Java Kotlin RecyclerView，底片内有多个视窗夹
我在尝试显示包含多个ViewHolder的回收器时遇到问题，我正在测试并发送一个仅包含数据的自定义列表，以显示第一个ViewType的列表 付款.添加（购买（0，R.drawable.ic_购物车，“”，“”） payments.add（购买（0，R.drawable.ic_favorite，“，”） payments.add（购买（0，R.drawable.ic_箭头_back，“，”） 这是最底层的Java Kotlin RecyclerView，底片内有多个视窗夹,java,android,android-fragments,kotlin,android-recyclerview,Java,Android,Android Fragments,Kotlin,Android Recyclerview,我在尝试显示包含多个ViewHolder的回收器时遇到问题，我正在测试并发送一个仅包含数据的自定义列表，以显示第一个ViewType的列表 付款.添加（购买（0，R.drawable.ic_购物车，“”，“”） payments.add（购买（0，R.drawable.ic_favorite，“，”） payments.add（购买（0，R.drawable.ic_箭头_back，“，”） 这是最底层的 class PaymentStepsFragment : SuperBottomSheetF

根据要求，我添加了一个布局，我将其称为RecyclerView

另外，视图持有者的类型似乎没有达到覆盖功能…检查布局XML它看起来RecyclerView
视图被其他视图隐藏了holder可能有问题。itemViewType
在onBindViewHolder
中，是否在onBindViewHolder
中设置了断点检查内部Purchase
如果类型为OK请检查布局如果未设置Match_Parent
heightConstrintLayout
ConstrintLayoutRecyclerView的约束我将使用RecyclerView的布局和值持有者更新问题。ItemViewType在布局中，测试删除最后两个视图，作为问题，谢谢！我要看看如何管理布局来处理其他组件：）
