You can use for Next button:

mRecyclerView.getLayoutManager().scrollToPosition(linearLayoutManager.findLastVisibleItemPosition() + 1);

And for Previous Button:

mRecyclerView.getLayoutManager().scrollToPosition(linearLayoutManager.findFirstVisibleItemPosition() - 1);

Have look this

You can have a variable that tracks the current displayed position of the RecyclerView, named it "currentPosition" in below snippets

Then increment it if you want to navigate to the next item as follows:

private void scrollToNext() {
    if ((recyclerView.getLayoutManager()) != null) {
        ((LinearLayoutManager) recyclerView.getLayoutManager()).scrollToPositionWithOffset(currentPosition++, 0);
    }
}

You can use RelativeLayout or the custom layout instead of LinearLayout; according to what you're using in your RecyclerView

Similarly, decrement it if you want the previous one

private void scrollToPrevious() {
    if ((recyclerView.getLayoutManager()) != null) {
        ((LinearLayoutManager) recyclerView.getLayoutManager()).scrollToPositionWithOffset(currentPosition--, 0);
    }
}
