createDragToOpenListener
static funcreateDragToOpenListener(
listPopupWindow: Any!,
src: View!
): OnTouchListener!
Deprecated: Use createDragToOpenListener(ListPopupWindow, View)
that takes in ListPopupWindow
instead of Object
.
On API android.os.Build.VERSION_CODES#KITKAT
and higher, returns an 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);
