java如何在另一个垂直RecyclerView中实现水平RecyclerView

3 月，2 周 Questions & Answers

我想将一个水平的RecyclerView（InnerRecyclerView）放在另一个垂直的RecyclerView（OuterRecyclerView）中，并在两次单独的截取调用后将数据解析到其中。在第一次webservice调用之后，我能够成功地将数据解析到垂直RecyclerView。现在，我试图将第二个Web服务中的数据放入水平RecyclerView

为此，我实现了两个独立的RecyclerView适配器类。我不明白的是如何在OuterRecyclerView中定义InnerRecyclerView，并像在第一个web服务调用中一样通过传递第二个web服务调用的数据使整个过程协同工作。我是这方面的初学者，非常感谢你的帮助
