS = "http://WebXml.com.cn/";// 定義Web Service提供服務的URLstatic final String SERVICE_URL = "http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx";/** * 獲得州，國內外省份和城市資訊 *  * @return */public static List<String> getProvinceList(){// 需要調用的方法名(獲得本天氣預報Web Services支援的洲、國內外省份和城市資訊)String methodName = "getRegionProvince";// 建立HttpTransportSE傳輸對象HttpTransportSE httpTranstation = new HttpTransportSE(SERVICE_URL);httpTranstation.debug = true;// 使用SOAP1.1協議建立Envelop對象SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);// 執行個體化SoapObject對象SoapObject soapObject = new SoapObject(SERVICE_NS, methodName);envelope.bodyOut = soapObject;// 設定與.Net提供的Web Service保持較好的相容性envelope.dotNet = true;try{// 調用Web ServicehttpTranstation.call(SERVICE_NS + methodName, envelope);if (envelope.getResponse() != null){// 擷取伺服器響應返回的SOAP訊息SoapObject result = (SoapObject) envelope.bodyIn;SoapObject detail = (SoapObject) result.getProperty(methodName+ "Result");// 解析伺服器響應的SOAP訊息。return parseProvinceOrCity(detail);}} catch (Exception e){e.printStackTrace();}return null;}/** * 根據省份擷取城市列表 *  * @param province * @return */public static List<String> getCityListByProvince(String province){// 需要調用的方法名(獲得本天氣預報Web Services支援的城市資訊,根據省份查詢城市集合：帶參數)String methodName = "getSupportCityString";HttpTransportSE httpTranstation = new HttpTransportSE(SERVICE_URL);httpTranstation.debug = true;SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);SoapObject soapObject = new SoapObject(SERVICE_NS, methodName);soapObject.addProperty("theRegionCode", province);envelope.bodyOut = soapObject;envelope.dotNet = true;try{// 調用Web ServicehttpTranstation.call(SERVICE_NS + methodName, envelope);if (envelope.getResponse() != null){// 擷取伺服器響應返回的SOAP訊息SoapObject result = (SoapObject) envelope.bodyIn;SoapObject detail = (SoapObject) result.getProperty(methodName+ "Result");// 解析伺服器響應的SOAP訊息。return parseProvinceOrCity(detail);}} catch (Exception e){e.printStackTrace();}return null;}private static List<String> parseProvinceOrCity(SoapObject detail){ArrayList<String> result = new ArrayList<String>();for (int i = 0; i < detail.getPropertyCount(); i++){String str = detail.getProperty(i).toString();// 解析出每個省份result.add(str.split(",")[0]);}return result;}public static SoapObject getWeatherByCity(String cityName){// 根據城市或地區名稱查詢獲得未來三天內天氣情況、現在的天氣實況、天氣和生活指數String methodName = "getWeather";HttpTransportSE httpTranstation = new HttpTransportSE(SERVICE_URL);httpTranstation.debug = true;SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);SoapObject soapObject = new SoapObject(SERVICE_NS, methodName);soapObject.addProperty("theCityCode", cityName);envelope.bodyOut = soapObject;envelope.dotNet = true;try{// 調用Web ServicehttpTranstation.call(SERVICE_NS + methodName, envelope);if (envelope.getResponse() != null){// 擷取伺服器響應返回的SOAP訊息SoapObject result = (SoapObject) envelope.bodyIn;SoapObject detail = (SoapObject) result.getProperty(methodName+ "Result");// 解析伺服器響應的SOAP訊息。return detail;}} catch (Exception e){e.printStackTrace();}return null;}}

 這裡面有三個方法,分別解析了省份,城市,還有就是天氣情況資料,這裡面就採用了WebService來進行資料互動

接下來就是Activity中的代碼:

 這裡面也只是一些資料有整理和匯總,主要是希望讀者能夠學習如何使用Ksoap2這個類,代碼裡的注釋也寫的很清楚了.其實如果想做出好的應用的話就應該學會如何利用網路資源來跟自己的應用互動,畢竟網路資源是無窮的,像XML解析之類的,你也可以解析團購網站的XML檔案,呵呵,下一個項目就解析XML檔案了,呵呵,這裡就說到這裡吧
