# Interface View.OnDragListener

Enclosing class:
  `View`

Functional Interface:
  This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface public static interface View.OnDragListener
Interface definition for a callback to be invoked when a drag is being dispatched to this view. The callback will be invoked before the hosting view's own onDrag(event) method. If the listener wants to fall back to the hosting view's onDrag(event) behavior, it should return 'false' from this callback.

- ## Method Details

  - ### onDrag

    boolean onDrag(View v, DragEvent event)
    Called when a drag event is dispatched to a view. This allows listeners to get a chance to override base View behavior.
    Parameters:
      `v` - The View that received the drag event.
      `event` - The `DragEvent` object for the drag event.
    Returns:
      `true` if the drag event was handled successfully, or `false` if the drag event was not handled. Note that `false` will trigger the View to call its `onDragEvent()` handler.
