articleList.setAdapter(bindingData); 引发致命异常 (Resources$NotFoundException)。

我正在尝试从片段中填充 ListView。如果它位于 ListView 位于 Activity 上的单独项目中，则相同的代码可以工作。我所做的唯一更改是将以下构造函数添加到 BinderData 类：

    public BinderData(LayoutInflater i, List<HashMap<String, String>> map) {
    this.contentDataCollection = map;
    inflater = i;
}

片段：

public static class CalendarFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.calendar_fragment, container, false);

        final ListView articleList = (ListView)view.findViewById(R.id.content_list);
        final List<HashMap<String, String>> contentDataCollection = new ArrayList<HashMap<String, String>>();
        HashMap<String, String> map = null;

        map = new HashMap<String, String>();
        map.put("type", "Article");
        map.put("title", "Gesund kochen");
        map.put("text", "Lorem ipsum");
        map.put("image", "img_10061216.jpg");
        contentDataCollection.add(map);

        map = new HashMap<String, String>();
        map.put("type", "Rezept");
        map.put("title", "Pasta mit Radicchio");
        map.put("text", "300g Pasta");
        map.put("image", "img_10061216.jpg");
        contentDataCollection.add(map);

        BinderData bindingData = new BinderData(inflater, contentDataCollection);
        articleList.setAdapter(bindingData);

        return view;
    }
}

getDrawablethrows Resources$NotFoundException，如果您提供的 id 不存在。

String uri = "drawable/" + contentDataCollection.get(position).get(KEY_IMAGE);
int imageResource = vi.getContext().getApplicationContext().getResources().getIdentifier(uri,null,vi.getContext().getApplicationContext().getPackageName());

在这里，您正在寻找可绘制对象的 id，但如果您要查找的可绘制对象不存在，getIdentifier 可以返回 0。试试这种方式：

String drawableName = "the_name_of_drwable"; resId = getContext().getResources().getIdentifier(drawableName, "drawable", getContext().getPackageName())

只需将vi = inflater.inflate(R.layout.list_row, null);您的 getView 方法的这一行更改为：vi = inflater.inflate(R.layout.list_row, parent, false);。这是因为您必须指定一个父级，并且不要让他们附加根它。
