View.OnDragListener
android.view.View.OnDragListener |
Interface definition for a listener that's invoked when a drag event is dispatched to this
view. The listener is invoked before the view's own
View.onDragEvent(android.view.DragEvent)
method. To fall back to the view's
onDragEvent(DragEvent)
behavior, return false
from the listener method.
