Answer 1

I have modified @MeHdi's answer. There is little fault in @MeHdi's answer which will turn into a big issue, When there is a scroll up/down in recyclerview, items position get changed and its values are getting changed or becoming empty. Also I have number of editText in a single row of recyclerview. Thanks to @MeHdi's idea. Screen looks like below

OnEditTextChanged

public interface OnEditTextChanged {
// here component_id is editTextId (findView by Id)
void onTextChanged(int component_id, int position, String charSeq);
}

Declare below in adapter class globally

private Context context;
private List dailyLiqdateList;
private OnEditTextChanged onEditTextChanged;

Adapter class

public class MyAdapter extends RecyclerView.Adapter {
private Context context;
private List dataList;

private OnEditTextChanged onEditTextChanged;

public MyAdapter(Context mContext, List dataList, OnEditTextChanged onEditTextChanged) {
    this.context = mContext;
    this.dataList = dataList;
    this.onEditTextChanged = onEditTextChanged;
}

@NonNull
@Override
public MyHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

    View myHolder = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_list,parent,false);
    return new MyHolder(myHolder);
}
@Override
public int getItemCount() {
    return dataList.size();
}

 // This is important method due to which even if you scroll list, editText values will not get changed/empty. This method will maintain its position in recyclerview
@Override
public int getItemViewType(int position) {
    return position;
}

@Override
public void onBindViewHolder(MyHolder holder, int position) {

    holder.bind(dataList.get(position), position);

    holder.firstEditText.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) {

        }

        @Override
        public void afterTextChanged(Editable editable) {
            onEditTextChanged.onTextChanged(R.id.item_firstEditText,position, holder.firstEditText.getText().toString());
        }
    });

    holder.secondEditText.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) {

        }

        @Override
        public void afterTextChanged(Editable editable) {
            onEditTextChanged.onTextChanged(R.id.item_secondEditText, position, holder.secondEditText.getText().toString());
        }
    });


}

public class MyHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    TextView headerName;
    EditText firstEditText, secondEditText;

    MyHolder(View itemView) {
        super(itemView);
        headerName = itemView.findViewById(R.id.headerNameTv);
        firstEditText = itemView.findViewById(R.id.item_firstEditText);
        secondEditText = itemView.findViewById(R.id.item_secondEditText);;

    }

    public void bind(final DataModel dto, int position) {
        if (dto != null) {
                headerName.setText(dto.getName());
        }
    }
}
}

Your Activity class in which you have recyclerview

// declare these values globally
Integer[] firstValues, secondValues;
// Declare textviews for calculating and setting total values
private TextView firstTotalTv, secondTotalTv;

// Initialize editText values array list, same as dataList size.
firstValues= new Integer[dataList.size()];
secondValues= new Integer[dataList.size()];

// setting adapter on recyclerview, write this in onCreate()
myAdapter = new MyAdapter(thisActivity, dataList, new OnEditTextChanged() {
        @Override
        public void onTextChanged(int component_id, int position, String charSeq) {
            if (component_id == R.id.item_firstEditText) {
                if (Utils.isValidStr(charSeq)) {
                    firstValues[position] = Integer.valueOf(charSeq);

                } else {
                    firstValues[position] = null;
                }
                updateTotalValue1(firstValues, firstTotalTv);
            }

            if (component_id == R.id.item_secondEditText) {
                if (Utils.isValidStr(charSeq)) {
                    secondValues[position] = Integer.valueOf(charSeq);
                } else {
                    secondValues[position] = null;
                }
                updateTotalValue1(secondValues, secondTotalTv);
            }                
        }
    });
    recyclerView.setAdapter(myAdapter);


   // Update Method, write outside of onCreate()
   private void updateTotalValue1(Integer[] editTextList, TextView totalTextView) {
    int pSum = 0, c1Sum = 0;
    for (int i = 0; i < editTextList.length; i++) {
        if (editTextList[i] != null)
            pSum += editTextList[i];
        else if (i == 0 && editTextList[i] == null)
            pSum = 0;
    }
    if (pSum > 0)
        totalTextView.setText(String.valueOf(pSum));
    else
        totalTextView.setText("");
