Ich versuche nun seit mehr als einer Woche den Fehler im Spinner zu finden und komm nicht weiter. Das ist mein erstes Projekt. Ich mach das immer erst mal um ein Gefühl für die Umgebung zu bekommen. Also habe ich im Vids geschaut und versucht daraus eine Lösung zu entwickeln.
Hier mein Problem.
Ich habe einen Spinner mit Custom Adapter nachgebaut. Leider bekomme ich keine Anzeige im Textteil. Der DropDown funktioniert, speichert aber keine Werte. Ich weiß echt nicht mehr wo ich kontrollieren soll.
Also jetzt einmal die Activity und der Adapter:
