Obtenir des données nulles sur le corps de la réponse à l'aide de retrofit2?

Je suis nouveau dans la mise à niveau 2 et j'essaie d'obtenir des données de tableau json mais en obtenant null, c'est l'URL pour obtenir les données.

Mais le plus drôle, c'est quand j'essaye de déboguer dans onResponse Je reçois un message de réussite ainsi que des données response.body . Quel est le problème ici?

https://xenzet.com/GameCheat/viewgamesjson .php

ceci est des données json

class GameRecyclerViewAdapter extends RecyclerView.Adapter<GameRecyclerViewAdapter.ViewHolder> {

    private List<Games> mGames;
    private LayoutInflater mInflater;
    private ItemClickListener mClickListener;

    // data is passed into the constructor
    GameRecyclerViewAdapter(Context context, List<Games> games) {
        this.mInflater = LayoutInflater.from(context);
        this.mGames = games;
    }

    // inflates the row layout from xml when needed
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = mInflater.inflate(R.layout.gameitem, parent, false);
        return new ViewHolder(view);
    }



    // binds the data to the TextView in each row
    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        Games Game = mGames.get(position);
        String Gameid = Game.getGameid();
        String Gameicon = Game.getGameIcon();
        String Gamename = Game.getGamesName();
        holder.GameNameTxt.setText(Gamename);
        Glide.with(holder.GameIconImage.getContext()).load(Game.getGameIcon()).thumbnail(0.1f).
                placeholder(R.color.colorPrimary).diskCacheStrategy(DiskCacheStrategy.NONE).into(holder.GameIconImage);

    }

    // total number of rows
    @Override
    public int getItemCount() {


        return mGames == null ? 0 : mGames.size();

    }


    // stores and recycles views as they are scrolled off screen
    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        TextView GameNameTxt;
        ImageView GameIconImage;
        ViewHolder(View itemView) {
            super(itemView);
            GameNameTxt = itemView.findViewById(R.id.gamename);
            GameIconImage = itemView.findViewById(R.id.imageView);
            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
            if (mClickListener != null) mClickListener.onItemClick(view, getAdapterPosition());
        }
    }


    // allows clicks events to be caught
    void setClickListener(ItemClickListener itemClickListener) {
        this.mClickListener = itemClickListener;
    }

    // parent activity will implement this method to respond to click events
    public interface ItemClickListener {
        void onItemClick(View view, int position);

    }
}

c'est la méthode qui essaie d'obtenir des données

public class Games {

    @SerializedName("gameid")
    @Expose
    private String gameid;
    @SerializedName("gameIcon")
    @Expose
    private String gameIcon;
    @SerializedName("Games_Name")
    @Expose
    private String gamesName;

    public String getGameid() {
        return gameid;
    }

    public void setGameid(String gameid) {
        this.gameid = gameid;
    }

    public String getGameIcon() {
        return gameIcon;
    }

    public void setGameIcon(String gameIcon) {
        this.gameIcon = gameIcon;
    }

    public String getGamesName() {
        return gamesName;
    }

    public void setGamesName(String gamesName) {
        this.gamesName = gamesName;
    }

//    public Games(String Gameid,String Gameicon,String GameName)
//    {
//      this.gameid = Gameid;
//      this.gameIcon = Gameicon;
//      this.gamesName = GameName;
//
//    }

}

ceci est ApiClient

et Api

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_games);
    gameslist = new ArrayList<Games>();
    RecyclerView recyclerView = findViewById(R.id.recyclerview_gameslist);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));
     fetch_information();

    Toast.makeText(getApplicationContext(),"" +gamescounter, Toast.LENGTH_SHORT).show();

    adapter = new GameRecyclerViewAdapter(this, gameslist);

   recyclerView.setAdapter(adapter);
    adapter.setClickListener((GameRecyclerViewAdapter.ItemClickListener) this);
}

et dans OnCreate, j'appelle chercher des informations méthode.

public interface Api {

    @GET("viewgamesjson.php")
    Call<List<Games>> GetGames();
}

tente de remplir les données de la liste des jeux dans la vue du recycleur mais échoue car elle est nulle.

c'est logcat

public class ApiClient {

    public static  String Base_URL ;

    public static Retrofit retrofit;

    public static Retrofit getApiClient()
    {
        if (retrofit == null)
        {
            Base_URL ="https://xenzet.com/GameCheat/";
            retrofit = new Retrofit.Builder().baseUrl(Base_URL)
                    .addConverterFactory(GsonConverterFactory.create()).build();

        }
        return retrofit;
    }
}

Ceci est des jeux de classe

 public void fetch_information() {

        ApiInterface = ApiClient.getApiClient().create(Api.class);

        Call<List<Games>> call = ApiInterface.GetGames();


        call.enqueue(new Callback<List<Games>>() {
            @Override
            public void onResponse(Call<List<Games>> call, Response<List<Games>> response) {
                if(response.isSuccessful()) {

                    gameslist = response.body();
                    gamescounter = gameslist.size();
                    adapter = new GameRecyclerViewAdapter(GamesActivity.this, gameslist);
                    recyclerView.setAdapter(adapter);
                }
            }


            @Override
            public void onFailure(Call<List<Games>> call, Throwable t) {
                Toast.makeText(getApplicationContext(), t.getMessage(), Toast.LENGTH_SHORT).show();
            }
        });

    }
