Button - bring to front

I have a button which is part of surfaceView(1). I have created another view(cro开发者_JAVA技巧pView extends surfaceView(2)) on top of this surfaceView. This view has the height and width to match the parent.

But I want the buttons that are part of (1) to be visible in (2). How do I get this? I used button.bringToFront() But this did not seem to help!

Any help is appreciated. Thanks
