在网上发现一个接口，是关于航班查询的，http://webservice.webxml.com.cn/webservices/DomesticAirline.asmx ，而这又与web service的知识有关，所以就写一个简单的例子。
看看这个接口文档，返回的数据是xml格式的，所以我们要将返回的xml格式的数据进行解析，解析我选择Android自带的pull解析。
创建一个Android工程，在src下新建一个flight.xml文件，内容如下：
[html] view plain copy print ? startCityTmp lastCityTmp新建一个Flight类，数据参考返回的数据，代码如下：
[ja] view plain copy print ? public class Flight { private String company; private String airlineCode; private String startDrome; private String arriveDrome; private String startTime; private String arriveTime; private String mode; private String airlineStop; private String week; //省略getter和setter方法 } public class Flight { private String company; private String airlineCode; private String startDrome; private String arriveDrome; private String startTime; private String arriveTime; private String mode; private String airlineStop; private String week; //省略getter和setter方法 }创建FlightsService类，实现航班时刻查询.创建FlightsService类，实现航班时刻查询.创建FlightsService类，实现航班时刻查询
[ja] view plain copy print ? public class FlightsService { /** * 获取航班時刻表 * * @param startCity * 出發城市 * @param lastCity * 到達城市 * @return * @throws Exception */ public static String getFlight(String startCity, String lastCity) throws Exception { //设置网络代理，如果你不是使用代理上网，就将这两行注释掉即可 System.setProperty("http.proxyHost", "10.123.74.137"); System.setProperty("http.proxyPort", "808"); String soap = readSoap(); soap = soap.replaceAll("startCityTmp", startCity); soap = soap.replaceAll("lastCityTmp", lastCity); byte[] entity = soap.getBytes(); String path = "http://webservice.webxml.com.cn/webservices/DomesticAirline.asmx"; HttpURLConnection conn = (HttpURLConnection) new URL(path) .openConnection(); conn.setConnectTimeout(5000); conn.setRequestMethod("POST"); conn.setDoOutput(true); conn.setRequestProperty("Content-Type", "text/xml; charset=utf-8"); conn.setRequestProperty("Content-Length", String.valueOf(entity.length)); conn.getOutputStream().write(entity); if (conn.getResponseCode() == 200) { return parseSOAP(conn.getInputStream()); } return null; } /* * string string string string */ private static String parseSOAP(InputStream xml) throws Exception { // List List flightList = null; Flight flight = null; //使用Android提供的工具类创建pullParser解析器 XmlPullParser pullParser = Xml.newPullParser(); pullParser.setInput(xml, "UTF-8"); //触发第一个事件 int event = pullParser.getEventType(); //解析xml，文档没结束就一直处理 while (event != XmlPullParser.END_DOCUMENT) { switch (event) { case XmlPullParser.START_DOCUMENT: //初始化flightlist flightList = new ArrayList(); break; case XmlPullParser.START_TAG: //遇到要处理的标签就处理 if ("AirlinesTime".equals(pullParser.getName())) { flight = new Flight(); } else if ("Company".equals(pullParser.getName())) { flight.setCompany(pullParser.nextText());

flight = null; } break; } //用next方法处理下一个事件，不然就成死循环了 event = pullParser.next(); } //在Logcat打印出来，看结果 for (int i = 0; i < flightList.size(); i++) { Log.v("AirlineCode", flightList.get(i).getAirlineCode());
