You should just be using mLayout.getViewTreeObserver() in onGlobalLayout(), rather than trying to access the old one. Eg.

mLayout.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
    public void onGlobalLayout() {
        scrollToGridPos(getCenterPoint(), false);
        mLayout.getViewTreeObserver().removeOnGlobalLayoutListener(this);        
    }
});
