在Fragment的布局中显示ZXING条码扫描器

Question

I have an Activity called Scanner with two fragments each using 1/2 of the display. What I am trying to achieve is running a ZXING barcode scanner in the one fragment and display the scan results in the other fragment.

I am using callback to the activity to communicate between the two fragments. Have tested that part with a button in one and a text view in the other.

The problem I am facing is that I cannot find a way (yet) to run the scanner only in the one fragment. As soon as I initiate the scanner it uses the full display for the view finder.

The scanners' first parameter is Activity and I suspect that might be where I am doing something wrong?

My Gradle:

compile 'com.google.zxing:core:3.2.1'
compile 'com.journeyapps:zxing-android-embedded:3.5.0@aar'

The code to launch the scanner:

    public void startScanner(Activity a,int cam){

    IntentIntegrator integrator = new IntentIntegrator(a);
    integrator.setDesiredBarcodeFormats(IntentIntegrator.QR_CODE_TYPES);
    integrator.setPrompt("Scan");
    integrator.setCameraId(cam);
    integrator.setBeepEnabled(true);
    integrator.setBarcodeImageEnabled(false);
    integrator.initiateScan();
}

这种使用ZXING的方式只是调用他们的应用程序来进行扫描，这不是代码的一部分。
