you can do it programmatically as follows:

mToolbar.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            ImageView imageView = (ImageView)mToolbar.findViewById(R.id.logo);
            if( mToolbar == null ){
                return;
            }
            int toolbarWidth = mToolbar.getWidth();
            int imageWidth = imageView.getWidth();
            imageView.setX((toolbarWidth-imageWidth)/2);
        }
    });

customise your layout_toolbar.xml:
