如何為此JSON創建模型？

Question

在下面的json ，有兩個產品對象，產品有時會不斷變化，有100多個產品（我嘗試了json到pojo轉換器，但在主類中有兩個產品有兩個）...這些產品是動態的..我正在使用改造

Answer 1

有兩種方法：

第一種方法是使用Gson

請看一下這個庫（Gson） 。

您可以在該平台上找到有關如何使用Gson的數千個問題

---

第二種方法是使用Android默認庫

您僅具有產品對象列表，因此在使用此庫可以迭代此數組內的每個JSONObject並將其轉換為模型之后，需要使用JSONArray 。

既然很容易，我就不會發布完整的對象。 只需創建一個包含對象中所有值的類，然后了解這些選項。

要么

這是解決方案。
