Question

我在演示项目中使用改装库进行调用。

我收到以下错误：

java.lang.NumberFormatException：预期为int但在第1行第8454行为0.6。$ .result.results.ads [2] .acres

我认为这归功于GSON。

我会告诉你它被抓住的JSON：

       "property_type":"site",
       "house_type":"",

    },

我没有经验丰富的Retrofit所以决定学习和整合这个项目。

有人会有什么建议吗？

我无法控制发送的JSON。

Answer 1

尝试使用float或double代替int; 0.6不是整数，它是小数。请注意，java会自动将小数解释为doubles;浮点的一个例子是0.6f。

Answer 2

那是因为解析器期待int，而它获得的实际值是float。您可以做的是，在模型中将该值的类型从int更改为float。

这可能会在您使用该值的任何地方导致代码出现问题。您可以通过将浮点值转换为整数来解决它。
