如何在RecyclerView中执行从顶部到某个位置的滚动项目？

Question

I have recyclerview, that have LinearLayoutManager and in it reverseLayout=true . How can I scroll item with some position to the top of the screen? Regular recyclerView.scrollToPosition or layoutManager.scrollToPosition didn't work, because item scrolled by that way displayed at the bottom of list and under the screen.

Answer 1

用这个 ：-

linearLayoutManager!!.scrollToPositionWithOffset(0, 0)

Answer 2

try this

recyclerView.scrollToPosition(recyclerView.getChildCount());

or

recyclerView.scrollToPosition(list.size());

Edit

in your adapter you can check your current position, if you reach desired position you can scroll recyclerView to particulate position using interface

Answer 3

recyclerView.layoutManager.scrollToPosition(0)

In your question you don't reference the recyclerview's layoutmanager but instead reference both the recylcerview and layoutmanager individually.

You much call recylcerview.layoutmanager
