I have a SurfaceView and I want the Bitmap Logo inside it in the canvas to be movable

What I'm doing wrong ?

static float x, y;
Bitmap logo;

SurfaceView ss = (SurfaceView) findViewById(R.id.svSS);   
    logo = BitmapFactory.decodeResource(getResources(), R.drawable.logo);

    x = 40;
    y = 415;
    ss.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent me) {
            try {
                Thread.sleep(50);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        switch(me.getAction()) {
        case MotionEvent.ACTION_DOWN:
            x = me.getX();
            y = me.getY();
            break;
        case MotionEvent.ACTION_UP:
            x = me.getX();
            y = me.getY();
            break;
        case MotionEvent.ACTION_MOVE:
            x = me.getX();
            y = me.getY();
            break;
            }
        return true;
        }
    });

public class OurView extends SurfaceView implements Runnable{

    Thread t = null;
    SurfaceHolder holder;
    boolean isItOK = false;


    public OurView(Context context) {
        super(context);
        holder = getHolder();

    }
    public void run (){
        while (isItOK == true){
            //canvas DRAWING
            if (!holder.getSurface().isValid()){
                continue;
            }
            Canvas c = holder.lockCanvas();
            c.drawARGB(255, 200, 100, 100);
            c.drawBitmap(logo, x,y,null);
            holder.unlockCanvasAndPost(c);
        }
    }
    public void pause(){
        isItOK = false;
        while(true){
            try {
                t.join();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            break;
        }
        t = null;
    }
    public void resume(){
        isItOK = true;
        t = new Thread(this);
        t.start();

    }
}

Now the surface view is just black .. nothing happens also its not colored 200, 100, 100
