Hello I've created a custom adapter to my ListView in each row I have textEdit end check box I want when chceck box is clicked that text edit is strike thru and when unclicked the text view is normal.I've added a listener to checkbox but it strike thru only the last row even I click checkbox in first row the last will be change, I don't have any idea why. Here is my code

holder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    int itemPos = (int) buttonView.getTag();
                    Product element = data.get(itemPos);
                    element.setSelected(isChecked);
                    if (data.get(position).isSelected()){
                        holder.txtName.setPaintFlags(holder.txtName.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
                    }else{
                        holder.txtName.setPaintFlags(holder.txtName.getPaintFlags() & (~Paint.STRIKE_THRU_TEXT_FLAG));
                    }
                    notifyDataSetChanged();

                }
            });
            row.setTag(holder);
            holder.checkBox.setTag(position);
        }
        else
        {
            holder = (RowHolder) row.getTag();
            ((RowHolder) row.getTag()).checkBox.setTag(position);

        }
