方法详细资料

onItemMove

boolean onItemMove(int fromPosition,
                   int toPosition)

Called when an item has been dragged far enough to trigger a move. This is called every time an item is shifted, and not at the end of a "drop" event.

Implementations should call RecyclerView.Adapter#notifyItemMoved(int, int) after adjusting the underlying data to reflect this move.

参数:

fromPosition - The start position of the moved item.

toPosition - Then resolved position of the moved item.

返回:

True if the item was moved to the new adapter position.
