一个带新闻，天气的时钟Widget（三）---Webservices篇

三、新闻和天气是通过webservice来实现

1，天气是请求公共的webservice，新闻自己搭了webservices

关于webservices的请求部分

public static List<String> getWeatherList(String tcity) throws Exception {     String path = "http://www.webxml.com.cn/webservices/weatherwebservice.asmx";     InputStream inStream = WeatherService.class.getClassLoader()             .getResourceAsStream("soap.xml");     String soap =utils.readFile(inStream);         soap = soap.replaceAll("\\$thecity", tcity);     byte[] data = soap.getBytes();

    HttpURLConnection conn = (HttpURLConnection) new URL(path)             .openConnection();     conn.setConnectTimeout(5000);     conn.setRequestMethod("POST");     conn.setDoOutput(true);     conn.setRequestProperty("Content-Type",             "application/soap+xml; charset=utf-8");     conn.setRequestProperty("Content-Length", String.valueOf(data.length));     conn.getOutputStream().write(data);     //Log.d("myout", String.valueOf(conn.getResponseCode()));     if (conn.getResponseCode() == 200) {         return utils.parseXML(conn.getInputStream());     }     return null; }

parseXML完成节点的分析

/**      * 解析返回的SOAP协议      *      * @param inputStream      * @return      */     public static List<String> parseXML(InputStream inputStream) throws Exception {         XmlPullParser parser = Xml.newPullParser();         parser.setInput(inputStream, "UTF-8");        

        List<String> list=new ArrayList<String>();         int eventType = parser.getEventType();         while (eventType != XmlPullParser.END_DOCUMENT) {             if (eventType == XmlPullParser.START_DOCUMENT) {                 System.out.println("Start document:");                             } else if (eventType == XmlPullParser.END_DOCUMENT) {                 System.out.println("End document");             } else if (eventType == XmlPullParser.START_TAG) {                 //System.out.println(" " + parser.getName());                

            } else if (eventType == XmlPullParser.END_TAG) {                 //System.out.println("222 " + parser.getName());             } else if (eventType == XmlPullParser.TEXT) {                 list.add(parser.getText());                                 //System.out.println(" 111" + parser.getText());             }             eventType = parser.next();

        }

        return list;

    }

soap请求的格式，在webserivices服务里有说明

<?xml version="1.0" encoding="UTF-8"?> <soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">   <soap12:Body>     <getWeatherbyCityName xmlns="http://WebXml.com.cn/">       <theCityName>$thecity</theCityName>     </getWeatherbyCityName>   </soap12:Body> </soap12:Envelope>

 

2，新闻部分大同小异了，通过一个listactivity来显示新闻列表，通过一个带webkit的activity来来显示新闻详细的页面

 

详细看代码吧
