EditText setText() resets the keyboard

I have the next code for formatting text in TextChangedListener:

    override fun afterTextChanged(edit: Editable?) {
        editText?.removeTextChangedListener(this)
        editText?.setText(getFormattedText(edit?.toString())
        editText?.addTextChangedListener(this)
    }

So initially I get the default input type which is ABC, now when I change it to ?123 type and after entering some number the keyboard changes back to ABC.

I tried to use Editable.replace() и Editable.append() but these methods under the hood do not preserve the state of the text. And in afterTextChanged(), the text doubles. For example, I will enter "123" and call setText("12"), and the next time I enter, for example, "4", the text will come to afterTextChanged() - "1234" - "3" should not be

The question is - how to fix the keyboard reset?
