4,782 Pointswhat is View Group Root?
Hi I would just like to know what is a View Group Root. Ben stated that in creating our inflater
convertView = LayoutInflater.from(mContext).inflate(R.layout.daily_list_item, null);
the view group root is set to null and Ben said it is not needed. However, may I ask what is it?

Treehouse TeacherThe second parameter is an optional view to be the parent of the generated hierarchy. http://developer.android.com/reference/android/view/LayoutInflater.html#inflate(int, android.view.ViewGroup)
So if we specified a ViewGroup for the second parameter, R.layout.daily_list_item would be added as a child to the ViewGroup that we specified. If we leave the second parameter as null, R.layout.daily_list_item would be added as a child to the root ViewGroup which is the top element in the layout.
In this image, the RelativeLayout at top is the root ViewGroup.
