RecyclerView带两个适配器; ClassCastException异常

Question

目前我正在制作一个新闻阅读器应用程序 1 - 最新消息 2 - 未读新闻

基本上我的Recyclerview有两个适配器，一个用于最新消息，另一个用于未读消息。现在，未读新闻适配器只是我的副本，看看它是如何表现的，一旦我确定适配器工作，我将对未读新闻进行排序。最近的适配器工作正常，但当我点击并运行未读适配器时，它给了我这个错误：

11-09 06:16:11.766 2534-2534/? E/AndroidRuntime: FATAL EXCEPTION: main

                                             java.lang.ClassCastException: com.example.azrie.dummyvoice.RecyclerView_Adapter_RecentNews$ViewHolder cannot be cast to com.example.azrie.dummyvoice.RecyclerView_Adapter_UnreadNews$ViewHolder

这是我最近的新闻适配器类：

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

ArrayList<Store_News_XML> newsXML;
Context context;

public RecyclerView_Adapter_RecentNews(Context context, ArrayList<Store_News_XML> newsXML){
    this.context = context;
    this.newsXML = newsXML;
    //this.recyclerView = recyclerView;
}


public static class ViewHolder extends RecyclerView.ViewHolder {
    // each data item is just a string in this case
    TextView text_title;
    TextView text_description;
    TextView text_date;
    View view;
    String currentLink;


    public ViewHolder(View itemView) {
        super(itemView);

        text_title = (TextView) itemView.findViewById(R.id.title_text_r);
        text_description = (TextView) itemView.findViewById(R.id.title_description_r);
        text_date = (TextView) itemView.findViewById(R.id.date_text_r);


        view = itemView;

        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

            }
        });

    }

}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(context).inflate(R.layout.recycler_view_card,parent,false);
    final ViewHolder holder = new ViewHolder(view);
    view.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            newsXML.get(holder.getLayoutPosition()).setRead(true);

            /*for(int i = 0; i < newsXML.size(); i++){
                Log.d("News " + i + " ", " "+ newsXML.get(i).getRead() );
            }*/

            Intent intent = new Intent(view.getContext(),Activity_WebView.class);

            Bundle bundle = new Bundle();
            bundle.putParcelableArrayList("link", newsXML);
            bundle.putInt("position",holder.getLayoutPosition());

            intent.putExtra("bundle",bundle);
            view.getContext().startActivity(intent);


        }
    });

    return holder;
}

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

    Store_News_XML current = newsXML.get(position);

    holder.text_title.setText(current.getTitle());
    holder.text_description.setText(current.getDescription());
    holder.text_date.setText(current.getPubDate());
    holder.currentLink = current.getLink();

   // Log .d("News Read Outside " + position ,"" + current.getRead() + " / News Title : " + current.getTitle());
    if(!newsXML.get(position).getRead()){
        //Log .d("News Not Read " + position ,"" + current.getRead() + " / News Title : " + current.getTitle());
        holder.text_title.setTextColor(Color.parseColor("#000000"));
        holder.text_description.setTextColor(Color.parseColor("#000000"));
        holder.text_date.setTextColor(Color.parseColor("#000000"));
    }
    else
    {
        //Log .d("News Read " + position ,"" + current.getRead() + " / News Title : " + current.getTitle());
        holder.text_title.setTextColor(Color.parseColor("#BAC1C1"));
        holder.text_description.setTextColor(Color.parseColor("#BAC1C1"));
        holder.text_date.setTextColor(Color.parseColor("#BAC1C1"));
    }

}

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



}

这是我的未读新闻适配器类：

        view.setOnClickListener(new View.OnClickListener() {
            @Override

}

我很抱歉凌乱且非结构化的代码，我对编程很新。感谢您提前获得所有帮助。
