SwipeStackAdapter 适配器的日期选择器

Question

我用谷歌搜索了很多。但我没有得到解决方案。

我的问题是我有一个片段。在片段中，我正在给一些卡片充气，即刷卡。对于那个刷卡布局，我使用 SwipeStackAdapter 来膨胀视图 xml。

在我的一个 xml 视图中，我试图实现 datepicker。

你能指导我这样做吗？我已经尝试了很多方法，但在我的情况下它不起作用

我已经解决了我的问题，

在我的适配器中

final TextView _dpResult=(TextView)convertView.findViewById(R.id.dpResult);
_dpResult.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View arg0) {
                                DialogFragment newFragment = new SelectDateFragment( );
                                newFragment.show(getFragmentManager(), "DatePicker");
                            }
                        });

选择日期片段

public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

    @RequiresApi(api = Build.VERSION_CODES.N)
    @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) {
        TextView dpResult= (TextView)getActivity().findViewById(R.id.dpResult);
        dpResult.setText(year+"-"+month+"-"+day);
    }
}

日期选择器的 xml 编码是

        <TextView
        android:id="@+id/dpResult"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:hint="yyyy-mm-dd" />

现在我可以看到我卡上的日期选择器了。谢谢
