Ich bin neu in Android, aber ich möchte Navigationsmenü in meiner Anwendung zu machen. Ich erhalte erfolgreich Daten vom Webservice. Aber ich habe ein Problem im Navigationsmenü, wie Web-Service-Menüelement im Navigationsmenü hinzufügen? In dieser Aktivität zuerst Daten über Web-Service abrufen und dann JSON-Objekt in Array-Objekt konvertieren und dann PrintMenuFunktion aufrufen, um Menüelemente in der Navigation hinzufügen Ich habe ein Problem in diesem Abschnitt Ich weiß nicht, wie Sie ein Menü hinzufügen.Navigationsmenü in android

Welchen Fehler erhalten Sie? posten Sie auch Ihr Logbuch. –
Es gibt kein Fehler Problem ist dies ich habe keine Ahnung darüber, wie man Menüelemente dynamicall und wie von einer Aktivität zu einer anderen Aktivität entsprechend Menüelement ID umleiten –
