ScrollView with a SurfaceView

Currently I have a custom SurfaceView for a specific size of Panels that I used for my project. But I'm looking into expanding it hence I need a ScrollView to scroll it accordingly. But I'm not sure how do I merge the 2 together.

My SurfaceView is using a .java file to create its layout. It is not using .xml to create the layout.

//MySurfaceView.class

    public class MySurfaceView extends SurfaceView implements SurfaceHolder.Callback , Runnable{
        private SurfaceHolder surfaceHolder;
        private boolean isDestroyed = false;
        private Canvas canvas;
        private Paint paint;
        private int maxWidth;
        private int maxHeight;
        private Resources resources;
        int offset;

        final byte ON=1;
        final byte OFF=0;


        int[] ledPositionControl = new int[97];
        int ledBmpSize;
        int positionControlSize;
        int maxControl=96;
        int sizeControl=0;

        int row;
        int col;

        public MySurfaceView(Context context) {
            super(context);
            resources = context.getResources();
            init();     //load pictures 
            surfaceHolder = this.getHolder();
            surfaceHolder.addCallback(this);
            paint =new Paint();
        }

This is the class that runs the SurfaceView.

//Class that runs the SurfaceView Layout
public class drawingMode extends Activity implements OnClickListener {

    public static int screenWidth;
    public static int screenHeight;
    private SharedPreferences sPrefs;
    final byte ON = 1;
    final byte OFF = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(new MySurfaceView(this));

        DisplayMetrics metric = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(metric);
        screenWidth = metric.widthPixels; 
        screenHeight = metric.heightPixels;
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

Now how do I merge this SurfaceView into a ScrollView Layout? I have a .xml file that has a ScrollView inside but I tried to put the SurfaceView via tag wise through .xml but it didn't worked. I also tried the .addView and it didn't work too gave me some errors.

//I put this in a the onCreate of a class.
    myScrollView = new ScrollView(getApplicationContext());
            myScrollView.addView(new MySurfaceView(this));
            setContentView(R.layout.scrollsurfaceview);
