Comment implémenter une carte glissable comme uber Android, Mise à jour avec changement d'emplacement
Comment implémenter une carte déplaçable comme uber? J'utilise Google Maps v2. En fait, j'ai la solution en référence cet article et je partage ma solution complète ici
Mis à jour avec le dernier code, changement d'emplacement avec autocomplete
Le projet complet peut être trouvé ici
La logique est simple, nous avons besoin d'un framelayout et ajouter une carte et une structure de marqueur à l'intérieur de ce framelayout, puis positionner la gravité de la structure du fabricant sur le centre et obtenir la latitude et la longitude du point central de la carte lors du changement de caméra Voir cette réponse ici est mon code créer activity_maps.xml
