在 interceptKeyBeforeDispatching 方法的亮度键的触发处：

if (keyCode == KeyEvent.KEYCODE_BRIGHTNESS_UP || keyCode == KeyEvent.KEYCODE_BRIGHTNESS_DOWN) 
               int direction = keyCode == KeyEvent.KEYCODE_BRIGHTNESS_UP ? 1 : -1;
                //wangrui 14-inch machine, set the brightness key transposition
                if ("3".equals(SystemProperties.get("xxx.scakeypad")))
                    direction = direction*-1;
