How can I use adb to send a longpress key event?
提问by whoabackoff
I can use something like:
我可以使用类似的东西：
adb shell input keyevent 4
and this will send a single 'Back' button press to my device. How can I send a longpress?
这将向我的设备发送一个“返回”按钮。如何发送长按？
Thanks
谢谢

You can try this command:
你可以试试这个命令：
adb shell input touchscreen swipe 170 187 170 187 2000
Your application position on screen is 170, 187; delay time is 2000 (ms);
你在屏幕上的申请位置是170、187；延迟时间为2000（ms）；
Long press HOME key:
长按HOME键：
adb shell sendevent /dev/input/event2 1 172 1
adb shell sendevent /dev/input/event2 0 0 0
timeout 1
adb shell sendevent /dev/input/event2 1 172 0
adb shell sendevent /dev/input/event2 0 0 0
You can goto cmdand type adb shell getevent | find "event2"; long press HOMEkey to see more.
您可以转到cmd并输入adb shell getevent | 找到“事件2”；长按HOME键查看更多。

When you want to delete something or repeat some Event or just input a lot of numbers, you can use code like the following. It will imitate a longpresson a keyboard:
当您想删除某些内容或重复某些事件或只是输入大量数字时，您可以使用如下代码。它将模仿键盘上的长按：
adb shell input keyevent KEYCODE_FORWARD_DEL KEYCODE_FORWARD_DEL KEYCODE_FORWARD_DEL //delete 3 times
adb shell input keyevent KEYCODE_1 KEYCODE_1 KEYCODE_1 //input value '111'
You can repeat the event or input things without limits, just like a Longpress on the key. It's the same thing. You can define your own longpass and times Now
您可以无限制地重复事件或输入内容，就像在按键上长按一样。这是同一件事。您现在可以定义自己的长传和时间

This linkdiscusses a similar problem, but the device in question (a Nexus One device)has the menu/home/back/search buttons as part of the touchscreen, not physical keys.
此链接讨论了一个类似的问题，但有问题的设备（Nexus One 设备）将菜单/主页/返回/搜索按钮作为触摸屏的一部分，而不是物理键。
This other oneappears to be more inline with injecting a physical key input, but requires accessing the *.kl file for your devices driver to determine the device, type, key-code, value-press, and value-release codes for that specific device.
另一个似乎更符合注入物理键输入，但需要访问设备驱动程序的 *.kl 文件以确定该特定的设备、类型、键代码、值按下和值释放代码设备。
However, the common link between the two appears to be
然而，两者之间的共同联系似乎是
adb shell sleep n
, where n is the length (in seconds) of the press duration.
，其中 n 是按下持续时间的长度（以秒为单位）。
Hopefully this might be of some use.
希望这可能会有一些用处。
