在最后一个数组中，您可以看到车辆数据和附件数据中没有数据并显示括号当 API 返回这种响应时，改造响应将在 onfailure 中代替 onResponse。任何人都可以帮助我吗？这是一个第 3 方 API，我无法修改来自服务器端的响应。

解决方案

在这种情况下，您将返回一个没有属性类型/数据类型的列表，让我清楚如果您有属性/项目，您可以创建一个 pojo 类来捕获响应，那么您如何看待没有模型的响应/pojo 类型的类，所以这是一个导致 OnFailour 方法的异常。如果您想使用此列表，请在此处放置一些属性并将它们设置为空，就像您对其他列表所做的那样

以其他方式，您可以确定在成功响应后是否为空，将此条件放入您的OnResponse方法中

if(response.body().toString().length()==0)
  {
    //array is empty
  }
