For the CameraSourcePreview to cover the whole screen you'll have to change some code in your CameraSourcePreview.java file like,

Inside your onLayout method, 

// Computes height and width for potentially doing fit width.
    int childWidth = layoutWidth;
    //int childHeight = (int)(((float) layoutWidth / (float) width) * height);
    int childHeight = layoutHeight;

Then in your barcodeCaptureActivity, find createCameraSource method, and comment out setRequestedPreviewSize like below. 

    CameraSource.Builder builder = new CameraSource.Builder(getApplicationContext(), barcodeDetector)
            .setFacing(CameraSource.CAMERA_FACING_BACK)
            //.setRequestedPreviewSize(1600, 1024)
            .setRequestedFps(15.0f);

Now you can see your CameraSourcePreview full screen.
