Follow this Link: Android : translate the language of whole app on click

Then Do like this, Add the string values for each locale into the appropriate file.

English (default locale), /values/strings.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="title">My Application</string>
    <string name="hello_world">GoodMorning</string>
</resources>

Tamil, /values-tl/strings.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="title">My Application</string>
    <string name="hello_world">Kaalai vanakkam</string>
</resources>
