java - 如果 DatePickerDialog 被取消，如何禁用 TimePickerDialog？

Question

我目前正在制作一个待办事项列表应用程序。我有一个提醒功能，如果用户单击它，则会显示日期选择器对话框和时间选择器对话框。

但是，如果用户在日期选择器对话框上按“取消”，那么我不想显示时间选择器对话框。任何帮助将不胜感激。

这是按下“提醒”按钮时我的代码。

 //When Reminder button clicked, show datepickerdialog and timepickerdialog
    public void openCalendar(View view) {

            final Calendar notifycalendar = Calendar.getInstance();
            notifyyear = notifycalendar.get(Calendar.YEAR);
            notifymonth = notifycalendar.get(Calendar.MONTH);
            notifydayOfMonth = notifycalendar.get(Calendar.DAY_OF_MONTH);


        final DatePickerDialog notifydatePickerDialog = new DatePickerDialog(Editor_Activity.this,
                new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker datePicker, int notifyyear, int notifymonth, int notifydayOfMonth) {

                        String notifyDate;

                        notifyDate = notifydayOfMonth + "/" + (notifymonth + 1) + "/" + (notifyyear);
                        notifyDateStringfromCalendar = notifyDate;

                    }

                }, notifyyear, notifymonth, notifydayOfMonth);

现在在日期选择器对话框的 setOnCancelListener 中，我想要一些代码来隐藏时间选择器对话框。

        notifydatePickerDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
            @Override
            public void onCancel(DialogInterface dialog) {
                String notifyDate;

                notifyDate = notifydayOfMonth + "/" + (notifymonth + 1) + "/" + (notifyyear);
                notifyDateStringfromCalendar = notifyDate;

            }
        });

        TimePickerDialog notifytimePickerDialog = new TimePickerDialog(Editor_Activity.this,
                new TimePickerDialog.OnTimeSetListener() {
                    @Override
                    public void onTimeSet(TimePicker timePicker, int notifyhourOfDay, int notifyminute) {

                        String notifyTime;

                        notifyTime = notifyhourOfDay + "/" + notifyminute;
                        notifyTimeStringfromCalendar = notifyTime;    

                    }
                }, notifyhourOfDay, notifyminute, false);


        notifytimePickerDialog.show();


        //DatePicker Dialog shows with not title as well as minimum date set
        notifydatePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis());
        notifydatePickerDialog.setTitle("");
        notifydatePickerDialog.show();
    }

Answer 1

其实，找到答案非常简单。

我只需将“notifydatePickerDialog.setOnCancelListener”移动到 TimePicker 对话框下方并添加“notifytimePickerDialog.hide();”到函数。

显然，日期选择器对话框的取消按钮无法读取其上方的时间选择器对话框。
