The reason why it was not working, there was no date. I fixed it with the option to pick the device date (current date), the DatePickerdialog opens.

                        try {
                            String date = new SimpleDateFormat("dd-MM-yyyy").format(new Date());
                            holder.valueLabel.setText(date);
                            mItems.get(position).value = date;
