Public methods

createDragToOpenListener

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
