        SurfaceView功能简述:
        1.Provide a dedicated drawing surface embedded inside of a view hierarchy.
        2.Provide a surface in which a secondary thread can render in to the screen.
        
        SurfaceView注意事项:
        1.All SurfaceView and SurfaceHolder.Callback methods will be called from the UI thread.       
        2.Drawing thread only touches the underlying Surface between SurfaceHolder.Callback.surfaceCreated() 
        and SurfaceHolder.Callback.surfaceDestroyed().
