Clear Edit Text - adb

Question

How to clear focused Edit text using shell command.

I tried

adb shell input keyevent KEYCODE_CLEAR // Not worked 
adb shell input keyevent KEYCODE_DEL // Delete only one char
adb shell input keyevent KEYCODE_FORWARD_DEL // Not worked

With this I am only able to delete upto One character only, Is there any way I can delete/clear the focused Edit text.

Answer 1

This works for me:

function clear_input() {
    adb shell input keyevent KEYCODE_MOVE_END
    adb shell input keyevent --longpress $(printf 'KEYCODE_DEL %.0s' {1..250})
}

Then:

clear_input
