SmartPhone手机上查看QQ天气预报

4/26/2005来源:移动短信技术人气:39909

  智能手机应用程序开发是软件开发的一个新的热点,但如何才能跨入这道门楣呢?今天我通过为自己的多普达565手机添加一个天气预报程序来向大家讲解一下。我们都知道QQ有一个免费提供给Blog引用的天气预报服务网址http://appnews.qq.com/cgi-bin/news_qq_search?city=上海(上海是我自己所在城市,如果想看自己的城市,在浏览器中改成城市名称即可),现在我使用QQ提供的这个服务,将其包装部署为一个Web服务,并编写程序使得我的多普达565智能手机能使用这个Web服务。

  设备要求:

  PC开发环境:Windows xp SP2,Visual Studio 2003.NET,.NET Framework 1.1 SP1

  操作系统:Windows Mobile(TM) 2003第二版,版本4.21.1088(Build 14235.2.0.0)

  智能手机:多普达565

  一、环境安装

  首先我们必须安装.NET Mobile所需要的开发环境,必须安装的软件(如下软件都是微软提供免费下载和使用的)

  1、Microsoft ActiveSync 3.7.1

  下载网址:http://www.microsoft.com/windowsmobile/downloads/activesync37.mspx,里面有中文版本,或者,在手机附带的微软光盘里面有安装程序;最新版本Microsoft ActiveSync 3.8出来了,可以到摘要的页面中去找链接下载,但这个程序我还是用的老版本。

  作用:同步手机和PC机数据的程序

  2、Microsoft SMARTPHONE 2003 SDK.msi

  下载网址:

  http://download.microsoft.com/download/e/3/1/e310bb99-2f33-4d79-bb8a-41d9cb3c79b4/Microsoft SMARTPHONE 2003 SDK.msi

  3、MobileAppDevToolkit2004.exe

  下载地址:http://download.microsoft.com/download/b/2/5/b25742c0-daa3-4a8c-988d-a947a35e0a68/MobileAppDevToolkit2004.exe

  二、设计并部署WebService

  1、建立一个名为WeatherService的WebService,并将QQ的天气服务转为xml WebService服务,部署在一台具有固定ip的服务器上。

  2、新建一个WeatherDataSet.XSD,存储我们的天气信息

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema id="WeatherDataSet" targetNamespace="Ezhi.Services.WeatherService" elementFormDefault="qualified"
  attributeFormDefault="qualified" xmlns="Ezhi.Services.WeatherService"    xmlns:mstns="Ezhi.Services.WeatherService"
  xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">

<xs:element name="WeatherDataSet" msdata:IsDataSet="true">
<xs:complexType>
 <xs:choice maxOccurs="unbounded">
  <xs:element name="WeatherDS">
   <xs:complexType>
    <xs:sequence>
     <xs:element name="CityName" type="xs:string" minOccurs="0" />
     <xs:element name="Date1" type="xs:string" minOccurs="0" />
     <xs:element name="Weather1" type="xs:string" minOccurs="0" />
     <xs:element name="Temp1" type="xs:string" minOccurs="0" />
     <xs:element name="WindPower1" type="xs:string" minOccurs="0" />
     <xs:element name="Date2" type="xs:string" minOccurs="0" />
     <xs:element name="Weather2" type="xs:string" minOccurs="0" />
     <xs:element name="Temp2" type="xs:string" minOccurs="0" />
     <xs:element name="WindPower2" type="xs:string" minOccurs="0" />
    </xs:sequence>
   </xs:complexType>
  </xs:element>
 </xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>

  3、WeatherService的源代码如下

  记得将在Web.Config文件加入以下节点,使得WebService能被外部访问

<!-- WebService 获取的途径 -->

<add name="HttpSoap"/>
<add name="HttpPost"/>
<add name="HttpGet"/>
<add name="HttpPostLocalhost"/?
<add name="Documentation"/>

  三、新建手机应用程序项目

  1、新建一个智能设备应用程序,在主面板上拖放如图2所示的几个控件,其中timer是用来检查是否数据已经下载完毕的。

  四、在多普达565手机上部署并运行

  1、在VS.NET2003的“解决方案WeatherService”上点击右键,选择”部署解决方案”,出现一下对话框


图4-部署解决方案

  选择“部署”,“部署”完成后,手机上将显示如下界面


图5、手机界面之一-部署

  因为我的PC机器上安装了.NET Framework1.1SP1,所以会提示这个界面,选择“确定”,继续执行安装部署:


图6、手机界面之二-选择安装位置

  选择安装位置为”Sotrage Card”,选择“完成”,这个时候程序就部署完毕了,

  使用Resco Explore 2003,找到安装部署后程序所在的目录,在 \Sorage\Program Files\WeatherService\ 目录下面,执行程序WeatherService.exe,将出现如下画面:


图7、手机界面之三-开始执行程序 选择“是”。

  之所以出现这个画面,是因为程序没有经过系统的认证,也是微软安全方面的一个体现,即时这个程序会正常执行,也不会冒然打出电话!

  程序执行之后,会出现如下画面,选择需要查询的城市名称,点“确定”


图8、手机界面之四-程序界面

  之后程序标题会变为“正在下载…”,程序通过GPRS上网读取部署在Internet上的WebService


图9、手机界面之五-运行界面

  稍等几秒钟之后,便会看到所需要的天气信息数据
