I was able to figure out everything out after a few hours of
tinkering. Part of the problem was an error in the code they supply
for the OnDateSetListener callback. You need to use "@Override" before
you override any method, but for whatever reason they left it out when
they override their onDateSet method. So it should look like this:
// the callback received when the user "sets" the date in the
dialog
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;
updateDisplay();
}
};
