Question

在我的应用程序中，我希望用户选择去年的日期，例如从2016年1月1日到2016年12月31日，我尝试设置mindate＆amp; maxdate ....

public static class LastYearBirthDatePicker extends DialogFragment
        implements DatePickerDialog.OnDateSetListener {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        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);

        DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, year, month, day);
        int lastYear = getCurrentYear()-1;
        Calendar min = Calendar.getInstance();
        min.set(Calendar.DAY_OF_MONTH,1);
        min.set(Calendar.MONTH,0);
        min.set(Calendar.YEAR,lastYear);
        dialog.getDatePicker().setMinDate(min.getTimeInMillis());
        Calendar max = Calendar.getInstance();
        max.set(Calendar.DAY_OF_MONTH,31);
        max.set(Calendar.MONTH,11);
        max.set(Calendar.YEAR,lastYear);
        dialog.getDatePicker().setMaxDate(max.getTimeInMillis());
        return dialog;
    }

    public void onDateSet(DatePicker view, int year, int month, int day) {


    }
}

但是有没有更好的选择来设置特定的年份我也需要特定的月份，如2016年的任何一个月（用户可以选择特定月份的任何一天）

您可以像这样设置

Calendar cal = Calendar.getInstance();
cal.set(2016, 01, 01);
cal.add(Calendar.YEAR, 1);

int xxday = cal.get(Calendar.DATE);
int xxmonth = cal.get(Calendar.MONTH);
int xxyear = cal.get(Calendar.YEAR);

datepicker.init(xxyear, xxmonth, xxday, null);

如何在datepicker中设置特定的月份或年份？
