Android Q 按键添加流程详解

•                   debounce-interval = <2>;/* 按键去抖时间，单位ms，如果出现按键不稳定，请适当加大 */
  

•                   wakeup-source;
  

•           };
  

  };

2\. 修改pinmap-sp\*\*3a.c文件

-------------------------



修改方法如下：

二、Framework 层添加按键响应方法

=====================



通过`getevent`查看驱动调节的按键值是否上传ok。



命令查看方法如下：
