Java E/RecyclerView：未连接适配器；正在跳过布局。。。更新了更多的类

请原谅我两天前试图解决这个问题。。我看到了网站上提供的大多数解决方案，但没有人解决我的问题

应用程序已停止，我收到以下错误：E/RecyclerView:未连接适配器；跳过布局

以下是我的主要活动：

public class MainActivity extends AppCompatActivity {

    RecyclerView listWebsite;
    RecyclerView.LayoutManager layoutManager;
    NewsService mService;
    ListSourceAdapter adapter;
    AlertDialog dialog;
    SwipeRefreshLayout swipeLayout;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        swipeLayout = (SwipeRefreshLayout)findViewById(R.id.swipeRefresh);
        swipeLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                loadWebsiteSource(true);
            }
        });

        Paper.init(this);
        mService = Common.getNewsService();
        listWebsite = (RecyclerView)findViewById(R.id.list_source);
        listWebsite.setHasFixedSize(true);
        layoutManager = new LinearLayoutManager(this);
        listWebsite.setLayoutManager(layoutManager);

        dialog = new SpotsDialog(this);

        loadWebsiteSource(true);



    }

    private void loadWebsiteSource(boolean isRefreshed) {
        if(!isRefreshed)
        {
            String cache = Paper.book().read("cache");
            if(cache != null && !cache.isEmpty())
            {
                // Convert cache from Json to Object
                WebSite website = new Gson().fromJson(cache, WebSite.class);
                adapter = new ListSourceAdapter(getBaseContext(), website);
                adapter.notifyDataSetChanged();
                listWebsite.setAdapter(adapter);

            }
            else
            {
                dialog.show();

                mService.getSources().enqueue(new Callback<WebSite>() {
                    @Override
                    public void onResponse(Call<WebSite> call, Response<WebSite> response) {

                        adapter = new ListSourceAdapter(getBaseContext(), response.body());
                        adapter.notifyDataSetChanged();
                        listWebsite.setAdapter(adapter);

                        Paper.book().write("cache", new Gson().toJson(response.body()));
                    }

                    @Override
                    public void onFailure(Call<WebSite> call, Throwable t) {

                    }
                });
            }
        }
        else
        {
            dialog.show();

            mService.getSources().enqueue(new Callback<WebSite>() {
                @Override
                public void onResponse(Call<WebSite> call, Response<WebSite> response) {

                    adapter = new ListSourceAdapter(getBaseContext(), response.body());
                    adapter.notifyDataSetChanged();
                    listWebsite.setAdapter(adapter);

                    Paper.book().write("cache", new Gson().toJson(response.body()));

                    swipeLayout.setRefreshing(false);
                }

                @Override
                public void onFailure(Call<WebSite> call, Throwable t) {

                }
            });
        }
    }
}

这是我的适配器：

class ListSourceViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{

    ItemClickListener itemClickListener;

    TextView source_title;
    CircleImageView source_image;

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

        source_image = (CircleImageView)itemView.findViewById(R.id.source_image);
        source_title = (TextView)itemView.findViewById(R.id.source_name);
    }

    public void setItemClickListener(ItemClickListener itemClickListener){
        this.itemClickListener = itemClickListener;
    }

    @Override
    public void onClick(View view) {

    }
}

public class ListSourceAdapter extends RecyclerView.Adapter<ListSourceViewHolder>{

    private Context context;
    private WebSite webSite;
    private IconBetterIdeaService mService;

    public ListSourceAdapter(Context baseContext, WebSite website) {
        this.context = baseContext;
        this.webSite = website;

        mService = Common.getIconService();
    }

    @Override
    public ListSourceViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        View itemView = inflater.inflate(R.layout.source_layout, parent, false);
        return new ListSourceViewHolder(itemView);
    }


    @Override
    public void onBindViewHolder(final ListSourceViewHolder holder, int position) {
        StringBuilder iconBetterApi = new StringBuilder("https://icons.better-idea.org/allicons.json?url=");
        iconBetterApi.append(webSite.getSources().get(position).getUrl());

        mService.getIconUrl(iconBetterApi.toString())
                .enqueue(new Callback<IconBetterIdea>() {
                    @Override
                    public void onResponse(Call<IconBetterIdea> call, Response<IconBetterIdea> response) {
                        if(response.body().getIcons().size() > 0)
                        {
                            Picasso.with(context)
                                    .load(response.body().getIcons().get(0).getUrl())
                                    .into(holder.source_image);
                        }
                    }

                    @Override
                    public void onFailure(Call<IconBetterIdea> call, Throwable t) {

                    }
                });

        holder.source_title.setText(webSite.getSources().get(position).getName());
        holder.setItemClickListener(new ItemClickListener() {
            @Override
            public void onClick(View view, int position, boolean isLongClick) {

            }
        });
    }


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

以下是网站课程：

public class WebSite {
    private String status;
    private List<Source> sources;

    public WebSite() {

    }

    public WebSite(String status, List<Source> sources) {
        this.status = status;
        this.sources = sources;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public List<Source> getSources() {
        return sources;
    }

    public void setSources(List<Source> sources) {
        this.sources = sources;
    }
}

下面是源类：

public class Source {

    private String id;
    private String name;
    private String description;
    private String url;
    private String category;
    private String language;
    private String country;
    private UrlsToLogos urlsToLogos;
    private List<String> sortBysAvailable;

    public Source() {
    }

    public Source(String id, String name, String description, String url, String category, String language, String country, UrlsToLogos urlsToLogos, List<String> sortBysAvailable) {
        this.id = id;
        this.name = name;
        this.description = description;
        this.url = url;
        this.category = category;
        this.language = language;
        this.country = country;
        this.urlsToLogos = urlsToLogos;
        this.sortBysAvailable = sortBysAvailable;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public String getCategory() {
        return category;
    }

    public void setCategory(String category) {
        this.category = category;
    }

    public String getLanguage() {
        return language;
    }

    public void setLanguage(String language) {
        this.language = language;
    }

    public String getCountry() {
        return country;
    }

    public void setCountry(String country) {
        this.country = country;
    }

    public UrlsToLogos getUrlsToLogos() {
        return urlsToLogos;
    }

    public void setUrlsToLogos(UrlsToLogos urlsToLogos) {
        this.urlsToLogos = urlsToLogos;
    }

    public List<String> getSortBysAvailable() {
        return sortBysAvailable;
    }

    public void setSortBysAvailable(List<String> sortBysAvailable) {
        this.sortBysAvailable = sortBysAvailable;
    }
}

我正在使用newsapi.org api检索新闻来源。

请阅读错误消息。。。您没有将适配器连接到RecyclerView。在一些执行路径中，您只在稍后执行的回调中添加适配器。确保您正在为所有条件设置适配器，然后在收到响应后更新传递到适配器中的网站数据

我认为您对loadWebsiteSource的else语句看起来像：

else
{
    dialog.show();

    website = new WebSite(); //Whatever this object is
    adapter = new ListSourceAdapter(getBaseContext(), website);
    listWebsite.setAdapter(adapter)

    mService.getSources().enqueue(new Callback<WebSite>() {
        @Override
        public void onResponse(Call<WebSite> call, Response<WebSite> response) {
            website.update(response.body());
            adapter.notifyDataSetChanged();

            Paper.book().write("cache", new 
            Gson().toJson(response.body()));

            swipeLayout.setRefreshing(false);
        }

        @Override
        public void onFailure(Call<WebSite> call, Throwable t) {

        }
    });
}

谢谢你，谢谢你。。但是你能解释一下如何实现更新方法吗？什么是网站对象？我叫它update的意思是，不要实例化一个新的网站对象，而是更新它的数据。。提前感谢我根据这些课程更新了我的回复。您可以通过其他方式来实现，其想法是您不希望在活动中创建对网站变量的新引用，因为适配器也使用相同的引用，所以您希望更新数据。

public void update(WebSite newWebSiteData){
    this.sources.clearAll();
    this.sources.addAll(newWebSiteData.getSources());
    this.sources.setStatus(newWebSiteData.getStatus());
}
