Android如何在 fragment 中显示DatePicker？

Question

我是 Android Fragments 的新手，我想知道如何在简单的 Fragment 而不是 FragmentActivity 中显示或实现 DatePicker .

例如我的类(class)名称是:

public class FragmentAddCard extends Fragment {
}

谢谢。

在您的按钮中单击调用 DateFragment 像这样

   dob.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {

            DialogFragment newFragment = new SelectDateFragment();
            newFragment.show(getFragmentManager(), "DatePicker");

        }
    });

这是 DateFragment 的代码 fragment

  public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

        @Override
        public Dialog onCreateDialog(Bundle savedInstanceState) {
        final Calendar calendar = Calendar.getInstance();
        int yy = calendar.get(Calendar.YEAR);
        int mm = calendar.get(Calendar.MONTH);
        int dd = calendar.get(Calendar.DAY_OF_MONTH);
        return new DatePickerDialog(getActivity(), this, yy, mm, dd);
        }

        public void onDateSet(DatePicker view, int yy, int mm, int dd) {
            populateSetDate(yy, mm+1, dd);
        }
        public void populateSetDate(int year, int month, int day) {
            dob.setText(month+"/"+day+"/"+year);
            }

    }
