Android航班时刻查询

http://www.chenwg.com/technology/android/59-flight-search.html

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：

<!--?xml version="1.0" encoding="utf-8"?--><soap:envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:body><?XML:NAMESPACE PREFIX = [default] http://WebXml.com.cn/ NS = "http://WebXml.com.cn/" /><getdomesticairlinestime xmlns="http://WebXml.com.cn/"><startcity>startCityTmp</startcity><lastcity>lastCityTmp</lastcity><thedate></thedate><userid></userid></getdomesticairlinestime></soap:body></soap:envelope>

新建一个Flight类，数据参考返回的数据，代码如下：

 

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

源码我也放上来了，下载吧！
