AutoCompleteTextView avec Google Endroits indiqués dans la ListView comme Uber

Ici est un exemple de la façon de le faire.

Vous avez le bonus de récupérer les AutocompletePrediction de la carte. Appelez simplement getItem(int position) de la AutoCompleteTextView's AdapterView.OnItemClickListener par exemple et utiliser des données à partir de la prédiction cliqué comme vous le souhaitez.
