错误膨胀类ImageView - android.view.InflateException：二进制XML文件行＃10：错误膨胀类ImageView

Question

我正在设计一个包含列表项xml文件的应用程序（list_item.xml）， 和listView（NewsAdapter.java）的适配器。

我的应用在运行时遇到此错误：

我的list_item文件有一个 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，该应用程序运行良好！

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>

Answer 1

在drawable中复制图像文件时，您将获得复制drawable和drawable-24的选项。确保你复制并尝试运行。

Answer 2

正如您在最后一行错误中看到的那样：

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

似乎你输入的东西不是你必须的尺寸。 并作为属性android:baseline的文档：

  

此视图中基线的偏移量。可能是维度值，   这是一个附加单位的浮点数，如   ＆＃34; 14.5sp＆＃34 ;.可用单位为：px（像素），dp（密度无关   像素），sp（基于首选字体大小的缩放像素），英寸（英寸），   和毫米（毫米）。

但是你使用了一个字符串作为基线值。

Answer 3

我的应用程序遇到了同样的问题，但最后我解决了这个问题。 只需将您的图像文件放在ic_launcher_background.xml文件而不是ic_launcher_foreground.xml文件中。希望它有所帮助。
