public static View.OnTouchListener createDragToOpenListener(Object listPopupWindow, View src)
Build.VERSION_CODES.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);
listPopupWindow
- the ListPopupWindow against which to invoke the
methodsrc
- the view on which the resulting listener will be set
