Android 如何从活动多次打开DialogFragment？

我的对话框代码是

public class ShowDialogScanFinger  extends DialogFragment{

    TextView t1;
    ProgressBar p1;

    @SuppressLint("NewApi")
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)         
    {
        @SuppressWarnings("unused")
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        View view = inflater.inflate(R.layout.scanyourfinger, container, false);
        getDialog().requestWindowFeature(STYLE_NO_TITLE);

        t1 = (TextView) view.findViewById(R.id.textViewScanFingerMessage);
        p1 = (ProgressBar) view.findViewById(R.id.progressBarScanFinger);
        p1.setVisibility(View.VISIBLE);

        return view;    
    }
}

从活动中：

ShowDialogScanFinger dialogscanfinger;
dialogscanfinger = new ShowDialogScanFinger();

我称之为

dialogscanfinger.show(getFragmentManager(), "scan");

如果我第一次打开对话框，一切都很好，但是如果我想第二次打开它，那么我会遇到问题

在控制台中，我的应用程序崩溃，错误为

此错误不在对话框中，您正在使用任何数组列表。？您试图在

onCreateView

代码中实现什么？这对我来说没什么意义。无论如何，我建议您重写

onCreateDialog

，而不是

onCreateView

；从我的代码中，我没有收到任何问题。你能粘贴代码吗？@DivyangMetalia我已经粘贴了
