How can I read QR code once and stop QrReader

As in the examples, the QREeader reads continous. When I once read

 qreader = QREader.Builder(view.context, surface_view, QRDataListener { data ->
            printReadQrCode(data)
        }).facing(QREader.BACK_CAM)
                .enableAutofocus(true)
                .height(surface_view.height)
                .width(surface_view.width)
                .build()
    }

Here it prints continueous the read data object as long as I hold the scanner to the qr code. I would like to call printReadQrCode(data) only once it was read successfully… then stop the qreader and resume if required.

also

myTextView.post(new Runnable() {
                @Override
                public void run() {
                    myTextView.setText(data);
                }
            });

wont help, since I do not have any Views and I do not want to add artificially some View elements…

private void SetupQREader() { qrEader = new QREader.Builder(this, id_SurfaceView, new QRDataListener() { @Override public void onDetected(final String data) { Log.d(“QREader”, "Value : " + data);

            result.post(new Runnable() {
                @Override
                public void run() {
                    String msg;
                    result.setText(data);
                    qrEader.stop();
                    msg = result.getText().toString();
                    Log.e("XXXXX", msg);
                    Intent intent = new Intent(ac, QrCodeResult.class);
                    intent.putExtra("RESULT", msg);
                    startActivity(intent);
                }
            });
        }
    }).facing(QREader.BACK_CAM)
            .enableAutofocus(true)
            .height(id_SurfaceView.getHeight())
            .width(id_SurfaceView.getWidth())
            .build();
}

still getting Log two times ? why ? not understanding. and what is the use of qrEader.wait(); and how do i use and where to use?

call qReader.stop() after first scan. and use qReader.start() when need to start scanning again.
