[Android] via adb shell input Escalation command simulates screen click event "Go"

Common input escalation commands:
Input text 1234 actually injected 1234 text into the interface, there is an input box, can obviously see the effect
Input KeyEvent 4 Keyboard event, 4 for return
Input TAP 100 300 click on Touchscreen event, simulate click x=100 y = 300 position
Input swipe 100 300 500 300 touchscreen slide event, analog slide, from X =100
y = 300 slide to x=500 y=300 position
Input press simulates pressing the trackball
Input roll 100 300 analog trackball slide x direction y direction 300

Get Coordinate method:
First step: Calculate scale

ADB Shell Getevent-p | Grep-e "0035"-E "0036"
Get the Event System width (0035) and high (0036)

In the case of the phone I'm currently using, the command will output the following information:
0035:value 0, Min 0, max 1602, Fuzz 0, flat 0, resolution 0
0036:value 0, Min 0, max 2503, fuzz 0, flat 0, resolution 0

0035 (w) Max 1602
0036 (h) Max 2503

Calculate the scale (with a known screen resolution, such as 1080p: 1080 (W) * 1920 (h)):
Ratew = 1080 (width of the phone screen)/1602 (max in event 0035) = 0.674
Rateh = 1920 (high on the phone screen)/2503 (max in event 0036) = 0.767

Step Two: Click on the screen to calculate the coordinates of the click position
ADB Shell GetEvent | Grep-e "0035"-E "0036"
Click on the desired location on the screen and the following output will be available:
/dev/input/event0:0003 0035 00000341
/dev/input/event0:0003 0036 000008ec

Converts the position data from 16 to 10 in the back of 0035 and 0036
width = 0x341 = 3*16*16 + 4*16 + 1 = 833
Height = 0x8ec = 8*16*16 + 14*16 + 12 = 2284
This is the position in the event system and translates it into a screen position
Screenw = Width*ratew = 833*0.674 = 561
Screenh = Height*rateh = 2284*0.767 = 1751

Finally figured it out.
The screen position coordinates just clicked (561, 1751)
