So versuche ich eine zweite Aktivität von der ersten Aktivität von einem Klick auf eine Schaltfläche zu öffnen. Die App wird geladen, aber wenn ich versuche, den Knopf zu drücken, um zur nächsten Aktivität zu gehen, passiert nichts. Hier sind meine main.xml, mainactivity.java, androidmanifest.xml, shopactivity.java und shop.xml. Jede Hilfe wird sehr geschätzt.Erfolglose Eröffnung zweite Aktivität
