在这里，我只想从上面的response.How获取预览URL，我可以为same.Someone制作POJO类，请帮助我，任何帮助都将不胜感激。

Answer 1

您可以使用此网站生成pojo类。这是链接http://www.jsonschema2pojo.org/

Answer 2

做以下事情：

public class Pixabay{
   public int total;
   public int totalHits;
   public List<Hits> hits;

  // inner class Hits with all attributes 
   public class Hits{
    public int id;
    //..... and so on

     }
  }

我希望你能拍到照片？你必须通过检查它们的值来正确地映射它们。

干杯!

Answer 3

你的课就像

data class pixBit(val hints:List<pixBitList>)
data class pixBitList(val previewURL:String)

将您的响应映射到第一个pojo类，通过访问映射数据中的提示列表，您可以获取每个previewUrl
