How to add a button at the end of a recycler view (kotlin)?

Issue

I'm gonna add a button at the end of my recycler view and i don't know how to do it . i will appreciate you if you teach me .

this is my main activity code :

class MainActivity : AppCompatActivity() {
private var number: Int = 0
private lateinit var name: String

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    val myRecyclerView = findViewById<RecyclerView>(R.id.recyclerView)
    val myViewModel = ViewModel()
    myRecyclerView.layoutManager = LinearLayoutManager(this)

    myViewModel.getUserData()




    myViewModel.myList.observe(this) {
     
        myRecyclerView.adapter = MyAdapter(it)
    }


}

and this is my adapter code :

class MyAdapter(private val myList: List<Player>) : RecyclerView.Adapter<MyHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyHolder {
    val myLayoutInflater = LayoutInflater.from(parent.context)
    val myView = myLayoutInflater.inflate(R.layout.view_for_rv, parent, false)
    return MyHolder(myView)

}

override fun onBindViewHolder(holder: MyHolder, position: Int) {
    val item = myList[position]
    holder.bind(item)


}

override fun getItemCount(): Int {
    return myList.size
}

and my holder class :

class MyHolder(view: View) : RecyclerView.ViewHolder(view) {
private val playerNumber  = view.findViewById<TextView>(R.id.tvNumber)
private val playerName = view.findViewById<TextView>(R.id.tvName)

fun bind(item : Player){
    playerName.text=item.name
    playerNumber.text=item.number.toString()
}

Solution

You will achieve this by adding the RecyclerView in a parent NestedScrollView and then place the Button below the RecyclerView.

So your code should look like this

<androidx.core.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <androidx.recyclerview.widget.RecyclerView
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </LinearLayout>
</androidx.core.widget.NestedScrollView>

NOTE

Add recyclerView.nestedScrollingEnabled = false for scroll to work for sdk 21
