Android 在一个布局中的适配器之间传递数据

我是kotlin的初学者，我可以在一个布局中传递数据或项目吗

这是第一个适配器代码

    }

            data: DataX?,
            kasirInterface : KasirInterface
        ) {

                    if (counterItem >= data.stock) return@setOnClickListener
                    counterItem++
                    kasirInterface.addItem(data)
