quand je viens d'utiliser TextView dans la deuxième xml, il a bien fonctionné mais je dois ajouter une carte Visionner comme un containner à ce TextView? ?

Answer 1

Si vous utilisez un ArrayAdapter et que vous disposez d'une mise en forme modifiée (comme vous l'avez fait), vous devez utiliser le constructeur avec l'ID TextView.

Vous appelez le construtor avec faux arguments, afin de changer toute votre application à ceci:

YourAdapter:

public GooglePlacesAutocompleteAdapter(Context context, int layoutId, int textViewResourceId) { 
     super(context, layout, textViewResourceId); 
     this.context = context; 
    } 

YourActivity:

dataAdapter = new GooglePlacesAutocompleteAdapter(this, R.layout.adapter_google_places_autocomplete, R.id.textView);
