How to make phone call using intent after getting contact name and number

Question

I am a newbie on android. I already made an activity that shows all my contact list and number inside Linear Layout. How can I make phone call using intent after I click the Linear Layout? I don't know where to put the setOnclickListener in my code. So here I share all of the source-code.

XML

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

              android:layout_height="wrap_content"
              android:clickable="true"
              android:orientation="vertical">

    <TextView
            android:id="@+id/itemName"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="8dp"
            android:text="Nama : "
            style="@style/Base.TextAppearance.AppCompat.Headline"/>

    <TextView

You can put yout click action inside the onBind in recycler view adapter.

class myHolder(view: View):RecyclerView.ViewHolder(view) {
    private  val contactName = view.itemName
    private  val contactNumber = view.itemNumber

    fun bindContact(tmp: myContact) {
        contactName.text = "${contactName.text} ${tmp.nama}"
        contactNumber.text = "${contactNumber.text} ${tmp.nomorHp}"

        view.setOnClickListener {
           // YOUR ACTION HERE.
        }
    }
}
