JSON中的Android Volley数组

Question

我有这种JSON响应

{"error":false,"country":"United Kingdom","country_id":"903",
"currency":"GBP","product_list":["5","10","15","20","25","30","40","50"]}

并且我能够解析国家，国家/地区和货币，没有问题，当我尝试解析产品列表时，问题就从产品列表开始！代码下方

                try {
                    boolean error = response.getBoolean("error");
                if (!error){ 
                    String country = response.getString("country");
                    int country_id = response.getInt("country_id");
                    String currency = response.getString("currency");
                    List<Tarif> tarifs = new 
                    Gson().fromJson(response.getJSONArray("product_list").toString(), new 
                    TypeToken<List<Tarif>>(){}.getType());
                    new DtoneTarifs(country, country_id, currency, tarifs);
                 }
            }

这是我的Tarif和其他班级

public class  Tarifs {
public String country;
public int country_id;
public String currency;
public List<Tarif> tarifList;

public Tarifs (String country, int country_id, String currency, List<Tarif> tarif){
    this.country = country;
    this.country_id = country_id;
    this.currency = currency;
    this.tarifList = tarif;
}
}

我想在Tarif类中填写product_list，其中只有一个参数接受并在recycler_view中显示它们

{"error":false,"country":"United Kingdom","country_id":"903",
"currency":"GBP","product_list":["5","10","15","20","25","30","40","50"]}

您可以看到product_list是字符串值的JSON数组。但是您正在将其转换为Tarif类型的列表。应该将其转换为字符串类型列表。

将Tarif的值设置为JSON Array的自定义对象，或将列表类型更改为字符串。

应该是这样：

try {
      boolean error = response.getBoolean("error");
      if (!error){ 
         String country = response.getString("country");
         int country_id = response.getInt("country_id");
         String currency = response.getString("currency");
         List<String> tarifs = new 
         Gson().fromJson(response.getJSONArray("product_list").toString(), new 
                    TypeToken<List<String>>(){}.getType());
         Tarifs result = new Tarifs(country, country_id, currency, tarifs);
       }
 }

关税课

public class  Tarifs {
public String country;
public int country_id;
public String currency;
public List<String> tarifList;

public Tarifs (String country, int country_id, String currency, List<String> tarif){
    this.country = country;
    this.country_id = country_id;
    this.currency = currency;
    this.tarifList = tarif;
}
}
