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();
            }
            view.setMaxDate(timeInMilliseconds);
            datePicker.setText(dayOfMonth + "/" + monthOfYear + "/" + year);
        }
    };

    dpDialog.show();

Answer 1

您可以为日期选择器设置 MaxDate 和 MinDate 限制

setMinDate(long minDate)

setMaxDate(long maxDate)

通过此获取您的当前日期：

Calendar calendar=Calendar.getInstance();
    int mDay = calendar.get(Calendar.DAY_OF_MONTH), mMonth = calendar.get(Calendar.MONTH), mYear = calendar.get(Calendar.YEAR);

并检查是否有 select 数据，即 myMonth < mMonth+3 与否。

Answer 2

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();

我为我的一个项目做了同样的事情。我相信你和我一样在这里使用图书馆。这是我实现它的方法：

Calendar currentdate= Calendar.getInstance();
            Calendar lastdate = Calendar.getInstance();
            lastdate.set(currentdate.get(Calendar.YEAR), currentdate.get(Calendar.MONTH), currentdate.get(Calendar.DAY_OF_MONTH) + 90);
            DatePickerDialog datePickerDialog = DatePickerDialog.newInstance(HomeActivity.this, currentdate.get(Calendar.YEAR), currentdate.get(Calendar.MONTH), currentdate.get(Calendar.DAY_OF_MONTH));
            datePickerDialog.setMinDate(currentdate);
            datePickerDialog.setMaxDate(lastdate);
            datePickerDialog.show(getFragmentManager(), "yourtag");
