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
