How do you get the width and height of a surface view

I am developing a game.I have drawn images on a surface view which is residing in a relative layout.I want that my game's look and feel should be the same in all resolutions. So now i want to measure the surfaceview/canva's width and height so that I can launch the images in proper proportion rather than hard co开发者_如何学Pythonded values. But I am unable to retrieve the height and width so please help me.

  I tried canvas.getWidth() and all but it returns 0.

Maybe it is because you try to get the width too soon.

Try this:

canvas.post(new Runnable()
    {
      public void run()
      {
        int w = canvas.getWidth();
      }
    }
);

You probably need to do something like this:
