在這里，我只想從上面的響應中獲取預覽 URL。我怎樣才能制作 POJO class 。有人請幫助我，任何幫助將不勝感激。

Answer 1

你可以使用這個網站來生成 pojo 類。 這是鏈接http://www.jsonschema2pojo.org/

Answer 2

執行以下操作：

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

     }
  }

我希望你得到圖片？ 你必須通過檢查它們的值來正確地 map 它們。

干杯!

Answer 3

你的 class 會像

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

Map 您對第一個 pojo class 的響應，通過從映射數據訪問提示列表，您可以獲取每個 previewUrl
