Android系统层做键值上报广播

前言

提示：这里可以添加本文要记录的大概内容：

例如：记录Android驱动层和系统层做键值上报广播功能，kl文件是驱动和系统层的桥梁，kl文件写的内容是驱动文件设好的键值，后面的名字需要给系统层使用。

---

一、framework层如何配合驱动层做键值映射

示例：如何把上报流程从kl文件传到应用层，kl文件反应的是驱动上报的键值，后面的命名则是系统层读取的键值（如果已经有调试好广播名，也可以直接改为那个广播名，那么只要按下按键就会触发广播）下面是整理的补丁，系统定义的键值和kl文件里面的不需要一样，只需要保证名字是一样的，如KEYCODE_XX（kl中定义的宏）
