Ich versuche eine Volley-Anfrage zu senden, um Recyclerviews zu füllen, aber aus irgendeinem Grund, den ich ergründen kann, ist die Recycleransicht nicht ausgefüllt. Die Daten sind recht gut geholt, das kann ich vom Logcat sehen.RecyclerView wird nicht mit Elementen gefüllt
Nach dem Laden sehe ich nur eine leere Seite, leere und leere Seite.
Das sind meine Codes:

Was s verwirrend am meisten ist, dass mProgressBar und comtHeader zeigen, warum ist die Recyclerview noch Anzeigen der abgerufenen Elemente.
Bitte, können Sie mir sagen, wo ich falsch lag?
Danke, das hat es in Ordnung gebracht. Vielen Dank – Abdullq
