Вы можете сделать это двумя способами:
FIRST:
Поместите все или именно то, что вы хотите, в «ScrollView», и ваши элементы будутпрокручивается независимо от того, сколько предметов вы кладете.
Пример:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- PUT EVERYTHING YOU WANT HERE -->
</ScrollView>
</RelativeLayout>
ВТОРОЙ:
Положите все своиэлементы в ListView с использованием адаптера и элемента для списка:
item_list.xml (в res> layout> New> XML> Layout XML File):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_margin="20dp"
android:id="@+id/item_text"
android:text="Test"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
ваш список адаптеров (в java> yourPackageName> new> Kotlin File / Class):
import android.content.Context
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.BaseAdapter
import android.widget.TextView
class ListAdapter (private val context: Context, private val listItems: ArrayList<String>) : BaseAdapter() {
override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {
val view = LayoutInflater.from(context).inflate(R.layout.item_list, null)
val text = view.findViewById<TextView>(R.id.item_text)
text.text = listItems[position]
return view
}
//It doesn't matter right now
override fun getItem(position: Int): Any {
return ""
}
//It doesn't matter right now
override fun getItemId(position: Int): Long {
return 0
}
override fun getCount(): Int {
return listItems.size
}
}
your activity_main.xml (где ListView:)
<?xml version="1.0" encoding="utf-8"?>

MainActivity (где вы вызываете адаптер для ListView):
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import kotlinx.android.synthetic.main.activity_main.*
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val itemsList = ArrayList(
arrayListOf(
"test", "test", "test", "test", "test", "test", "test", "test", "test", "test",
"test", "test", "test", "test", "test", "test", "test", "test", "test", "test",
"test", "test", "test", "test", "test", "test", "test", "test", "test", "test"
)
)
myListView.adapter = ListAdapter(this, itemsList)
}
}
