/*简介：字面意义是资源分析器，实际上就是获取资源并且在程序中使用，比如颜色图片等
 * 实现方法：主要利用R.java这个类，其中包括
 * R.id      组件资源引用
 * R.drawable  图片资源 （被使用）
 * R.layout  布局资源
 * R.menu   菜单资源
 * R.String  文字资源
 * R.style    主题资源 （被使用）
 * 在按顺序设置好相应的id后，就可以编写简单的getXXX函数获取需要的资源
 * 
 * 特殊的变量 ：
 * @BG_DEFAULT_COLOR 默认背景颜色（黄）
 * BG_DEFAULT_FONT_SIZE 默认文本大小（中）
