Android 单击中性按钮时在DatePickerDialog中获取日期设置

当按下空档按钮时，我试图让我的

DatePickerDialog

打开一个

TimePickerDialog

，但是，似乎我在试图找到答案时遇到了死胡同

• 首先，我想输入一个

  OnClick

  listener，但是我该如何获得日期呢
• 其次，如果我在

  datePickerDialog

  中使用

  onDateSet

  ，如何检查是否按下了空档按钮

任何帮助都将不胜感激

public class DatePickerDialogFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{
int position;

@SuppressLint("ValidFragment")
public DatePickerDialogFragment(int position) {
    this.position = position;
}
public DatePickerDialogFragment() {
    this(-1);
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    final Calendar calendar = Calendar.getInstance();
    int year = calendar.get(Calendar.YEAR);
    int month = calendar.get(Calendar.MONTH);
    int day = calendar.get(Calendar.DAY_OF_MONTH);

    DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(), this, year, month, day);
    datePickerDialog.setCanceledOnTouchOutside(false);
    datePickerDialog.setButton(DialogInterface.BUTTON_NEUTRAL, "Set Time", //What do I do here?);
    return new DatePickerDialog(getActivity(), this, year, month, day);
}

@Override
public void onCancel(DialogInterface dialog) {
    if (position != -1)
    new RecyclerAdapter(getActivity()).notifyItemChanged(position);
}

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    Log.d("We have liftoff!", "DPD Listener called!");
    Log.d("onDateSet method", "Date set for: "+ dayOfMonth + "/" + monthOfYear + "/" + year);

    if (position == -1) {
        ((MainActivity) getActivity()).setAlarm(year, monthOfYear, dayOfMonth);
        // Call method from other activity
    }
    else {
        ((MainActivity)getActivity()).setAlarm(position, year, monthOfYear, dayOfMonth);
    }
}
}

好吧，我以前应该想到这一点，但我所做的只是使用

datePickerDialog.getDatePicker.getWhatever

从DatePicker获取我的值，然后传递它。我真的是个白痴。
