我LIST_ITEM文件具有ImageView的：

<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删除ImageView的，该应用程序运行

我的应用程序运行的时候遇到这个错误好！

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>

发布完整的list_item.xml – phpdroid

为什么不把'ImageView'放在'RelativeLayout'里面？ – Journey

在xml中不能有多个根标签。把imageView放在relativeLayout里面。 –

答

正如你在错误的最后几行看：

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

似乎你输入的东西不是必须的维度。而作为属性android:baseline的文档：

The offset of the baseline within this view. May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

但是你使用的基线值的字符串。

答

在复制可绘制的图像文件时，您将可以选择复制drawable和drawable-24。确保你同时复制，然后尝试运行。

标题中的错误与错误的XML结构有关，而不是可绘制的。 –

答

我和我的应用程序有同样的问题，但最后我解决了它。只需将您的映像文件放在ic_launcher_background.xml文件中，而不是ic_launcher_foreground.xml文件中。希望它有帮助。
