@Override

public void onDateChanged(DatePicker view, int year,

int monthOfYear, int dayOfMonth) {

if (isDateAfter(view)) {

Calendar mCalendar = Calendar.getInstance();

view.init(mCalendar.get(Calendar.YEAR),

mCalendar.get(Calendar.MONTH),

mCalendar.get(Calendar.DAY_OF_MONTH), this);

}

Calendar tempCalendar = Calendar.getInstance();

tempCalendar.set(tempView.getYear(), tempView.getMonth(),

tempView.getDayOfMonth(), 0, 0, 0);
