滚动滚动获取RecyclerView异常：-“ java.lang.IndexOutOfBoundsException：检测到不一致。 无效的商品位置21”
[英]On scroll the RecyclerView getting exception : -“ java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position 21”
问题描述
I am using the RecyclerView with Sqlite in my app. 
我在我的应用程序中将RecyclerView与Sqlite一起使用。 As i have load the RecyclerView from the SQlite and than after call service in background and try to notify the RecyclerView by notifyDataSetChanged() method but getting the unexpected exception while scrolling the RecyclerView ( when RecyclerView is updating or notifying). 因为我已经从SQlite加载了RecyclerView ，并且比在后台调用服务之后加载了尝试，并尝试通过notifyDataSetChanged()方法通知RecyclerView ，但是在滚动RecyclerView时遇到意外异常（当RecyclerView正在更新或通知时）。
Please check my setAdapter() which i am using to notify and set the adapter on RecyclerView 请检查我用于通知的setAdapter()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();
}
}
I have tried all RecyclerView.stopScroll() , RecyclerView.getRecycledViewPool().clear() but problem is not short out 我已经尝试了所有RecyclerView.stopScroll() ， RecyclerView.getRecycledViewPool().clear()但问题并不出局
Exception 例外
java.lang.IndexOutOfBoundsException: Inconsistency detected.

I am using the following gradle version for the RecyclerView 我正在为RecyclerView使用以下gradle版本
compile 'com.android.support:recyclerview-v7:26.+'
Please check the Adapter class which i am using as follow:- 请检查我正在使用的Adapter类，如下所示：
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();
}
}
Please help me to short out from the problem.Thanks 请帮助我解决问题。谢谢

I had the same question with "java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position 6(offset:6).state". 我对“ java.lang.IndexOutOfBoundsException：检测到不一致。项目位置6（offset：6）.state无效”存在相同的问题。 This crash is show with pullrefrash , when you had loadmore the list is more than you first loaded . 使用pullrefrash显示此崩溃，当您加载了更多信息时，该列表的数量便超过了首次加载的数量。 then you pulltorfrash new data and clear the old list data ,at this moment you adapter's data size is not more than you new data size. 然后您将新数据拖出并清除旧列表数据，此时适配器的数据大小不超过新数据大小。

Try commenting this line of code: 尝试注释以下代码行：
rvEmoji.setItemAnimator(new DefaultItemAnimator());
Check if it works now. 检查现在是否可以使用。 If it does then the error you faced is because the PredictiveAnimations are enabled. 如果确实如此，那么您面临的错误是因为启用了PredictiveAnimations。 To use your code with animation you'll have to subclass the specific layout manager that you are using and override the supportsPredictiveItemAnimations() method and return false. 要将代码与动画一起使用，您必须将正在使用的特定布局管理器子类化，并覆盖supportsPredictiveItemAnimations（）方法并返回false。
@Override
public boolean supportsPredictiveItemAnimations() {
return false;
}
