レトロフィット1.9応答

Question

JSONスキーマnullである：

https://gyazo.com/654b65bc293518d8202573ddccfe1b61

私はresults arrayでfirst objectをアクセスもしたいが、私はretrofit thorughそれを取得しようとしたとき、それはresults配列が空であることを述べています。何故ですか？ （jsonschema2pojoから生成）

インタフェース

public interface MapInterface { 
@GET("/json") 
public void getResults(@Query("location") String location, @Query("radius") double radius, 
          @Query("type") String type, @Query("key") String key, Callback<Result> response); 

} 

MainActivity

RestAdapter restAdapter = new RestAdapter.Builder().setEndpoint("https://maps.googleapis.com/maps/api/place/nearbysearch/json?").build(); 
    MapInterface map = restAdapter.create(MapInterface.class); 

     map.getResults("65.9667,-18.5333", PROXIMITY_RADIUS, "restaurant", placesKey , new Callback<Result>() { 
     @Override 
     public void success(Result result, Response response) { 
      Log.d("Matt", result.getResults().toString()); 
      //this logs `D/Matt: []` 
     } 

     @Override 
     public void failure(RetrofitError error) { 
      Log.d("Matt", error.getMessage()); 
     } 
    });

    public void setReference(String reference) {

    public String getVicinity() {

    public Double getRating() { 
     return rating; 
    } 

    public void setRating(Double rating) { 
     this.rating = rating; 
    } 

} 

Y OUは、GETメソッド

から返されるリターンJavaオブジェクトを追加する必要がありますなぜあなたはあなたのPOJOの検索結果を呼ぶのです。この

public interface MapInterface { 
@GET("/json") 
Call<Result> getResults(@Query("location") String location, @Query("radius") double radius, 
         @Query("type") String type, @Query("key") String key, Callback<Result> response); 

}
