如何使用卡片创建水平滚动的 RecyclerView
Howto create horizontal scrolling RecyclerView with Cards
尝试设置一个水平滚动的 RecyclerView,它接受 CardView 并在屏幕上水平滚动它们。我试图通过创建一个 LinearLayout 并将 RecyclerView 方向设置为水平并将滚动条设置为水平来设置它。不幸的是,这不起作用,我仍然看到卡片填满整个垂直 space 并垂直滚动。不确定为什么会发生这种情况或如何解决它。

您应该以编程方式设置 LayoutManager
recyclerView.layoutManager = LinearLayoutManager(context, RecyclerView.HORIZONTAL, false )
要进行水平滚动,需要以编程方式将水平布局管理器设置为您的回收视图,如下所示。
recyclerView.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.HORIZONTAL, false));
recyclerView.setAdapter(yourAdapter);
