如何使用GSON和Volley Android在2个Modal类中获取json数据

我有2个类似结果的模态类，另一个是学生我希望使用gson在两个模态类中获取所有json响应我尝试这样* json响应： - {“”成功“：”1“，”请求“：”/ API / V1 / getmarketsummaries “ ”消息“： ”“， ”结果“：[{ ”MarketID“： ”18“， ”LastPrice“： ”0.01458900“， ”改变“： ” - 1.10“， ”HighPrice“：” 0.01497193" ， “LowPrice”： “0.01453000”， “音量”： “5.27365150”， “BTCVolume”： “5.27365150”， “TradeCount”： “344”， “BidPrice”： “0.01458012”， “AskPrice”： “0.01470990” “BuyOrderCount”： “228”， “SellOrderCount”： “864”}，{ “MarketID”： “43”， “LastPrice”： “0.00004443”， “改变”： “0.00”， “HighPrice”： “0.00000000” “LowPrice”： “0.00000000”， “卷”： “0.00000000”， “BTCVolume”： “0.00000000”， “TradeCount”： “0”， “BidPrice”： “0.00003363”， “AskPrice”： “0.00004433”，” BuyOrderCount“：”29“，”SellOrderCount“：”432“}}} *

如何使用 Gson 在模态类中设置所有响应

Gson gson = new Gson();

Gson gson = new Gson（）;

结果result = gson.fromJson（response，Result.class）;

但是无法获得那些数据，我怎样才能实现......

public class Result {

    @SerializedName("MarketID")
    @Expose
    private String marketID;
    @SerializedName("LastPrice")
    @Expose
    private String lastPrice;
    @SerializedName("Change")
    @Expose
    private String change;
    @SerializedName("HighPrice")
    @Expose
    private String highPrice;
    @SerializedName("LowPrice")
    @Expose
    private String lowPrice;
    @SerializedName("Volume")
    @Expose
    private String volume;
    @SerializedName("BTCVolume")
    @Expose
    private String bTCVolume;
    @SerializedName("TradeCount")
    @Expose
    private String tradeCount;
    @SerializedName("BidPrice")
    @Expose
    private String bidPrice;
    @SerializedName("AskPrice")
    @Expose
    private String askPrice;
    @SerializedName("BuyOrderCount")
    @Expose
    private String buyOrderCount;
    @SerializedName("SellOrderCount")
    @Expose
    private String sellOrderCount;

    public String getMarketID() {
        return marketID;
    }

    public void setMarketID(String marketID) {
        this.marketID = marketID;
    }

    public String getLastPrice() {
        return lastPrice;
    }

    public void setLastPrice(String lastPrice) {
        this.lastPrice = lastPrice;
    }

    public String getChange() {
        return change;
    }

    public void setChange(String change) {
        this.change = change;
    }

    public String getHighPrice() {
        return highPrice;
    }

    public void setHighPrice(String highPrice) {
        this.highPrice = highPrice;
    }

    public String getLowPrice() {
        return lowPrice;
    }

    public void setLowPrice(String lowPrice) {
        this.lowPrice = lowPrice;
    }

    public String getVolume() {
        return volume;
    }

    public void setVolume(String volume) {
        this.volume = volume;
    }

    public String getBTCVolume() {
        return bTCVolume;
    }

    public void setBTCVolume(String bTCVolume) {
        this.bTCVolume = bTCVolume;
    }

    public String getTradeCount() {
        return tradeCount;
    }

    public void setTradeCount(String tradeCount) {
        this.tradeCount = tradeCount;
    }

    public String getBidPrice() {
        return bidPrice;
    }

    public void setBidPrice(String bidPrice) {
        this.bidPrice = bidPrice;
    }

    public String getAskPrice() {
        return askPrice;
    }

    public void setAskPrice(String askPrice) {
        this.askPrice = askPrice;
    }

    public String getBuyOrderCount() {
        return buyOrderCount;
    }

    public void setBuyOrderCount(String buyOrderCount) {
        this.buyOrderCount = buyOrderCount;
    }

    public String getSellOrderCount() {
        return sellOrderCount;
    }

    public void setSellOrderCount(String sellOrderCount) {
        this.sellOrderCount = sellOrderCount;
    }

}

public class Market {

    @SerializedName("success")
    @Expose
    private String success;
    @SerializedName("request")
    @Expose
    private String request;
    @SerializedName("message")
    @Expose
    private String message;
    @SerializedName("result")
    @Expose
    private List<Result> result = null;

    public String getSuccess() {
        return success;
    }

    public void setSuccess(String success) {
        this.success = success;
    }

    public String getRequest() {
        return request;
    }

    public void setRequest(String request) {
        this.request = request;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public List<Result> getResult() {
        return result;
    }

    public void setResult(List<Result> result) {
        this.result = result;
    }

}
