非官方範例：

設定 datepickerdialog max/min date:

https://stackoverflow.com/questions/33051236/android-datepickerdialog-set-min-and-max-date-for-selection

Use setMaxDate().

For example, replace return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay) statement with something like this:

    DatePickerDialog dialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
    dialog.getDatePicker().setMaxDate(new Date().getTime());
    return dialog;

Calendar c = Calendar.getInstance();
c.set(2017, 0, 1);//Year,Mounth -1,Day
your_date_picker.setMaxDate(c.getTimeInMillis());
