/*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）
