The surface view is actually BEHIND your window, and a hole punched in the window for you to see it. You thus can put things on top of it in your window, but nothing in your window can appear behind it.

From API 5 onwards you can use setZOrderOnTop. The trick is that you have to do it in your constructor so it gets called before the view is attached to the window:

public ZenClockSurface(Context context, AttributeSet attrs) {
  super(context, attrs);

  setZOrderOnTop(true);

  SurfaceHolder holder = getHolder();
  holder.setFormat(PixelFormat.TRANSLUCENT);
}

This way you can set surface view background as Transparent. Hope this solves your problem.
