Public methods

createDragToOpenListener

Added in 1.1.0
Deprecated in 1.1.0
public static View.OnTouchListener createDragToOpenListener(Object listPopupWindow, View src)

On API 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);
Parameters
Object listPopupWindow

the ListPopupWindow against which to invoke the method
View src

the view on which the resulting listener will be set
Returns
View.OnTouchListener

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