Der folgende App-Code, auf dem ich arbeite, zeigt ein Dialogfeld, wo ich wählen kann, um ein Foto oder ein Bild aus einer Galerie zu wählen.Hier funktioniert der Kamera-Code aber gut Wenn es um die Bildauswahl aus der Galerie geht, zeigt es nicht das Bild in meiner Bildansicht an, das ich ausgewählt habe. Bitte versuchen Sie mich über diese Hürde zu löschen? `Bildauswahl aus der Galerie und fotografieren in Android App
