3.1. Using a custom layout with the scanning activity

In order to use a custom layout with the provided ScannerCompatActivity, two fields need to be changed to point it. You can change these attributes in your activity’s onCreate() lifecycle step.

import com.enioka.scanner.activities.ScannerCompatActivity;

public class MyScanningActivity extends ScannerCompatActivity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate();
        layoutIdLaser = R.layout.activity_parcel_scan_laser;
        layoutIdCamera = R.layout.activity_parcel_scan_camera;
    }
}

Here, layoutIdLaser is the layout used when handling laser scanner devices, and layoutIdCamera is the layout used when using the device’s camera as a scanner.

To ensure activity is able to properly switch to the camera when needed, you should include the following view block in the <layout>.xml file used by layoutIdCamera:

<com.enioka.scanner.camera.CameraBarcodeScanView
    android:id="@+id/camera_scan_view"
    app:forceCameraApiVersion="Auto"
    app:maxDistortionRatio="0.3"
    app:maxResolutionY="1080"
    app:previewRatioMode="fillAvailableSpace"
    app:readerMode="Auto"
    app:storePreferredResolution="false"
    app:targetColor="@color/colorRed"
    app:targetIsFixed="false"
    app:targetStrokeWidth="5"
    app:useAdaptiveResolution="true"  />

Should you choose a different ID for this view, remember to also change the value of cameraViewId in the activity.
