我是一名可以翻译文本的助手。

我正在设计一个应用程序，其中有一个xml文件用于列表项（list_item.xml），以及listView的适配器（NewsAdapter.java）。

我的应用程序在运行时遇到了这个错误：

我的list_item文件中有一个ImageView：

<ImageView
    android:id="@+id/thumbnail"
    android:layout_width="40dp"
    android:layout_height="wrap_content"
    android:baseline="@id/title"
    app:srcCompat="@android:drawable/ic_lock_lock"
    tools:ignore="NotSibling" />

当我从list_item.xml中删除ImageView时，应用程序运行良好！

我该怎么办？！

NewsAdapter.java：

public class NewsAdapter extends ArrayAdapter {
    Context context;
    List<News> newsList;

    public NewsAdapter(@NonNull Context context, @LayoutRes int resource, @NonNull List objects) {
        super(context, resource, objects);
        this.context = context;
        this.newsList = objects;
    }

    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        News current_news = (News) getItem(position);
        View list_view = convertView;
        if(list_view == null) {
            list_view = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
        }

        TextView title = list_view.findViewById(R.id.title);
        TextView publicationDate = list_view.findViewById(R.id.publicationDate);
        TextView publication = list_view.findViewById(R.id.publication);

        title.setText(current_news.getTitle());
        publicationDate.setText(current_news.getPublication_date());
        publication.setText(current_news.getPublication());

        return list_view;
    }
}

list_item.xml:

<ImageView
    android:id="@+id/thumbnail"
    android:layout_width="40dp"
    android:layout_height="wrap_content"
    android:baseline="@id/title"
    app:srcCompat="@android:drawable/ic_lock_lock"
    tools:ignore="NotSibling" />

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="16dp">

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:ellipsize="end"
        android:maxLines="3"
        tools:text="Is technology delivering in schools? Our panel debates" />

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/title"
        android:layout_alignParentLeft="true"
        android:orientation="horizontal">

        <TextView
            android:id="@+id/publicationDate"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            tools:text="27 Nov, 2016" />

        <TextView
            android:id="@+id/pipe_icon"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/separator_icon" />

        <TextView
            android:id="@+id/publication"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:ellipsize="end"
            android:maxLines="1"
            tools:text="The Guardian" />
    </LinearLayout>

</RelativeLayout>

请发布您的完整list_item.xml文件。 - phpdroid
为什么不把那个 ImageView 放到 RelativeLayout 里面呢？ - Niraj Niroula
在 XML 中不能有多个根标签。将 imageView 放在 relativeLayout 中。 - Praveen Singh

当你在复制drawable中的图像文件时，你会得到复制到drawable和drawable-24两个选项。确保你都复制了，然后再尝试运行。

标题中的错误与错误的XML结构有关，而不是与可绘制对象相关。 - Клаус Шварц

正如错误的最后几行所示:

Caused by: java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x12

看起来您输入了一个不是dimension的东西。

而且在android:baseline 属性的文档中：

这个视图中基线的偏移量。可以是尺寸值， 尺寸值是一个浮点数，附加有单位，例如  “14.5sp” 。可用单位为：px（像素），dp（密度无关像素）， sp（按首选字体大小缩放的像素），in（英寸）， 和mm（毫米）。

但您使用了一个字符串作为基线的值。

我曾经遇到过同样的问题，但最终我解决了它。只需将您的图像文件放入ic_launcher_background.xml文件中，而不是ic_launcher_foreground.xml文件中即可。希望能对您有所帮助。
