Wir bekommen den Code in Aktivität.Aber nicht in der Lage zu implementieren in Fragment.Hier ist der Code in Aktivität.Bitte helfen Sie uns, den aktuellen Speicherort in Fragment zu finden. Wir sind in der Lage, Marker in Fragmente zu setzen, aber wir sind nicht in der Lage, den aktuellen Ort in Fragment zu bekommen. Bitte helfen Sie uns, wie wir eine Anwendung tun, die sich mit Karten beschäftigt.Karte aktuellen Ort in Fragment

Was ist das Problem? beschreiben in mehr Details mit Code –
wir versuchen, aktuelle Position in Fragment zu bekommen. Wir sind in Aktivität, aber nicht in der Lage zu integrieren in das Fragment – Arya
OK also, was ist das Problem, das Sie in Fragment konfrontiert? –
