Answer 1

试试这个，

    fromDate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        final Calendar newCalendar = Calendar.getInstance();
        datePickerDialog = new DatePickerDialog(getContext(), new DatePickerDialog.OnDateSetListener() {
          public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
            newCalendar.set(year, monthOfYear, dayOfMonth);

            /*Set max date*/
            datePickerDialog.getDatePicker().getDatePicker().setMaxDate(new Date().getTime());

            // Subtract 1 month from Calendar updated date
             c.add(Calendar.MONTH, -1);

             // Set the Calendar new date as minimum date of date picker
              datePickerDialog.getDatePicker() .getDatePicker().setMinDate(newCalendar.getTimeInMillis());

          }
        }, newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
        datePickerDialog.show();
        }
});

您可以使用DatePicker的maxDate和minDate属性，并且可以使用Java Code完成相同的操作。您可以参考link获取更多信息
