java - 在滚动 RecyclerView 时出现异常 : -"java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position 21"

Question

我在我的应用程序中使用 RecyclerView 和 Sqlite。 因为我已经从 SQlite 加载了 RecyclerView 并且在后台调用服务后尝试通过 notifyDataSetChanged() 通知 RecyclerView 方法，但在滚动 RecyclerView 时出现意外异常(当 RecyclerView 正在更新或通知时)。​​

请检查我的 setAdapter()，我正在使用它通知并在 RecyclerView 上设置适配器

  private void setAdapter() {

        if (adapter == null) {
            adapter = new EmojiAdapter(stickerArrayList, getActivity(), "Sticker", stickerIdArrayList);
            RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getActivity());
            rvEmoji.setLayoutManager(mLayoutManager);
            rvEmoji.setItemAnimator(new DefaultItemAnimator());
            rvEmoji.setAdapter(adapter);
        } else {

            adapter.notifyDataSetChanged();

        }

    }

我已经尝试了所有的 RecyclerView.stopScroll(), RecyclerView.getRecycledViewPool().clear() 但问题不是短路

异常

我已经访问了所有链接并尝试了他们最好的解决方案，但它对我不起作用..

我正在为 RecyclerView 使用以下 gradle 版本

compile 'com.android.support:recyclerview-v7:26.+'

请检查我正在使用的适配器类如下:-

public class EmojiAdapter extends RecyclerView.Adapter<EmojiAdapter.MyViewHolder> {

    private Activity activity;
    private HashMap<String, ArrayList<EmojiBean>> arrayList = new HashMap<>();
    private String sticker_emoji;
    private ArrayList<String> keyArrayList = new ArrayList<>();

    public class MyViewHolder extends RecyclerView.ViewHolder {

        private RecyclerView rvItemCreation;
        private TextView txtStickerName, txtBy, txtCreator;
        private ImageView imgForward, imgDownload;

        private MyViewHolder(View view) {
            super(view);

            rvItemCreation = (RecyclerView) view.findViewById(R.id.rvItemCreation);
            txtStickerName = (TextView) view.findViewById(R.id.txtStickerName);
            txtBy = (TextView) view.findViewById(R.id.txtBy);
            txtCreator = (TextView) view.findViewById(R.id.txtCreator);
            imgForward = (ImageView) view.findViewById(R.id.imgForward);
            imgDownload = (ImageView) view.findViewById(R.id.imgDownload);

            txtStickerName.setTypeface(Constant.setCustomFont(activity, "Montserrat-SemiBold.otf"));
            txtBy.setTypeface(Constant.setCustomFont(activity, "Montserrat_Regular.otf"));
            txtCreator.setTypeface(Constant.setCustomFont(activity, "Montserrat_Regular.otf"));

        }
    }


    public EmojiAdapter(HashMap<String, ArrayList<EmojiBean>> arrayList, Activity activity, String sticker_emoji, ArrayList keyArrayList) {
        this.arrayList = arrayList;
        this.activity = activity;
        this.sticker_emoji = sticker_emoji;
        this.keyArrayList = keyArrayList;


    }


    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.my_media_item, parent, false);

        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {


        if (sticker_emoji.equalsIgnoreCase("Sticker")) {
            holder.imgForward.setImageResource(R.drawable.forward_icon);
        } else {
            holder.imgForward.setImageResource(R.drawable.delete_icon);
        }


        if (arrayList.size() > position) {
            MyCreationItemAdapter mAdapter = new MyCreationItemAdapter(arrayList.get(keyArrayList.get(position)), activity);
            RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(activity, LinearLayoutManager.HORIZONTAL, false);
            holder.rvItemCreation.setLayoutManager(mLayoutManager);
            holder.rvItemCreation.setItemAnimator(new DefaultItemAnimator());
            holder.rvItemCreation.setAdapter(mAdapter);
        }


    }

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


}

请帮我解决问题。谢谢

Update
What i have done to resolve this conflict that I have done disable user interface(Show some progress bar) while loading the data.

我对“java.lang.IndexOutOfBoundsException:检测到不一致。无效的项目位置 6(offset:6).state”有同样的问题。这个崩溃是用 pullrefrash 显示的，当你加载更多时，列表比你第一次加载的多。然后你 pulltorfrash 新数据并清除旧列表数据，此时你适配器的数据大小不超过你的新数据大小。
