Question

我的对话框代码为

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;    
    }
}

来自活动：

ShowDialogScanFinger dialogscanfinger;
dialogscanfinger = new ShowDialogScanFinger();

我将其称为

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

如果我第一次打开对话框，但是如果想要第二次打开对话，那么每件事都没问题，那么我就会遇到问题......

在控制台我的应用程序崩溃和错误是
