次の構造の JSON があります。

{
    "items":[
        {
            "product":{
                "product_id":"some",
                "price_id":"some",
                "price":"some",
                "title_fa":"some",
                "title_en":"Huawei Ascend Y300",
                "img":"some",
                "has_discount_from_price":"0",
                "discount_from_price":null,
                "type_discount_from_price":null,
                "has_discount_from_product":"0",
                "discount_from_product":null,
                "type_discount_from_product":null,
                "has_discount_from_category":"0",
                "discount_from_category":null,
                "type_discount_from_category":null,
                "has_discount_from_brand":"0",
                "discount_from_brand":null,
                "type_discount_from_brand":null,
                "weight":null,
                "features":[
                    {
                        "feature_value":"#000000",
                        "feature_id":"some",
                        "feature_title":"some"
                    },
                    {
                        "feature_value":"some",
                        "feature_id":"1652",
                        "feature_title":"some"
                    }
                ]
            },
            "number":1,
            "feature_id":"56491,56493",
            "price_inf":{
                "has_discount":0,
                "discount_type":0,
                "final_price":"400000",
                "value_discount":0
            },
            "cart_id":13
        }
    ]
}

次のJavaコードを使用して、要素「product_id」および「price_id」にアクセスしようとしています:

try{
        JSONArray feedArray=response.getJSONArray("items");
        for (int i=0;i<feedArray.length();i++){
            JSONObject feedObj=feedArray.getJSONObject(i);

            JSONObject pro=feedObj.getJSONObject("product");
            Product product = new Product();
            product.setPrice(pro.getDouble("price_id"));
            product.setTitle_fa(pro.getString("price_id"));}}

しかし、製品が見つからないというエラーが表示されます。パーサーの何が問題なのですか?

Validate and create Pojo for your json here

use 

Data data = gson.fromJson(this.json, Data.class);

follow https://stackoverflow.com/a/5314988/5202007

By the way your JSON is invalid .
