/**
* Returns an {@link OnTouchListener} that can be added to the anchor view
* to implement drag-to-open behavior.
* <p>
* 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.
* <p>
* Example usage:
* <pre>
* PopupMenu myPopup = new PopupMenu(context, myAnchor);
* myAnchor.setOnTouchListener(myPopup.getDragToOpenListener());
* </pre>
*
* @return a touch listener that controls drag-to-open behavior
