Ok, I figured it out. When you use LayoutInflater.inflate(id, root), the return value will be the inflated xml root if you _didn't_ provide the root, or it will be the root if you did. To remedy the problem I was having, I simple passed null for the root and then called mContainerLayout.addView (mInnerLayout) and it worked. What was happen is that it was returning the root and I thought it was the inner layout. ;)
