RecyclerView滚动条滞后

Question

当我使用新的回收器视图时,我注意到滚动条不像常规ScrollView/ListView那样流畅.在适配器项目中滚动时,它似乎无法识别,但只有在新项目出现/旧项目消失时才会更改,因此进度条会跳转而不是平滑移动.这是一个展示此问题的视频.有没有办法使它顺利？

我的布局:

<android.support.v7.widget.RecyclerView
                android:id="@+id/listRecycler"
                android:scrollbars="vertical"
                android:layout_width="match_parent"
                android:layout_height="match_parent"/>

分段:

    mListRecycler.setAdapter(mAdapter);
    LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
    layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
    mListRecycler.setLayoutManager(layoutManager);

适配器:

public class NewsAdapter extends RecyclerView.Adapter<NewsAdapter.ViewHolder> {

private List<News> items;
private int itemLayout;

public NewsAdapter(List<News> items, int itemLayout) {
    this.items = items;
    this.itemLayout = itemLayout;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View v = LayoutInflater.from(parent.getContext()).inflate(itemLayout, parent, false);
    v.setOnClickListener(this);
    return new ViewHolder(v);
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    News item = items.get(position);
    holder.text.setText(item.getTitle());
    holder.itemView.setTag(item);
}


@Override
public int getItemCount() {
    return items.size();
}

public static class ViewHolder extends RecyclerView.ViewHolder {
    @InjectView(R.id.title)
    TextView text;

    public ViewHolder(View itemView) {
        super(itemView);
        ButterKnife.inject(this, itemView);
    }
}

}

这是 L 预览版中的问题。LinearLayoutManager 没有平滑滚动条支持。将在 RecyclerView 发布时修复。
