Hi all,
Suppose I draw somthing on a canvas and I need to put it to the center of
it. Is there any way of setting a canvas so everything i draw would
automatically be aligned to the center ???

Thanks in advance

That would be a nix. Sorry, but you'll have to center everything manually. It's not terribly hard ('width' and 'height' are the width and height respectively of your content):

Point origin = new Point();

origin.x = (canvas.getSize().x - width) / 2;
origin.y = (canvas.getSize().y - height) / 2;

Code should use client area and not size:

Point origin = new Point();

origin.x = (canvas.getClientArea().width - width) / 2;
origin.y = (canvas.getClientArea().height - height) / 2;
