我应该如何使用改造获取数组下的图像 [英] How should I fetch images under an array using retrofit
问题描述
我在数组下有图像...这是我的 json:
I have images under array...here is my 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"
}
]
}
}
从上面的json你会看到product_images
数组下有两张图片
我会告诉你 product_images
下的图片不是固定的......它可能是不同的 id..可以包含 3 或 2 或 1 或 4
From the above json you'll see there are two images under product_images
array
I will tell you images under product_images
are not fixed ...it could be differnt ids..can be contain 3 or 2 or 1 or 4
这是我的第二个 json 响应,其中 3 个图像的 id 3 id 在数组下检索-->
Here is my second json response where id 3 ids with 3 images are retrive under array-->
{
"status": 200,
"data": {
"id": 5,
"product_category_id": 2,
"name": "HP Fabric Office Chair",
"producer": "HP",
"description": "Serene Staff Chair
Five Star Nylon Base with Nylon Castor
Free 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中,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 个图像视图中加载这些图像,还要注意图像不是固定的,因为您可以看到 json 1 和 json 2.
预先感谢您的帮助.
推荐答案
试试这个方法...
首先从您的响应中创建模型类,为此复制您的响应并在此处添加您的响应 http://pojo.sodhanalibrary.com/ ,在这里它将根据您的响应创建所有 pojo 类.
First off create model classes from your response, for that copy your response and add your response here http://pojo.sodhanalibrary.com/ , here it will create all pojo classes from your response.
现在...改变你的api调用方法
Now... change you api call method
Call<Product_base_response>
到
Call<JsonObject>
现在只需在 onResponse 方法中打印响应
Now just print response in onResponse method like
Log.d("===","onResponse :: "+response.body());
如果您在此处收到回复,
if you got your response here,
Gson gson = new Gson();
Your_Main_Model mainModel = gson.fromJson(jsonObject.toString(), Your_Main_Model.class);
现在,要获得图像,您需要通过像
Now, to get images you need to go through main model like
Main_model.data_object_model.product_images_model_list.get(0).getImage();
希望这有效,如果你没有得到它或这不起作用让我知道
Hope this works, if you didn't get it or this not work let me know
