Fehler beim Aufblasen der Klasse ImageView - Android.view.InflateException: Binäre XML-Dateizeile # 10: Fehler beim Aufblasen der Klasse ImageView
Ich entwerfe eine App, die eine XML-Datei für die Listenelemente (list_item.xml), Und einen Adapter für die Listenansicht (NewsAdapter.Java) enthält.
Meine App stößt bei der Ausführung auf diesen Fehler:

Meine list_item-Datei hat eineImageView:
<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" />
Wenn ich ImageView aus der list_item.xml lösche, läuft die App gut!
Was soll ich machen?!
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"

Wie Sie in den letzten Fehlerzeilen sehen:
Caused by: Java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x12
anscheinend haben Sie etwas eingegeben, bei dem es sich nicht um eine Dimension handelt, in der Sie ... und als Dokumentation des Attributs Android:baseline:
Der Versatz der Grundlinie innerhalb dieser Ansicht. Kann ein Dimensionswert sein Hierbei handelt es sich um eine Fließkommazahl, an die eine Einheit angehängt wird, z. "14.5sp". Verfügbare Einheiten sind: px (Pixel), dp (dichteunabhängige Pixel), sp (skalierte Pixel basierend auf der bevorzugten Schriftgröße), in (Zoll), und mm (Millimeter).
Sie haben jedoch eine Zeichenfolge als Basiswert verwendet.
beim Kopieren der Bilddateien in drawable können Sie sowohl in drawable als auch drawable-24 kopieren. Stellen Sie sicher, dass Sie in beide kopieren und dann versuchen, sie auszuführen.
Ich hatte das gleiche Problem mit meiner Anwendung, aber schließlich habe ich es gelöst .. __ Legen Sie einfach Ihre Bilddatei in die Datei ic_launcher_background.xml anstelle der Datei ic_launcher_foreground.xml.
