如何修复Zxing扫描仪，扫描一次后不仅扫描条形码，

Question

我要创建一个新的应用程序，有3种扫描模式，一种用于壁橱，一种用于储物柜，一种用于锁定！所有代码都在处理结果中，并且在每次扫描后我都使扫描仪恢复ScannerPreview，这是第一次扫描后，扫描仪不仅扫描条形码，而且还扫描文本的问题，如果我说一分钟或更短的时间，会扫描并显示奇怪的数字！该如何解决？

我试图看看是否只有一次扫描会发生这种情况，

这是处理结果中发生的代码

public void handleResult(Result result) {
  final String myResult = result.getText();
  final String check = myResult.trim();
    if (State == 0) {
       ClosetTextId=check;
       if (LockerAmbinDB.CheckCloset(Integer.parseInt(check)) == true) {
     try {

        ClosedId = Integer.parseInt(check);
                LockerByCloset = LockerAmbinDB.GetAllLockerByCloset(ClosedId);
                temp=String.valueOf( LockerByCloset.get(countScan).getId());


                sub_text=temp.substring(ClosetTextId.length());
                //Toast.makeText(getContext(),"" +LockerByCloset.size()+ "", Toast.LENGTH_LONG).show();
            } catch (NumberFormatException nfe) {
           {
            State++;
            Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {

                    ClosetText.setVisibility(ClosetText.GONE);
                    LockerText.setVisibility(LockerText.VISIBLE);
                    LockerNextText.setText("אנא סרוק את לוקר " + sub_text+ "");
                    LockerNextText.setVisibility(LockerNextText.VISIBLE);
                    scannerView.resumeCameraPreview(BarCodeScanner.this);

                }
            }, 1200);

        }
        else{
            functions.showAlertDialog(
                    getActivity(),
