我正在尝试使用Retrofit下载XML数据并使用Simple解析它,然后将其加载到ListView中.

不幸的是,下载的数据不会出现在屏幕上 有人能告诉我问题出在哪里吗？

这是我的模特:

@Root(name = "item")
public class Article {
    @Element(name = "title")
    private String title;
    @Element(name = "author")
    private String author;
    @Element(name = "description")
    private String description;

接口代码:

public interface Service {
    @GET("/rss/news")
    public void getArticle(Callback<List<Article>> callback);
}

片段代码:

public class ArticlePreviewFragment extends Fragment {

    protected ArticlePreviewAdapter adapter;
    protected List<Article> previewList;
    private ListView listView;

    public ArticlePreviewFragment() {}

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        previewList = new ArrayList<>();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) …
