Methods Summary

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());

param
popupMenu the PopupMenu against which to invoke the method
return
a touch listener that controls drag-to-open behavior, or null on unsupported APIs

        return IMPL.getDragToOpenListener(popupMenu);
