我应该如何使用改造在阵列下获取图像

Question

我有数组下的图像...这是我的json：

{
    "status": 200,
    "data": {
        "id": 1,
        "product_category_id": 1,
        "name": "Centre Coffee Table",
        "producer": "Luna",
        "description": "Mild Steel Base In Poder Coated White Finish.8 mm Tempered Glass Table Top.Bottom Shelf In Paimted Brown Glass.",
        "cost": 5000,
        "rating": 3,
        "view_count": 21243,
        "created": "2015-09-07T09:24:05+0000",
        "modified": "2020-07-27T10:52:42+0000",
        "product_images": [
            {
                "id": 1,
                "product_id": 1,
                "image": "http://staging.php-dev.in:8844/trainingapp/uploads/prod_img/thumb/medium/9dc6234da018916e545011fa1.jpeg",
                "created": "2015-09-07T09:40:00+0000",
                "modified": "2015-09-07T09:40:00+0000"
            },
            {
                "id": 6,
                "product_id": 1,
                "image": "http://staging.php-dev.in:8844/trainingapp/uploads/prod_img/thumb/medium/1bfdac02ced672dd1e8e8976c.jpeg",
                "created": "2015-09-07T09:44:11+0000",
                "modified": "2015-09-07T09:44:11+0000"
            }
        ]
    }
}

我会告诉你product_images下的图像是不固定的...它可能是不同的id...可以包含3或2或1或4

这是我的第二个json响应，其中包含3张图片的id 3在数组下被检索

{
    "status": 200,
    "data": {
        "id": 5,
        "product_category_id": 2,
        "name": "HP Fabric Office Chair",
        "producer": "HP",
        "description": "Serene Staff Chair\r\nFive Star Nylon Base with Nylon Castor\r\nFree Delivery",
        "cost": 2222,
        "rating": 3,
        "view_count": 2335,
        "created": "2015-09-07T09:48:51+0000",
        "modified": "2020-07-27T11:50:51+0000",
        "product_images": [
            {
                "id": 10,
                "product_id": 5,
                "image": "http://staging.php-dev.in:8844/trainingapp/uploads/prod_img/thumb/medium/fddd92b395be88ce117936b9f.jpeg",
                "created": "2015-09-07T09:49:33+0000",
                "modified": "2015-09-07T09:49:33+0000"
            },
            {
                "id": 11,
                "product_id": 5,
                "image": "http://staging.php-dev.in:8844/trainingapp/uploads/prod_img/thumb/medium/78b1d4e168280fe5f9cfdff60.jpeg",
                "created": "2015-09-07T09:49:51+0000",
                "modified": "2015-09-07T09:49:51+0000"
            },
            {
                "id": 12,
                "product_id": 5,
                "image": "http://staging.php-dev.in:8844/trainingapp/uploads/prod_img/thumb/medium/b6480396b91bb9e99e40e4ba7.jpeg",
                "created": "2015-09-07T09:50:10+0000",
                "modified": "2015-09-07T09:50:10+0000"
            }
        ]
    }
}

这是我的改造活动：

RetrofitClient.instancetable.fetchUserdetail(id)
        .enqueue(object : Callback<Product_base_response> {
            override fun onFailure(call: Call<Product_base_response>, t: Throwable) {
                Log.d("res", "" + t)

            }

            override fun onResponse(
                call: Call<Product_base_response>,
                response: Response<Product_base_response>
            ) {
                var res = response

             val ret: Product_Data_response? =res.body()?.data
                val retro: List<Product_images_response> = res.body()?.data?.product_images!!

                Log.e("checkdata",ret?.name.toString())
                val ygd=ret?.name.toString()
                text.setText(ygd)
                text2.setText(ret?.producer.toString())
           //need help in here -->>>> 
               Glide.with(getApplicationContext()).load(res?.body()!!.data.product_images.get(0).image).into(imagemain);
                for ( i in res?.body()!!.data.product_images.indices.toString()){//crashes if contain image under get(1)
                     Glide.with(getApplicationContext()).load(res?.body()!!.data.product_images.get(1).image).into(imagemain1);


                }
               Glide.with(getApplicationContext()).load(res?.body()!!.data.product_images.get(2).image).into(imagemain2);
               Glide.with(getApplicationContext()).load(res?.body()!!.data.product_images.get(3).image).into(imagemain3);

            }
        })
}

从上面的改造响应代码，当它没有检测到图像数组中的get（1）时，它会崩溃

注意：我必须在4个ImageView中加载这些图像，并且注意图像不是固定的，正如json 1和json 2所示。

提前感谢帮助。

Answer 1

试试这种方法...

首先从你的回答中创建模型类，复制你的回答并在这里添加你的回答http://pojo.sodhanalibrary.com/，这里它将从你的回答中创建所有的pojo类。

现在…更改api调用方法

Call<Product_base_response>

自

Call<JsonObject>

现在只需在 onResponse 方法中打印响应，如

Log.d("===","onResponse :: "+response.body());

如果你在这里得到了回应，

   Gson gson = new Gson();
Your_Main_Model mainModel = gson.fromJson(jsonObject.toString(), Your_Main_Model.class);

现在，要获取图像，您需要通过主模型，例如

Main_model.data_object_model.product_images_model_list.get(0).getImage();

希望这工作，如果你没有得到它或这不工作让我知道
