    Assume you use the following CustomViewHolder

    public static class CustomViewHolder extends RecyclerView.ViewHolder {
        private TextView textView; 
        private TextView textView2;
        private EditText editText;
        private int position;
        public CustomViewHolder (View view) {
            super(view);
            textView = (TextView) view.findViewById(R.id.text_view);
            textView2 = (TextView) view.findViewById(R.id.text_view2);
            editText = (EditText) view.findViewById(R.id.edit_text);
            editText.addTextChangedListener(new CustomWatcher(this));
        }
    }
    

    and use the following CustomWatcher

    public static class CustomWatcher implements TextWatcher {
        private int CustomViewHolder holder;
        public CustomWatcher(CustomViewHolder holder){
            this.holder = holder;
        }
    
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }
    
        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
        }
    
        @Override
        public void afterTextChanged(Editable s) {
    
        }
    
        public int getPosition(){
            return holder.position;
        }
    }
    

    Then, in your onBindViewHolder

    @Override
    public void onBindViewHolder(final CustomViewHolder holder, final int position) {
        holder.position = position;
    }
