Es tut mir leid, den ganzen Code zu veröffentlichen, um Verwirrung durch andere zu vermeiden.Ich habe GoogleMap erfolgreich in meine Anwendung implementiert und ich erhalte auch meinen aktuellen Standort.Meine Anforderung ist, die Adresse des Standorts zu erhalten Wo auch immer der Marker platziert wird. Der Marker ist ziehbar, aber wenn ich den Marker verschiebe oder ziehe, bekomme ich nichts, nicht einmal das Log. Ich habe ungefähr 2 Tage nach Lösung gesucht. Bitte versuchen Sie mir zu helfen. Hier ist meine Aktivität. Ich stelle den ganzen Code einschließlich der Importe zu Ihrem besseren Verständnis zur Verfügung.GoogleMap.OnMarkerDragListener funktioniert nicht richtig
