我想将水平RecyclerView（ InnerRecyclerView ）放在另一个垂直RecyclerView（ OuterRecyclerView ）中，并在两次单独的凌空调用之后将数据解析到其中。在第一个Web服务调用之后，我能够成功地将数据解析到垂直RecyclerView中。现在，我试图将第二个Web服务中的数据放入水平RecyclerView中。
为此，我实现了两个单独的RecyclerView适配器类。我不明白的是如何像在第一个Web服务调用中那样传递第二个Web服务调用中的数据，从而在OuterRecyclerView中定义InnerRecyclerView并使整个事情协同工作。我是一个初学者，感谢您的帮助。
