android - 我已经采取了日期选择器对话框。我想限制选择从当前日期到 future 3 个月的日期

Question

public void DateDialog() {
    DatePickerDialog.OnDateSetListener listener = new DatePickerDialog.OnDateSetListener() {

        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

            long timeInMilliseconds = 0;
            String givenDateString = "Tue Jun 23 16:08:28 GMT+05:30 2016";
            SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy");
            try {
                Date mDate = sdf.parse(givenDateString);
                timeInMilliseconds = mDate.getTime();
                System.out.println("Date in milli :: " + timeInMilliseconds);
            } catch (ParseException e) {
                e.printStackTrace();
            }

            datePicker.setText(dayOfMonth + "/" + monthOfYear + "/" + year);

Answer 1

Calendar calendar = Calendar.getInstance();//get the current day
    calendar.add(Calendar.MONTH,3);
    long afterThreeMonthsinMilli=calendar.getTimeInMillis();
    DatePickerDialog dpDialog = new DatePickerDialog(getActivity(), listener, mYear, mMonth, mDay);
    dpDialog.getDatePicker().setMaxDate(afterThreeMonthsinMilli);
    dpDialog.show();
