You must wait until after the first measure and layout in order to get nonzero values for getWidth() and getHeight(). You can do this with a ViewTreeObserver.OnGlobalLayouListener

public void onViewCreated(final View view, Bundle saved) {
    super.onViewCreated(view, saved);
    view.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
        public void onGlobalLayout() {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
              view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            } else {
              view.getViewTreeObserver().removeGlobalOnLayoutListener(this);
            }

            // get width and height of the view
        }
    });
}
