android解析plist文件

android解析plist文件

plist，即property list，是苹果手机软件开发中经常用到的存储文件格式，其实质就是XML文件，但是它遵循一定的格式。比如包含一些指定的元素，如plist,array,string,key等。苹果提供了解析该类文件的机制，可惜在安卓开发工具中却没有提供。经常遇到的情况是，在开发苹果和安卓手机软件的时候，要统一资源文件，这个时候，我们可以采用GitHub中提供的开源android-plist-parser解决方案。

比如我们要解析一个全国省市区的一个plist文件：

 

xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> 
<plist version="1.0">

    <key>0</key> 
    <dict> 
        <key>北京市</key> 
        <dict> 
            <key>0</key> 
            <dict> 
                <key>北京市</key> 
                <array> 
                    <string>东城区</string> 
                    <string>西城区</string> 
                    <string>朝阳区</string> 
                    <string>丰台区</string> 
                    <string>石景山区</string> 
                    <string>海淀区</string> 
                    <string>门头沟区</string> 
                    <string>房山区</string> 
                    <string>通州区</string> 
                    <string>顺义区</string> 
                    <string>昌平区</string> 
                    <string>大兴区</string> 
                    <string>怀柔区</string> 
                    <string>平谷区</string> 
                    <string>密云县</string> 
                    <string>延庆县</string> 
                </array> 
            </dict>

    </dict> 
        ... 
        ... 
        ...

</plist>

那么如何在android中解析呢？

 

一：在GitHub上下载android-plist-parser

 

 

二：解压下载的包，并导入android项目的类路径里。

 

三：解析该文件，并将解析信息打印在控制台。(因为该文件不算太小，因此在新线程中运行，防止主线程卡死)
