Я так понимаю проблема с отображением recyclerView, и в интернете все предлагают подключить старую библиотеку. Вот у меня с новой библиотекой. Сам код на Kotlin

RecyclerView крутится в фрагменте

build gradle:

implementation 'androidx.recyclerview:recyclerview:1.1.0'

xml фрагмента:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/constraintLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

код в фрагменте:

import androidx.recyclerview.widget.RecyclerView


val recyclerView: RecyclerView = view.findViewById(R.id.recyclerView1)
        recyclerView.layoutManager = LinearLayoutManager(activity)
        recyclerView.adapter = MyAdapter(list)

Адаптер в фрагменте:

class MyAdapter(private val values: MutableList<String>) : RecyclerView.Adapter<Adapter.ViewHolder>() {

        override fun getItemCount() = values.size

        override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
            val itemView = LayoutInflater.from(parent.context).inflate(R.layout.list_two, parent, false)
            return ViewHolder(itemView)
        }

        override fun onBindViewHolder(holder: ViewHolder, position: Int) {
            holder.textView?.text = values[position].toString()
            holder.textView?.setOnClickListener {
                Toast.makeText(it.context, values[position], Toast.LENGTH_LONG).show()
            }
        }

        class ViewHolder(itemView: View?) : RecyclerView.ViewHolder(itemView!!) {
            var textView: TextView? = null
            init {
                textView = itemView?.findViewById(R.id.textView4)
            }
        }
    }

list_two
