android调试命令积累--getevent

adb shell getevent -lrt

getevent 旨在获取android设备的事件信息，具体参考详细用法(本人亦初学者一枚，无法深入解释) 
sendevent 则可以向设备发送模拟事件，其中包括touch和keypress 

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,

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
