After several tries, I got it! I’m setting the keyboard values programmatically like that

myEditText.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD); 

Or if you want you go with the XML view is like:

android: inputType = "numberPassword"

Both configs gonna display a password bullets, and as far as we are looking display numbers on the EditText we need to create a custom ClickableSpan class.

 private class NumericKeyBoardTransformationMethod extends PasswordTransformationMethod {
    @Override
    public CharSequence getTransformation(CharSequence source, View view) {
        return source;
    }
}

And finally we need implementing it to the EditText in order to display the characters typed.

myEditText.setTransformationMethod(new NumericKeyBoardTransformationMethod());

This is how my keyboard looks like now
