(Smooth)ScrollToPosition doesn't work properly with RecyclerView

Question

I\'m using basic RecyclerView with GridLayoutManager. I observed that nor smoothScrollToPosition nor scrollToPosition works properly.

a) when using smoothScrol

Answer 1

This extension is so useful, try please.

fun RecyclerView.smoothSnapToPosition(position: Int, snapMode: Int = LinearSmoothScroller.SNAP_TO_START) {
        val smoothScroller = object : LinearSmoothScroller(this.context) {
            override fun getVerticalSnapPreference(): Int = snapMode
            override fun getHorizontalSnapPreference(): Int = snapMode
        }
        smoothScroller.targetPosition = position
        layoutManager?.startSmoothScroll(smoothScroller)
    }

Answer 2

recyclerView.getLayoutManager().smoothScrollToPosition(recyclerView,new RecyclerView.State(),currentPosition);

Answer 3

Another reason why any of the before mentioned solutions may not work is if your RecyclerView is embedded in a NestedScrollView. In this case you have to call the scroll action on the NestedScrollView.

for example:

nestedScrollview.smoothScrollTo(0,0)

Answer 4

If you are trying to do a quick scroll to a position at the top of the RecyclerView, just use LinearLayoutManager.scrollToPositionWithOffset with 0 as the offset.

Example:

mLinearLayoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(mLinearLayoutManager);

mLinearLayoutManager.scrollToPositionWithOffset(myPosition, 0);

smoothScrollToPosition is very slow. If you want something fast go with scrollToPositionWithOffset.
