Able to choose future date when setting max date in datepicker

Question

I'm targeting for and building with API level 21, using AppCompat v21.

It gives me a nicely looking new date picker, which has the unexpected property of allowing me to choose a future date when max date has been set using

datePicker.setMaxDate(Calendar.getInstance().getTimeInMillis())

The future dates are greyed out, but I can still choose any one of them. Is that a bug? Am I doing it wrong? Is there a way to prevent the user from being able to pick a future date in the date picker?

The old Holo date picker did not allow picking a future date when setting a maximum date.

UPDATE:

While it is not working properly on my Nexus 4 running stock 5.0, it is working properly on my Nexus 6 running stock Android 5.1.1. Perhaps it was a bug in Android 5.0 and it was fixed in 5.1? Can anyone confirm?

Answer 1

So to answer my own question:

I've looked at the Android source of DatePickerCalendarDelegate.java at grepcode, specifically at public void setMaxDate(long maxDate) for both Android versions 5.0 and 5.1.

What's new in 5.1 in setMaxDate() is that

mDayPickerView.goTo(getSelectedDay(), false, true, true);

has been changed to:

mDayPickerView.setMaxDate(maxDate);

It seems they fixed it there, which corresponds with my observation that it works as expected in 5.1 but not in 5.0.

And so it seems we're stuck with dealing with the fact that it doesn't work properly in Android 5.0 (days after max date are greyed out but can still be chosen).

Answer 2

I am using this and its working correctly

Call this function to open date picker

public void openDatePicker() {
        DatePickerDialog dpd = new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
        dpd.getDatePicker().setMaxDate(System.currentTimeMillis());
        dpd.show();
    }

Here is the mDateSetListener

private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
            mYear = year;
            mMonth = monthOfYear;
            mDay = dayOfMonth;
            date.setText(dayOfMonth + " / " + (monthOfYear + 1) + " / " + year); // Here date is a TextView to display date
            date.setVisibility(View.VISIBLE);
        }
    };
