我有一个recyclerView，每个项目都是一个recyclerView。我想在特定条件下滚动到内部recyclerView的自定义位置。我在innerRecyclerView上使用了这段代码，但是没有用：

innerRecyclerView.smoothScrollToPosition(position); 

和这个：

innerRecyclerView.scrollToPosition(position); 

还有这个：

layoutManager.scrollToPositionWithOffset(position, offset);

现在我有两个问题：

1）是否可以滚动到内部recyclerView的自定义位置？

2）如果可能的话，怎么办？

这是初始化主recyclerView：

LinearLayoutManager layoutManager = new LinearLayoutManager(getContext(), RecyclerView.VERTICAL, false);
        adapter = new FreightsListRVAdapter(new FreightListCallBack(), new FreightListVHFactory());
        rvFreightsList.setLayoutManager(layoutManager);
        rvFreightsList.setItemViewCacheSize(30);
        rvFreightsList.setNestedScrollingEnabled(true);
        rvFreightsList.setAdapter(adapter);

这是初始化innerRecyclerview：

LinearLayoutManager layoutManager = new LinearLayoutManager(itemView.getContext(), RecyclerView.VERTICAL, false);
        layoutManager.setItemPrefetchEnabled(true);
        layoutManager.setInitialPrefetchItemCount(7);
        rvFreights.setNestedScrollingEnabled(false);
        rvFreights.setLayoutManager(layoutManager);
        rvFreights.setItemViewCacheSize(20);

        adapter = new FreightsRVAdapter(new FreightCallBack(), new FreightSingleVHFactory());
        rvFreights.setAdapter(adapter);

这是我的主要recyclerView适配器：

public class FreightsListRVAdapter extends ListAdapter<FreightListModel, FreightListVH> {

    private final FreightListVHFactory mFactory;
    private final PublishSubject<FreightListVHAction> mClickUserPS = PublishSubject.create();

    @Inject
    public FreightsListRVAdapter(@NonNull FreightListCallBack diffCallback, FreightListVHFactory factory) {
        super(diffCallback);
        mFactory = factory; …
