我从以下改装服务中获得了一个json结果：

{
    "result": {
        "totalCount": 15,

        "offset": 0,

我在改装后变得像bellow一样：

RetrofitApi.getVendorAdminApi()
        .getAdminProductss(userToken, limit, pageNumber, filters)
        .enqueue(new Callback<List<ProductsModel>>() {
            @Override
            public void onResponse(Call<List<ProductsModel>> call, Response<List<ProductsModel>> response) {
                if (response.isSuccessful()) {
                    resultListener.onSuccess(response.body());
                } else {
                    resultListener.onFailure();
                }
            }

            @Override
            public void onFailure(Call<List<ProductsModel>> call, Throwable t) {
                resultListener.onFailure();
                t.printStackTrace();
            }
        });

但是告诉我：

Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $

下面是我的模型：

public class ProductsModel {

    @SerializedName("result")
    @Expose
    private ResultProducts result;

    public ResultProducts getResult() {
        return result;
    }

    public void setResult(ResultProducts result) {
        this.result = result;
    }

}

json数据中的“result”节点是一个对象而不是数组。json的模型类如下

并且回调将是回调

您可以通过响应获得产品结果。正文（）。getResult（）。getProducts（）；

我已根据http://pojo.sodhanalibrary.com/.如果需要，您可以参考我给出的模型创建另一个。

将改装呼叫更改为：

RetrofitApi.getVendorAdminApi()
        .getAdminProductss(userToken, limit, pageNumber, filters)
        .enqueue(new Callback<ProductsModel>() {
            @Override

                    resultListener.onFailure();

您的问题是预期BEGIN_ARRAY但BEGIN_OBJECT在第1行第2列路径$

所以改变列表

>

如果JSON是JSONArray，您可以将其解析为List（如List

如果JSON是JSONObject，您可以将其解析为Object（如ProductsModel）。

更改为此。

@Override
public void onResponse(Call<ProductsModel> call, Response<ProductsModel> response) {
    if (response.isSuccessful()) {
        resultListener.onSuccess(response.body());
    } else {
        resultListener.onFailure();
    }
}

而且

Call<ProductsModel> getAdminProductss();
