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

Question

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 coded 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();
      }
    }
);

This is more than likely correct, I've had the same problem in the past. – user432209 Oct 22 '10 at 16:15

I saved surface view's width and height in Surface view's overridden method OnSurfaceViewChanged(); and it worked fine for me. – Pramod May 16 '11 at 10:05
Sorry to ask (maybe stupid) questions but I can't find the OnSurfaceViewChanged Method: http://developer.android.com/reference/android/view/SurfaceView.html – Tobias Reich Oct 18 '14 at 14:04

You probably need to do something like this:
