Public Methods

public static View.OnTouchListener createDragToOpenListener (Object listPopupWindow, View src)

On API KITKAT and higher, returns an View.OnTouchListener that can be added to the source view to implement drag-to-open behavior. Generally, the source view should be the same view that was passed to ListPopupWindow.setAnchorView(View).

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:

 ListPopupWindow myPopup = new ListPopupWindow(context);
 myPopup.setAnchor(myAnchor);
 OnTouchListener dragListener = myPopup.createDragToOpenListener(myAnchor);
 myAnchor.setOnTouchListener(dragListener);

Parameters

listPopupWindow	the ListPopupWindow against which to invoke the method
src	the view on which the resulting listener will be set

Returns

a touch listener that controls drag-to-open behavior, or null on unsupported APIs
