Holen Sie sich einen Standort für Kivy Garden MapView

Question

Ich brauche den aktuellen Standort in GPS und passiere für mapview. Mein Code funktioniert nicht, Rückgabe Fehler: Code funktioniert, wenn in kv langue in MapView add lat: und lon: numerischer Wert. Irgendwelche Ideen für die Werte lat und lon von der Funktion on_locations?

ValueError: None is not allowed for MapView.lat

ich hasse wirklich Antworten hier Codierung, folgen diese working code ich einige Variablen in der App-Klasse nur hinzugefügt und die der on_location Funktion und verändert die Werte in der Mapview zu das der Variablen, die in der App-Klasse erstellt wurden. hoffe, es funktioniert
