android - 如何获取android的触摸码事件

Question

有人可以帮助我了解如何获取我可以通过 adb 发送的触摸码事件以在我的 Android 手机（iCS）中启动应用程序。当我尝试getevent()时，它给我带来了很多事件。我如何知道我选择了哪个触摸事件？

getevent 允许您按设备以及其他内容进行过滤：

Usage: getevent [-t] [-n] [-s switchmask] [-S] [-v [mask]] [-d] [-p] [-i] [-l] [-q] [-c count] [-r] [device]
    -t: show time stamps
    -n: don't print newlines
    -s: print switch states for given bits
    -S: print all switch states
    -v: verbosity mask (errs=1, dev=2, name=4, info=8, vers=16, pos. events=32, props=64)
    -d: show HID descriptor, if available
    -p: show possible events (errs, dev, name, pos. events)
    -i: show all device info and possible events
    -l: label event types and names in plain text
    -q: quiet (clear verbosity mask)
    -c: print given number of events then exit
    -r: print rate events are received

因此，请使用您的触摸设备过滤事件，例如

getevent /dev/input/event0
