retrofit2 嵌入式列表在有效响应时返回 null

Question

我有一个 json request/response 对，我想在 android 中使用 retrofit2。请求工作正常，我得到了此处显示的响应，我通过向项目添加日志记录对其进行了验证。

前两个字段返回到我的回调正常，但 "result" 数组始终为空。

发送：

{"jsonrpc": "2.0", "method": "Player.GetActivePlayers", "id": 1}

回来：

{"id":1,"jsonrpc":"2.0","result":[{"playerid":0,"playertype":"internal","type":"audio"}]}

我使用网站 jsonschema2pojo 生成了以下 POJO 类

package retroKodi;

import java.util.List;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

public class player_GetActivePlayersReturn_root {

    @SerializedName("id")
    @Expose
    private int id;
    @SerializedName("jsonrpc")
    @Expose
    private String jsonrpc;
    @SerializedName("playerGetActivePlayersResult")
    @Expose
    private List<player_GetActivePlayersReturn_Result> playerGetActivePlayersResult = null;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getJsonrpc() {
        return jsonrpc;
    }

    public void setJsonrpc(String jsonrpc) {
        this.jsonrpc = jsonrpc;
    }

    public List<player_GetActivePlayersReturn_Result> getPlayerGetActivePlayersResult() {
        return playerGetActivePlayersResult;
    }

    public void setPlayerGetActivePlayersResult(List<player_GetActivePlayersReturn_Result> playerGetActivePlayersResult) {
        this.playerGetActivePlayersResult = playerGetActivePlayersResult;
    }

}

子列表

package retroKodi;

import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

public class player_GetActivePlayersReturn_Result {

    @SerializedName("playerid")
    @Expose
    private int playerid;
    @SerializedName("playertype")
    @Expose
    private String playertype;
    @SerializedName("type")
    @Expose
    private String type;

    public int getPlayerid() {
        return playerid;
    }

    public void setPlayerid(int playerid) {
        this.playerid = playerid;
    }

    public String getPlayertype() {
        return playertype;
    }

    public void setPlayertype(String playertype) {
        this.playertype = playertype;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

}

Activity 通话

kodiRequest_nullParams thisRequest = new kodiRequest_nullParams("2.0", "Player.GetActivePlayers", 15);
        (ApiUtilKodi.sendPost().kodiPlayer_GetActivePlayers(thisRequest)).enqueue(new Callback<player_GetActivePlayersReturn_root>() {
            @Override
            public void onResponse(Call<player_GetActivePlayersReturn_root> call, Response<player_GetActivePlayersReturn_root> response) {
                player_GetActivePlayersReturn_root thisResponse = response.body();
                String hi = "hi";
                //List<player_GetActivePlayersReturn_root.playerGetActivePlayersResult> thisResultList = thisResponse.getPlayerGetActivePlayersResult();
            }

            @Override
            public void onFailure(Call<player_GetActivePlayersReturn_root> call, Throwable t) {
                Log.d("response", t.getStackTrace().toString());
            }
        });

在 "thisResponse" 字段中，"playerGetActivePlayersResult" 字段显示为空。

我原以为它会显示一个数组，或者至少是一个指针，然后我可以将其分配给一个列表。

我到底错过了什么？？？？ None 我能找到的示例中有一个列表作为响应的一部分。它们要么都是简单的 1 级 json 模式，要么就是假设了一个简单模式列表。

在classplayer_GetActivePlayersReturn_root变化

@SerializedName("playerGetActivePlayersResult")
@Expose
private List<player_GetActivePlayersReturn_Result> playerGetActivePlayersResult = null;

和

@SerializedName("result")
@Expose
private List<player_GetActivePlayersReturn_Result> result = null;
