adb shell sendevent调试input事件

1，adb shell sendevent使用说明

C:\Users\luoqingyan>adb shell sendevent --help
usage: sendevent DEVICE TYPE CODE VALUE

Sends a Linux input event.

2，adb shell sendevent调试技巧

KEY_VOLUMEUP的down和up事件：
$ getevent
/dev/input/event2: 0001 0073 00000000  // 十六进制
/dev/input/event2: 0000 0000 00000000
/dev/input/event2: 0001 0073 00000001
/dev/input/event2: 0000 0000 00000000
即：
$ getevent -l
/dev/input/event2: EV_KEY       KEY_VOLUMEUP         UP
/dev/input/event2: EV_SYN       SYN_REPORT           00000000
/dev/input/event2: EV_KEY       KEY_VOLUMEUP         DOWN
/dev/input/event2: EV_SYN       SYN_REPORT           00000000

KEY_VOLUMEUP调试命令：
adb shell sendevent /dev/input/event2 1 115 0  // 十进制  DOWN 事件
adb shell sendevent /dev/input/event2 0 0 0    // SYNC 上报 DOWN 事件

adb shell sendevent /dev/input/event2 1 115 1  // UP 事件
adb shell sendevent /dev/input/event2 0 0 0    // SYNC 上报 UP 事件

KEY_VOLUMEDOWN的down和up事件：
$ getevent
/dev/input/event2: 0001 0072 00000001
/dev/input/event2: 0000 0000 00000000
/dev/input/event2: 0001 0072 00000000
/dev/input/event2: 0000 0000 00000000
即：
$ getevent -l
/dev/input/event2: EV_KEY       KEY_VOLUMEDOWN       DOWN
/dev/input/event2: EV_SYN       SYN_REPORT           00000000
/dev/input/event2: EV_KEY       KEY_VOLUMEDOWN       UP
/dev/input/event2: EV_SYN       SYN_REPORT           00000000

KEY_VOLUMEDOWN调试命令：
adb shell sendevent /dev/input/event2 1 114 0  // 十进制  DOWN 事件
adb shell sendevent /dev/input/event2 0 0 0    // SYNC 上报 DOWN 事件

adb shell sendevent /dev/input/event2 1 114 1  // UP 事件
adb shell sendevent /dev/input/event2 0 0 0    // SYNC 上报 UP 事件

$ getevent //能得知哪个/dev/input/eventXXX发出的按键事件

3，adb shell sendevent使用实例

一定要先有Down事件，才能有Up事件
$ adb shell
$ su
// dev/input/event0 对应的是电源键Power事件event // 一定要找准event
// KEY_POWER，Power键 Down事件
# sendevent /dev/input/event0 1 116 1 && sendevent /dev/input/event0 0 0 0
// KEY_POWER，Power键 Up事件
# sendevent /dev/input/event0 1 116 0 && sendevent /dev/input/event0 0 0 0

// /dev/input/event2 对应的是音量键Volume事件event // 一定要找准event
// KEY_VOLUMEUP，音量+键 Down事件
# sendevent /dev/input/event2 1 115 1 && sendevent /dev/input/event2 0 0 0
// KEY_VOLUMEUP，音量+键 Up事件
# sendevent /dev/input/event2 1 115 0 && sendevent /dev/input/event2 0 0 0

// KEY_VOLUMEDOWN，音量-键 Down事件
# sendevent /dev/input/event2 1 114 1 && sendevent /dev/input/event2 0 0 0
// KEY_VOLUMEDOWN，音量-键 Up事件
# sendevent /dev/input/event2 1 114 0 && sendevent /dev/input/event2 0 0 0

4，adb shell sendevent模拟滑动事件也是同上的方法
