在静态类中使用非静态Spinner

Question

我正在努力做到这一点：

1. 在DatePickerDialog用户设置日期
2. 日期将以Spinner编写

问题是包含OnDateSet方法的DatePickerFragment类是静态的，而微调器是非静态的。在OnDateSet方法中我需要将项添加到适配器并调用方法Spinner.setSelection（int i）

public void onDateSet(DatePicker view, int year1, int month1, int day1) {
    firstdate = day1 + "/" + month1 + "/" + year1;
    addapter.add(firstdate);
    Spinner.setSelection(1);
}

任何人都可以帮助我吗？ 提前致谢！ 菲利普

全班：

 public static class DatePickerFragment extends DialogFragment
                            implements DatePickerDialog.OnDateSetListener {

           @Override
           public Dialog onCreateDialog(Bundle savedInstanceState) {
               // Use the current date as the default date in the picker
               final Calendar c = Calendar.getInstance();
               int year1 = c.get(Calendar.YEAR)-25;
               int month1 = 0;
               int day1 = 1;


               // Create a new instance of DatePickerDialog and return it
               return new DatePickerDialog(getActivity(), this, year1, month1, day1);
           }

           public void onDateSet(DatePicker view, int year1, int month1, int day1) {
               firstdate = day1 + "/" + month1 + "/" + year1;
           }

       }
