android - 不要在 DatePicker 中接受过去的日期

Question

我不想在 DatePicker 中接受过去的日期。这是我的代码，我用它来显示日期选择器并在 EditText 中设置日期。

public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

        public EditText editDate;
        private Calendar dateTime = Calendar.getInstance();
        private SimpleDateFormat dateFormatter = new SimpleDateFormat("dd MMMM yyyy");

    public DatePickerFragment(EditText editText) {
        editDate = editText;
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        // Create a new instance of DatePickerDialog and return it
        return new DatePickerDialog(getActivity(), this, year, month, day);

    }

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
            dateTime.set(year, monthOfYear, dayOfMonth);
            editDate.setText(dateFormatter
                    .format(dateTime.getTime()));
        }

}

为 DatePicker 设置最小日期

public class DatePickerFragment extends DialogFragment implements
        DatePickerDialog.OnDateSetListener {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the today date as the default date in the picker
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        // Create a new instance of DatePickerDialog and return it
        DatePickerDialog dp = new DatePickerDialog(getActivity(), this, year, month, day);
        // Use the today date as the Min date in the picker 
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            dp.getDatePicker().setMinDate(c.getTimeInMillis());
        } else {
            Log.w(TAG, "API Level < 11 so not restricting date range...");
        }            
        return dp;
    }

    public void onDateSet(DatePicker view, int year, int month, int day) {
        // Do something with the date chosen by the user
    }
}
