How to use Text Watcher for multiple edit text in android?

Question

I have a situation where there will be two EditText controls, one for entering Rate Before Tax value and another one for entering Rate After Tax. I will be changing both Rate BT and Rate AT values. When I change Rate BT, then Rate AT text should change depending on Rate BT and vice versa.

Please help

It is possible to do it by setting two textwatchers for each edittexts; like... for Text2 : onTextChanged() { //change text 1 } For text1: onTextChanged() { //change text2 } — Papps, Aug 08 '18 at 07:01

You can simply do it as by adding TextWatcher to your edittext as,

rateAtEditText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
             // you can do it here, what you want to do when RateAt text change
        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    });

rateBtEditText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // you can do it here, what you want to do when RateBt text change
        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    });
