+/**
+ * A switch item which is divided into two parts: the start (left for LTR) side shows the title and
+ * summary, and when that is clicked, will expand to show a longer summary. The end (right for LTR)
+ * side is a switch which can be toggled by the user.
+ *
+ * <p>Note: It is highly recommended to use this item with recycler view rather than list view,
+ * because list view draws the touch ripple effect on top of the item, rather than letting the item
+ * handle it. Therefore you might see a double-ripple, one for the expandable area and one for the
+ * entire list item, when using this in list view.
