news 来源：原创 2025/5/10 8:26:26

驱动改完后发现上报了keycode=0

04-07 13:02:33.201 2323 2662 D WindowManager: interceptKeyTq keycode=0 interactive=false keyguardActive=true policyFlags=2000000
04-07 13:02:33.458 2323 2662 D WindowManager: interceptKeyTq keycode=0 interactive=false keyguardActive=true policyFlags=2000000

通过adb shell getevent

发现有事件上报
/dev/input/event1: 0001 00b8 00000001
/dev/input/event1: 0000 0000 00000000
/dev/input/event1: 0001 00b8 00000000
/dev/input/event1: 0000 0000 00000000

上报了b8--->16进制的184

adb shell dumusys input

4: gpio-keys
      Classes: KEYBOARD
      Path: /dev/input/event1
      Enabled: true
      Descriptor: 485d69228e24f5e46da1598745890b214130dbc4
      Location: gpio-keys/input0
      ControllerNumber: 0
      UniqueId:
      Identifier: bus=0x0019, vendor=0x0001, product=0x0001, version=0x0100, bluetoothAddress=<not set>
      KeyLayoutFile: /system/usr/keylayout/gpio-keys.kl
      KeyCharacterMapFile: /system/usr/keychars/Generic.kcm
      ConfigurationFile:
      VideoDevice: <none>
      SysfsDevicePath: /sys/devices/platform/soc/soc:gpio_keys

去device/qcom/qssi/gpio-keys.kl下面看发现没有定义

那就定义一下key 184 F14

然后把这个文件push到手机里直接验证，完美解决
