In this case, you need to add a TextChangeListener to the first edittext field from which second edittext is taking its input.

firstEdText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            String input = charSequence.toString(); // This is the text entered in your firstEdittext

            secondEdText.setText(charSequence);
        }

        @Override
        public void afterTextChanged(Editable editable) {

        }
    });
