如果您想禁用通过日期，然后使用下面的代码日期选择器视图..
datePicker.setMinDate(System.currentTimeMillis() - 1000);并使用DatePickerDialog，然后使用下面的代码...
datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);并且你用下面两种方法使过去的时间和日期不能显示...
/**
* to display date picker dialog
*/
private void showDatePicker() {
if (mEventDatePickerDialog == null) {
if (newCalendar == null) {
newCalendar = Calendar.getInstance();
}
mEventDatePickerDialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
newCalendar.set(Calendar.YEAR, year);
newCalendar.set(Calendar.MONTH, monthOfYear);
newCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
// newCalendar.setTimeInMillis(System.currentTimeMillis());
showTimePicker();
//mTvEventDate.setText(dateFormatter.format(newDate.getTime()));
}
}, newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
mEventDatePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
mEventDatePickerDialog.show();
} else if (mEventDatePickerDialog != null && !mEventDatePickerDialog.isShowing()) {
if (newCalendar == null) {
newCalendar = Calendar.getInstance();
}
mEventDatePickerDialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
newCalendar.set(Calendar.YEAR, year);
newCalendar.set(Calendar.MONTH, monthOfYear);
newCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
// newCalendar.setTimeInMillis(System.currentTimeMillis());
showTimePicker();
//mTvEventDate.setText(dateFormatter.format(newDate.getTime()));
}
}, newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
mEventDatePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
mEventDatePickerDialog.show();
}
}
/**

private void showTimePicker() {

newDate.set(Calendar.SECOND, 00);
newCalendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
newCalendar.set(Calendar.MINUTE, minute);
newCalendar.set(Calendar.SECOND, 00);
mTvEventDate.setTextColor(ContextCompat.getColor(getActivity(), R.color.black));
mTvEventDate.setText(dateFormatter.format(newDate.getTime()));
} else {

如果您使用的是Android DatePicker，那么您可以将最小日期设置为今天的日期，因此不会启用今天之前的日期。您可以使用以下代码片段：
datePicker.setMinDate(new Date().getTime());否则，如果您使用的是DatePickerDialog：
datePickerDialog.getDatePicker().setMinDate(new Date().getTime());页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
