View.OnTouchListener getDragToOpenListener (Object popupMenu)
On API KITKAT
and higher, returns
an View.OnTouchListener
that can be added to the anchor view to
implement drag-to-open behavior.
When the listener is set on a view, touching that view and dragging outside of its bounds will open the popup window. Lifting will select the currently touched list item.
Example usage:
PopupMenu myPopup = new PopupMenu(context, myAnchor); myAnchor.setOnTouchListener(myPopup.getDragToOpenListener());
