You can create an array in strings.xml
file or any other xml file (arrays.xml?) like this:
<resources>
<string-array name="listArray">
<item>Headings</item>
<item>Headings and Details</item>
<item>All Data</item>
</string-array>
<string-array name="listValues">
<item>1</item>
<item>2</item>
<item>3</item>
</string-array>
</resources>
