如何将当前日期与选择器中的日期进行比较

Question

我有一个datetimepicker，用于获取日期并在屏幕上将其设置为标签。现在我想检查输入的日期是否有效。即，输入的日期应大于或等于当前日期。请告诉我们一个代码。谢谢

StringBuffer dateStrDate = new StringBuffer();

Calendar Cal = datePickerDate.getDateTime();

Calendar Cal = datePickerDate.getDateTime();

Answer 1

DateTimePicker datePicker = DateTimePicker.createInstance(Calendar.getInstance(), "yyyy-MM-dd", null);
if(datePicker.doModal()) {
    Calendar cal = datePicker.getDateTime();
    int month=cal.get(cal.MONTH);
    int year=cal.get(cal.YEAR); 
    int date1=cal.get(cal.DATE);
}
