Beim Hinzufügen von Hintergrundbild: Fehler beim Aufblasen der Klasse android.widget.ImageButton

Sind Sie sicher, dass 'musicoff' in Ihrem aufklappbaren Ordner vorhanden ist? –

ja, es ist in meinem Zeichnungsordner als .png – 1QuickQuestion

Ihr Bild haben große Größe. Versuchen Sie, das Bild zu skalieren. –

Ich habe den Code ausprobiert und es funktioniert für mich. Also ich denke, Ihr Problem ist Ihre musicoff Zeichnungsfähig und genau die Größe davon.

Versuchen Sie, diese Zeichengröße zu ändern oder versuchen Sie es mit einem anderen Zeichenbild und es wird funktionieren.

dd Sie ändern die Größe? oder etwas ändern? – 1QuickQuestion

Ich versuche einen anderen Zeichensatz. In der Tat hatte ich vorher das gleiche Problem. Versuchen Sie es mit einem anderen Zeichensatz oder ändern Sie die Zeichengröße. Lässt mich wissen, ob es funktioniert –

Ich bekomme immer noch den gleichen Fehler. Wie groß ist die Größe der Datei, die Sie verwenden? – 1QuickQuestion
