無法讀取rss XML，使用簡單的XML和翻新

Question

我已經搜索了很多，但是我無法將我的XML與My Classes一起分配，並且在嘗試反序列化XML時從改造中獲取錯誤。

這是我從我的接口（僅第一項）調用的XML：

<?xml version="1.0" encoding="UTF-8"?> 
<rss version="2.0" 
xmlns:content="http://purl.org/rss/1.0/modules/content/" 
xmlns:wfw="http://wellformedweb.org/CommentAPI/" 
xmlns:dc="http://purl.org/dc/elements/1.1/" 
xmlns:atom="http://www.w3.org/2005/Atom" 
xmlns:sy="http://purl.org/rss/1.0/modules/syndication/" 
xmlns:slash="http://purl.org/rss/1.0/modules/slash/"

所以我使用異步方法採取了回調的項目，這是Java接口：

這是正在生成的界面處的REST客戶端類：

public class RestClient { 

private ApiService apiService; 

public RestClient(){ 
    RestAdapter restAdapter = new RestAdapter.Builder() 
      .setLogLevel(RestAdapter.LogLevel.FULL) 
      .setClient(new OkClient(new OkHttpClient())) 
      .setEndpoint("http://flow.com") 
      .setConverter(new SimpleXMLConverter()) 
      .build(); 

    apiService = restAdapter.create(ApiService.class); 
} 

public ApiService getApiService(){ 
    return apiService; 
} 
} 

另外，我還創造了一些模型類從XML主辦的標籤，我省略吸氣劑：

@Root(name="rss", strict = false) 
public class Rss { 

    @Element(name="channel") 
    private Channel channel; 

} 
@Root(name = "item", strict = false) 
public class Item { 

@Element(name = "title") 
private String title; 
@Element(name = "link") 
private String link; 
@Element(name = "comments") 
private String comments; 
@Element(name = "pubDate") 
private String pubDate; 
} 

@Root(name="channel", strict = false) 
public class Channel { 

@ElementList(name="item",inline = true) 
private ArrayList<Item> items; 
} 

最後，我呼籲在MainActivity服務：

public class MainActivity extends AppCompatActivity { 

private ArrayList<Item> mList; 
private Button pagerButton; 
private int page = 0; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    pagerButton = (Button)findViewById(R.id.pager); 
    pagerButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 

      RestClient restClient = new RestClient(); 
      Callback<Channel> callback = new Callback<Channel>() { 
       @Override 
       public void success(Channel gadgets, Response response) { 
        mList = gadgets.getItems(); 
       } 

       @Override 
       public void failure(RetrofitError error) { 
        Log.d("billy",error.getLocalizedMessage()); 
       } 
      }; 
      restClient.getApiService().getGadgets(page,callback); 
        page++; 
     } 
    }); 

    if(mList != null) { 
     for(int i = 0; i < mList.size();i++) { 
      //mList = mItem.getGadgets(); 
      Log.d("billy", "Item : " + String.valueOf(i)); 
      Log.d("billy", "Title: " + mList.get(i).getTitle()); 
      Log.d("billy", "PubDate: " + mList.get(i).getPubDate()); 
      Log.d("billy", "ImageURL: " + mList.get(i).getLink()); 
      Log.d("billy","-------------------------------------------------------------------- "); 
     } 
    } 

} 
} 

所以，我把這個錯誤從改造：

org.simpleframework.xml.core.ValueRequiredException：無法滿足@ org.simpleframework.xml.ElementList（數據=假，空=真，進入=，=內嵌真正的，名稱=項目，在f上需要= true，type = void） ield「項目」在行9

私人的java.util.ArrayList Model.Channel.items類Model.Channel我已經搜索無處不在，我覺得我的實施是正確的，但我找不到錯誤，我改變了很多次我的Model類，並且使用了Web上的POJO生成器，但是我無法修復這個錯誤。請幫忙！謝謝！

最終我改變了我的回調，它工作。我不得不使用模型類RSS回調例如：

public interface ApiService { 
    @GET("/?feed=single_gallery_feed") 
    void getGadgets(@Query("paged")int page, Callback<Rss> gadgetsCallback); 
} 

而且裏面MainActivity回調：

RestClient restClient = new RestClient(); 
     Callback callback = new Callback() { 
      @Override 
      public void success(Object o, Response response) { 
       Categories_ = (Categories)o; 
      } 

      @Override 
      public void failure(RetrofitError error) { 
       Toast toast = Toast.makeText(getApplication(), "Something went wrong!!", Toast.LENGTH_SHORT); 
       toast.show(); 
      } 
     }; 
     restClient.getApiService().getCategories(callback);
