Android recyclerview scroll to position

Question

Public class spinFragment extends AbstractSpinningFragment {

Context context;
private ExpandableAdapter expandableAdapter;

@BindView(R.id.recycler)
RecyclerView recyclerView;

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    final View fragmentView = inflater.inflate(R.layout.fragmentSpin, container, false);

    this.sectionWebContentRecyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
    recyclerView.setAdapter(this.expandableAdapter);

    recyclerView.scrollToPosition(10);

    return fragmentView;
}

I want to scroll to position 10 in my recyclerview. But it doesn't do anything.

I also tried: recyclerView.getLayoutManager().scrollToPosition(12); and smooth scrolling.

Anyone knows that the problem is?
