Création d'un niveau de classe statique interne supérieur

Question

Im implémentation de l'analyse des résultats des directions de google dans les classes de modèles Java.

HttpRequest request = requestFactory.buildGetRequest(url); 
HttpResponse httpResponse = request.execute(); 
DirectionsResult directionsResult=httpResponse.parseAs(DirectionsResult.class); 

... 

public static class DirectionsResult { 
    @Key 
    public List<Route> routes; 
} 

public static class Route { 
    @Key 
    public List<Leg> legs; 
} 

public static class Leg { 
    @Key 
    public Distance distance; 

    @Key 
    public Duration duration; 

} 

public static class Distance 
{ 
    @Key 
    public String text; 
} 

public static class Duration 
{ 
    @Key 
    public String text; 
} 


    ... 

Pour acess les données que je peux ensuite utiliser:

Log.d(TAG,"directions result distance text: "+directionsResult.routes.get(0).legs.get(0).distance.text); 

Ma question est de savoir comment créer la classe de niveau supérieur séparé appelé DirectionsResult et acess ses variables membres?

J'ai essayé mimer le comportement de la classe statique de classe supérieure, mais sans succés, a été d'obtenir l'erreur ...

Answer 1

Vous créez un nouveau fichier Java DirectionResults.java. Vous copiez la classe exactement telle quelle, en supprimant le mot-clé static de la ligne qui déclare la classe. Ajoutez la ligne de paquet normale et toutes les importations nécessaires. C'est tout ce que vous devriez faire.

public class DirectionsResult { 
    @Key 
    public List<Route> routes; 
}
