Question

通过改型我可以收到很好的答复，并且我可以在视图上显示模型属性，除了一张图像列表。尽管看到日志包含必需的JSON数据，但我从中获得了空值。由于它是图像列表，因此我正在使用Glide进行显示，并且在日志中显示W/Glide: Load failed for null with size [0x0] class com.bumptech.glide.load.engine.GlideException: Received null model

我要访问的属性是promotionalimages类中的Data。

如果需要更多信息，请告诉我。

我在做什么错？

型号：

RestaurantModel

我的活动的一部分，我在其中显示响应：

Call<RestaurantModel> call = apiInterface.getRestaurant(getSharedPreference.getToken(), identifier);
    call.enqueue(new Callback<RestaurantModel>() {
        @Override
        public void onResponse(@NonNull Call<RestaurantModel> call, @NonNull Response<RestaurantModel> response) {
            restaurant = response.body();

            rName.setText(restaurant.getData().getName());
            ratingtxt.setText(String.format("%s", restaurant.getData().getAvgRatingCount()));
            Glide.with(context).load(restaurant.getData().getPromotionalimages().get(0).getPromotionalPicture()).apply(RequestOptions.centerCropTransform().placeholder(R.drawable.default_image)).into(holder.image);

响应：

Answer 1

在JSON响应中，我看到：

"promotionalimages": [
    {
        ...
        "promotional_picture": "https://x.co/storage/promotionalimages/0464eee2-5160-40e7-8ae0-77e7484fe251/15b5f1ec13a9b7.png",
    }
]

但是，在您的模型类中，我看到了：

public static class Promotionalimage {
    ...
    private String promotionalPicture;
}

这两个名称不相同：JSON使用promotional_picture，而Java使用promotionalPicture。可能您还设置了一些其他代码，以将下划线转换为驼峰大小写，但我敢打赌，您不会。

有两种修复方法。我建议添加@SerializedName批注：

public static class Promotionalimage {
    ...
    @SerializedName("promotional_picture")
    private String promotionalPicture;
}

但是您也可以简单地更改Java字段的名称：

public static class Promotionalimage {
    ...
    private String promotional_picture;
}

只需尝试毕加索

Picasso.with(context)
                    .load(link)
                    .into(yourView)

好的改装响应中的图像为空模型
