Ich habe überall gesucht und versucht, Beispiele zu folgen, aber ich kann SharedPreferences nicht implementieren.ImageView basierend auf SharedPreference
Ich erstelle eine sehr niedrige PunchCard. NFCTag hat ein Textfeld, das "Kaffee" sagt. Ich habe ein anderes, das "Sandwich" sagt. Ich habe dann 2 Strings mit dem gleichen Namen. Tippe auf das Kaffee-Etikett, es ändert das Kaffee-Bild, Tippe auf das Sandwich-Etikett, es ändert das Sandwich-Bild.
jetzt meine Frage ... Ich bin in der Lage, es zu erhalten, die Einstellung zu speichern, aber es ist das Bild nicht aktualisiert, würden irgendwelche Vorschläge geschätzt werden ..
https://github.com/soboapps/PunchCard - Das Sie eine Vorstellung davon geben kann, was Ich versuche es zu tun.
Hier ist mein Code (Ich weiß, es ist ein Chaos)

Ich aktualisierte den obigen Code .. Ich glaube, es speichert jetzt den True oder False Wert, aber jetzt aktualisiert es die Bilder nicht. Übrigens, die Bilder, die ich zu aktualisieren versuche, sind in coffee_fragment.xml und nicht in der Datei main_activity.xml, aber ich versuche alles über die MainActivity zu machen. Alles sieht gut aus, und ich bekomme keine Fehler, es aktualisiert die Bilder einfach nicht. Jede Hilfe wäre willkommen. – Sobo
Während ich das + (Iterator) immer noch nicht verstehe, konnte ich Ihre Antwort anpassen und die Dinge funktionieren großartig. Vielen Dank – Sobo
