Display the content view in a popup window anchored to the bottom-left corner of the anchor view offset by the specified x and y coordinates. If there is not enough room on screen to show the popup in its entirety, this method tries to find a parent scroll view to scroll. If no parent scroll view can be scrolled, the bottom-left corner of the popup is pinned at the top left corner of the anchor view.

If the view later scrolls to move anchor to a different location, the popup will be moved correspondingly.

Parameters
popup PopupWindow: the PopupWindow to show
anchor PopupWindow: the view on which to pin the popup window
xoff PopupWindow: A horizontal offset from the anchor in pixels
yoff PopupWindow: A vertical offset from the anchor in pixels
gravity PopupWindow: Alignment of the popup relative to the anchor
