关于Android R文件的坑。本地图片资源id存了数据库，一开始显示正常，后来都乱序了。
项目要做一个效果，需要展示对应的数据，名字带图片，数据本地化后，图片id存入数据库，一开始显示正常，后来同事用了一段时间，突然发现图片都特么的乱了。
顿时我的心也乱了。。。 痛苦过后还得面对现实，解决方案当然是有的啦，灵光一现。在帮助类里这样写。

} 其实，我发现我们的R文件（自动生成），每次启动的资源id可能都会变化，资源id的int值并不是一成不变的，所以每次都静态统计一次，然后通过对应的key来取对应的drawable的resource id。这样动态解决了这个问题了。哈哈哈~
如果大家有什么问题，欢迎一起交流~~~
