java - Android Edittext Onclick Datepickerdialog Lollipop 中出现错误

Question

我正在使用 datepickerdialog。它在 kitkat 上运行正常，但是当我在 Lollipop 上运行应用程序时，当我单击编辑文本时，它会打开一个日期选择器对话框，但当我选择日期时，它会不幸地给出停止错误。下面是 edittext 上日期选择器的代码。

private void setDateTimeField() {
                     fromLabel.setOnClickListener(this);
                     toLabel.setOnClickListener(this);



                     final DateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");  //yyyy/MM/dd HH:mm:ss
                    final Date date = new Date();
                    final String u = dateFormat.format(date);


                     Calendar newCalendar = Calendar.getInstance();
                     fromDatePickerDialog = new DatePickerDialog(this, new OnDateSetListener() {

                        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                             Calendar newDate = Calendar.getInstance();

                             newDate.set(year, monthOfYear, dayOfMonth);
                             from1 = dateFormatter.format(newDate.getTime());
                             diff1 = newDate.getTimeInMillis();
                             long d = date.getTime();


                             if((newDate.getTime()).equals(date)||(newDate.getTime()).after(date)){
                                 long d1 = (diff1 / (24 * 60 * 60 * 1000) - d / (24 * 60 * 60 * 1000)) + 1;
                                   if(d1>30){
