我正在設計一個應用程序,它有一個列表項目(list_item.xml)的xml文件, 和一個適配器爲listView(NewsAdapter.java)。錯誤膨脹類ImageView - android.view.InflateException:二進制XML文件行#10:錯誤膨脹類ImageView

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" /> 

當我從list_item.xml刪除ImageView的,該應用程序運行

我的應用程序運行的時候遇到這個錯誤好!

我該怎麼辦?

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"

    tools:ignore="NotSibling" />

爲什麼不把'ImageView'放在'RelativeLayout'裏面? – Journey

在xml中不能有多個根標籤。把imageView放在relativeLayout裏面。 –

正如你在錯誤的最後幾行看:

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

似乎你輸入的東西不是必須的維度。 而作爲屬性android:baseline的文檔:

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).

但是你使用的基線值的字符串。

在複製可繪製的圖像文件時,您將可以選擇複製drawable和drawable-24。確保你同時複製,然後嘗試運行。

標題中的錯誤與錯誤的XML結構有關,而不是可繪製的。 –

我和我的應用程序有同樣的問題,但最後我解決了它。 只需將您的映像文件放在ic_launcher_background.xml文件中,而不是ic_launcher_foreground.xml文件中。希望它有幫助。
