Android queries: Emulated keyboard and mouse events (ADB shell implementation)

1. Send keyboard events:

Adb shell input keyevent “value”

Value and corresponding key code are listed in the following table:

Adb shell sendevent [device] [type] [code] [value]

For example, adb shell sendevent /dev/input_event0 1 229 1 press Down Press down the Menu key

Adb shell sendevent /dev/input_event0 1 229 0 press the release menu key

Note: The preceding commands must be used in combination

Complete command:

adb shell sendevent /dev/input/event4 1 139 1; adb shell sendevent /dev/input/event4 1 330 1; adb shell sendevent /dev/input/event4 0 0 0; adb shell sendevent /dev/input/event4 1 139 0; adb shell sendevent /dev/input/event4 1 330 0; adb shell sendevent /dev/input/event4 0 0 0

The number is obtained by manually clicking the Menu key according to adb shell Getevent

Other known commands are as follows:

Key Name CODE

MENU 229

HOME 102

BACK (back button) 158

CALL (call button) 231

END (end call button) 107

2. Send mouse events (Touch) :

Adb shell sendevent [device] [type] [code] [value]

sendevent /dev/input/eventX type code value

/dev/input.eventx corresponds to an event device. You can use getevent to obtain an event device

Type, code, the definition of value can see kernel/include/Linux/input. H

Case 1: Touch at a coordinate point

If you touch the screen at x 40 and y 210, the command is as follows

adb shell sendevent /dev/input/event0 3 0 40

adb shell sendevent /dev/input/event0 3 1 210

adb shell sendevent /dev/input/event0 1 330 1 //touch

adb shell sendevent /dev/input/event0 0 0 0 //it must have

adb shell sendevent /dev/input/event0 1 330 0 //untouch

adb shell sendevent /dev/input/event0 0 0 0 //it must have

Note: the above six sets of commands must be used together

Case 2: Simulated sliding tracks (downloadable and tested with aPaint software)

Here is an example of drawing a horizontal line on aPaint starting at (100,200) and ending at (108,200)

Adb shell sendevent /dev/input.event0 3 0 100 //start from point (100,200)

adb shell sendevent /dev/input/event0 3 1 200

adb shell sendevent /dev/input/event0 1 330 1 //touch

adb shell sendevent /dev/input/event0 0 0 0

Adb shell sendevent /dev/input/event0 3 0 101 step to point

adb shell sendevent /dev/input/event0 0 0 0

…………………………………… //must list each step, here just skip

Adb shell sendevent /dev/input.event0 3 0 108

adb shell sendevent /dev/input/event0 0 0 0

adb shell sendevent /dev/input/event0 1 330 0 //untouch

adb shell sendevent /dev/input/event0 0 0 0

Examples are as follows:

sendevent /dev/input/event4 3 0 258; sendevent /dev/input/event4 3 1 285; sendevent /dev/input/event4 1 330 1; sendevent /dev/input/event4 0 0 0; sendevent /dev/input/event4 1 330 0; sendevent /dev/input/event4 0 0 0

Spreadtrum platform click the coordinates (380,870) event:

adb shell “sendevent dev/input/event4 1 330 1; sendevent dev/input/event4 3 48 20; sendevent dev/input/event4 3 53 380; sendevent dev/input/event4 3 54 870; sendevent dev/input/event4 0 2 0; sendevent dev/input/event4 0 0 0; sendevent dev/input/event4 3 48 20; sendevent dev/input/event4 3 53 380; sendevent dev/input/event4 3 54 870; sendevent dev/input/event4 0 2 0; sendevent dev/input/event4 0 0 0; sendevent dev/input/event4 1 330 0; sendevent dev/input/event4 0 2 0; sendevent dev/input/event4 0 0 0”

adb shell “sendevent dev/input/event4 1 330 1; sendevent dev/input/event4 3 48 20; sendevent dev/input/event4 3 53 380; sendevent dev/input/event4 3 54 870; sendevent dev/input/event4 0 2 0; sendevent dev/input/event4 0 0 0; sendevent dev/input/event4 1 330 0; sendevent dev/input/event4 0 0 0”
