In order to argue the difference(s) of getAdapterPosition(), getLayoutPosition(), and also position; we would notice the cases below:

1.position argument in onBindViewHolder() method:

We can use the position to bind data to the view and it is okay to use position argument to do this, but it is not okay to use position argument to handle user clicks and if you used it you will see a warning tells you "not to treat position as fixed and use holder.getAdapterPosition() instead".

2.getAdapterPosition():

This method always consists the updated adapter’s position of the holder. It means whenever you clicked on an item, you ask the adapter about it’s position. so you will get the latest position of this item in terms of Adapter’s logic.

3.getLayoutPosition():

Sometimes, it is needed to find the position in terms of the updated layout (the last passed layout that the user is seeing now), for example: If the user asks for the third position he can see and you use swipe/dismiss for items or apply any animation or decorations for items it will be better to use getLayoutPosition() instead of getAdapterPosition(), cause you will always be sure that you are dealing with the items’ position in terms of the latest passed layout.
