Question

我正在开发一个我需要日期选择器对话框的android项目。我已经完成了以下代码。

private void setDateTimeField() {

    Calendar newCalendar = Calendar.getInstance();

    firstMemberDatePickerDialog = new DatePickerDialog(getActivity(), new OnDateSetListener() {

        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
            Calendar newDate = Calendar.getInstance();
            newDate.set(year, monthOfYear, dayOfMonth);
            BootstrapEditTextDob.setText(dateFormatter.format(newDate.getTime()));
        }

    },newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));

}

现在，当用户打开日期选择器对话框时，它应该是18年前的过去日期。如何实现这个目标？

要设置为过去日期，请使用以下代码

  int no_of_years_past=18;

   Calendar calendar = Calendar.getInstance();
                    int year = calendar.get(Calendar.YEAR);
                    int month = calendar.get(Calendar.MONTH);
                    int day = calendar.get(Calendar.DAY_OF_MONTH);

    firstMemberDatePickerDialog = new DatePickerDialog(getActivity(), new OnDateSetListener() {

    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        Calendar newDate = Calendar.getInstance();
        newDate.set(year, monthOfYear, dayOfMonth);
        BootstrapEditTextDob.setText(dateFormatter.format(newDate.getTime()));
    }

    },year-no_of_years_past, month, day);

您可以使用相同的方法设置月份或日期
