Load Spinner with string-array from resources xml

To define string-array in resources xml, edit values/strings.xml to add items of string-array.

<resources>
    <string name="app_name">AndroidSpinner</string>
    <string-array name="weekday">
        <item>Sunday</item>
        <item>Monday</item>
        <item>Tuesday</item>
        <item>Wednesday</item>
        <item>Thursday</item>
        <item>Friday</item>
        <item>Saturday</item>
    </string-array>
</resources>

Edit layout/activity_main.xml to add Spinner with entries to load from string-array.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"

    <TextView

    <Spinner
        android:id="@+id/myspinner"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
