Gson仅复制json数组的前3个元素

Question

我在json解析中遇到问题。我正在使用凌空来获取数据，并使用gson将数据放入Java对象中。我的代码没有任何错误， 但是我通过凌空接收所有数据，但是gson从json数据中仅复制了数组中的3个元素。

这是获取数据的代码

这是对象

 public void get_Standing_data(final Context context,String league){

    final Workdone workdone= (Workdone) context;
    final String Url = "http://api.football-data.org/v2/competitions/"+league+"/standings";
    final RequestQueue queue = Volley.newRequestQueue(context);
    final StringRequest request = new StringRequest(Url, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            CompetitionStanding data=null;
            Log.d("fetched data", "onResponse: " + response);
            GsonBuilder gsonBuilder = new GsonBuilder();
            Gson gson = gsonBuilder.create();
            data = gson.fromJson(response, CompetitionStanding.class);
            workdone.standing_done(data);
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            workdone.standing_notdone();
            //  Toast.makeText(context, "something went wrong", Toast.LENGTH_SHORT).show();
        }
    }){
        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            Map<String, String>  params = new HashMap<>();
            params.put("X-Auth-Token", key);
            params.put("Accept", "application/json");
            return params;
        }
    };


    queue.add(request);


}

这是api的响应

 public class CompetitionStanding {

    @SerializedName("filters")
    @Expose
    private Filters filters;
    @SerializedName("competition")
    @Expose
    private Competition competition;
    @SerializedName("season")
    @Expose
    private Season season;
    @SerializedName("standings")
    @Expose
    private List<Standing> standings = null;

    public Filters getFilters() {
        return filters;
    }

    public void setFilters(Filters filters) {
        this.filters = filters;
    }

    public Competition getCompetition() {
        return competition;
    }

    public void setCompetition(Competition competition) {
        this.competition = competition;
    }

    public Season getSeason() {
        return season;
    }

    public void setSeason(Season season) {
        this.season = season;
    }

    public List<Standing> getStandings() {
        return standings;
    }

    public void setStandings(List<Standing> standings) {
        this.standings = standings;
    }

}

，但是仅从此json复制3个元素 我做错什么了吗？ 任何帮助将不胜感激
