8.7 ItemDivider Subclass of RecyclerView.ItemDecoration

A RecyclerView.ItemDecoration object draws decorations—such as separators between items—on a RecyclerView. The RecyclerView.ItemDecoration subclass ItemDivider (Fig. 8.28) draws divider lines between list items. Lines 17–18 in the constructor obtain the predefined Android Drawable resource android.R.attr.listDivider, which is the standard Android list-item divider used by default in ListViews.
