How to enable other checkboxes in recycler view if previous checkbox is checked (other checkboxes are disabled at first)?

Question

What I want to do is if April and May have a due amount then a user cannot select May if April is not selected . First, a user has to select April then the May checkbox will get enabled . If May is selected then June will get enabled .

I am not able to get position of the checkboxes so that I can do the same.

@Override
  public void onBindViewHolder(@NonNull FeeHolder holder, int position) {
      holder.textView_fee.setText(Integer.toString(list.get(position).getFeeAmount()));
      holder.textView_due.setText(Integer.toString(list.get(position).getDueAmount()));
      holder.checkBox.setText(list.get(position).getInstallmentName());

      holder.checkBox.setTag(Integer.toString(position));
      arrayList.add(holder.checkBox);
      /*if (holder.checkBox.isChecked()) {
          arrayList.add(holder.checkBox);
      }*/
      holder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
          @Override
          public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

          }
      });

Add a selected property (with getters and setters) to your list array and here's a code fragment to play with.

if (position > 0) {
  YourObject obj = list.get(position - 1);
  if(obj.dueAmount() > 0) {
    if(obj.isSelected()) {
      holder.checkBox.setEnabled(true)
    } else {
      holder.checkBox.setEnabled(false)
    }
  } else {
    holder.checkBox.setEnabled(true)
  }
}

Then, on your setOnCheckedChangeListener , update your object's selected property accordingly.

PS: This applies a chain effect if previous items have dueAmount > 0
