模拟来自ADB终端的按键组合 [英] Simulating combination of key presses from ADB terminal
问题描述
我想向Android版Chrome发送" CTRL + W "以关闭活动标签.我尝试了很多事情，但是从终端上实现它并没有成功. (如果我将USB键盘与OTG连接，则可以使用CTRL + W关闭选项卡)
I want to send "CTRL + W" to the Chrome for Android to close active tab. I tried lots of things but there is no success to achieve it from terminal. (If i connect a USB Keyboard with OTG, i can close the tab with CTRL+W)
首先，我不想为此编写应用程序，我只希望Shell命令从Tasker中使用它.
Firstly i do not want to write a application for this, i only want a shell command to use it from Tasker.
我在某处读到要实现此功能(CTRL + W按键)，我必须像这样模拟按键:
I read somewhere that to achieve this (CTRL+W keypress), i have to simulate key presses like this:
向下CTRL
下W
上W
向上CTRL
Down CTRL
Down W
Up W
Up CTRL
要在终端上实现这一点，似乎我必须使用" sendevent ".
And to achieve this from terminal, it seems i have to use "sendevent".
我可以用"sendevent"模拟所有硬件按键，但是不能用它模拟普通按键.
I can simulate all hardware keypress with "sendevent" but can not simulate the normal keys with it.
例如，上下按电源键:
sendevent /dev/input/event1 1 116 1
sendevent /dev/input/event1 0 0 0
sendevent /dev/input/event1 1 116 0
sendevent /dev/input/event1 0 0 0
我使用此命令，但是我不能使用此命令发送普通密钥. (例如a，b，c等)
i use this commands, but i can not use this commands to send normal keys. (for example a,b,c etc)
event1是gpio键，所以我正在使用它.其他所有输入事件都是传感器，一个是充电驱动器. (max77693-muic)
The event1 is the gpio-keys, so i'm using it. And all the other input events are sensors and one is the charging driver. (max77693-muic)
"getevent -p"的输出表明:
The output of the "getevent -p" says that:

我的gpio-keys布局文件"/system/usr/keylayout/gpio-keys.kl"也是如此:
Also my gpio-keys layout file "/system/usr/keylayout/gpio-keys.kl" like this:
key 115 VOLUME_UP WAKE
key 114 VOLUME_DOWN WAKE
key 116 POWER WAKE
key 172 HOME WAKE
我可以使用以下命令发送所有正常的按键事件:
I can send all normal keyevents with:
"input keyevent KEYCODE_X"
并发送多个:
"input keyevent KEYCODE_X KEYCODE_Y"
您应该认为它可以像这样工作:
You should think it can works like this:
"input keyevent KEYCODE_CTRL_LEFT KEYCODE W"
但是按键事件立即上下移动，我不能用它发送CTRL + W组合键.
but keyevent down and up immediatly and i can not use it to send CTRL+W combination.
我知道，答案应该是"sendevent".但是我找不到.
I know, the answer should be with "sendevent". But i can not find.
我还试图将一些伪造的密钥添加到密钥布局文件中，如下所示:
I also tried to adding some fake keys into the key layout file like this:
key 115 VOLUME_UP WAKE
key 114 VOLUME_DOWN WAKE
key 116 POWER WAKE
key 172 HOME WAKE
key 19 Q
我重新启动电话，然后尝试:
i restarted the phone, then tried:
sendevent /dev/input/event1 1 19 1
sendevent /dev/input/event1 0 0 0
sendevent /dev/input/event1 1 19 0
sendevent /dev/input/event1 0 0 0
但是它永远不会在任何文本框中写入"Q".
But it never writes "Q" into the any textbox.
请帮助，谢谢您的帮助.
Please help, thanks for your helps.
推荐答案
哦，是的！我不知道为什么，但是每当我感到被卡住时，我都会进入stackoverflow，一旦我开始写问题就以某种方式找到答案... xD 无论如何，我可以通过以下过程来做到这一点:
Oh YES!! I dont know why but whenever I feel stuck I come to stackoverflow and as soon as I start writing the question somehow I find the answer... xD Anyways, I was able to do it by following procedure:
- 转到/system/usr/keylayout/
- 在我的情况下，没有gpio键，反正打开 Generic.kl
- 它具有模拟任何东西所需的所有键码...例如CTRL_RIGHT键码为97，W键码为17
- 这就是您所需要的，现在打开tasker->新任务->添加等待5秒->运行shell:
input keyevent 97 input keyevent 17
- Go to /system/usr/keylayout/
- In my case there was no gpio-keys, anyways open Generic.kl
- It has all the keycodes you would need to simulate anything... such as for CTRL_RIGHT keycode is 97 and for W keycode is 17
- Thats all you need, now open tasker --> New task --> Add wait 5 sec --> Run shell:
input keyevent 97 input keyevent 17
现在运行命令并快速打开chrome，瞧！ 5秒钟后，您的标签页就会消失！
Now run the command and quickly open chrome, voila! in 5 secs you will see your tab disappearing!
希望对以后的任务专家都有帮助；)
Hope that helps all the future tasker pros ;)
荣誉...
