Ich habe die beiden Spinner in xml erstellt, nämlich myspinner und myspinner1. Der myspinner-Wert wird aus dem json-Wert bezogen. Basierend auf dem ausgewählten myspinner-Element erhalten wir die Hotel-ID. Die abgerufene Hotel-ID wird verwendet, um die andere AsyncT1 aufzurufen. In der AsyncT1 wird der myspinner1-Wert aufgelistet. Mein Problem ist, wenn ich wählen sie den Myspinner der myspinner1 Wert nicht aktualisiert wird, bleibt same.I die adapter.notifydatasetchanged versucht haben(), aber bis jetzt nichtAktualisiere den zweiten Spinner basierend auf dem ersten Spinner Item

Schreiben Sie mySpinner.setOnItemSelectedListener stattdessen in MainActivity. –
danke für ur answer, aber es funktioniert nicht – sri
