java - 如何在另一个类适配器中访问给定适配器的 onBindViewHolder 项？

Question

我想在下一类 ChildViewHolder 的 onBindViewHolder 中访问 DayOfWeek，这样我就可以在 if 语句中使用它，如 ChildRecyclerAdapter 中所示。

class ParentRecyclerAdapter(private var parentArrayList: ArrayList<String>?, private var context: Context, private var mTableFeed: TableFeedJava?
) :  RecyclerView.Adapter<ParentRecyclerAdapter.ParentViewHolder>() {


 override fun onBindViewHolder(holder: ParentViewHolder, position: Int) {
        holder.DayOfWeek.text = this.parentArrayList!![position]
}
 override fun getItemCount(): Int {
        return parentArrayList!!.size
    }

    inner class ParentViewHolder (itemView: View) : RecyclerView.ViewHolder(itemView)

    {
        internal var DayOfWeek: TextView = itemView.findViewById(R.id.dayOfWeek)
        internal var ChildRV: RecyclerView = itemView.findViewById(R.id.ChildRecycler)
}

这是 ChildRecyclerAdapter。我需要 Parent 的 DayOfWeek 才能在此类中使用它作为

class ChildRecyclerAdapter(
    private var time: ArrayList<String>,
    var context: Context,
    private val parentArrayList: ArrayList<String>? = null


) :
override fun onBindViewHolder(holder: ChildViewHolder, position: Int) {

                holder.timeOfDay.text = time[position]
                mTableFeed = TableFeedJava(context,mLectures)
                holder.childofChildRV.adapter = mTableFeed

//THIS IS WHERE I PLAN ON USING THE IMPORTED 'DayOfWeek' AS SEEN ON 'holder.timeOfDay.text'
               for (i in mTimeSpinner!!.indices){
                   if(holder.timeOfDay.text == mTimeSpinner!![i]){
                       holder.childofChildRV.visibility = View.VISIBLE
                   }else{
                       holder.childofChildRV.visibility = View.INVISIBLE
                   }
               }

我知道代码是用 Kotlin 编写的，但我也可以接受 Java 答案。

为什么不简单地传递一个对象

private var time: ArrayList<YourClass> 

而不是

private var time: ArrayList<String>

在我看来这是最简单的解决方案
