- create new folder with values in resources folder in project with extension your language code
For example:
My language is Czech (cs)
I have to create the folder values-cs in res folder
Into every values folder put strings.xml file
Translate every string from values folder into your locale.
If user selected your locale in device settings, application selects a string from the correct (proper) folder.
For example:
My language is Czech (cs)
I have to create the folder values-cs in res folder
// for locale English is default
/MyProject/res/values
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">App English default</string>
<string name="action_settings">Settings English default</string>
<string name="hello_world">Hello world</string>
</resources>
// for locale Czech (cs)
/MyProject/res/values-cs
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">Aplikace česky cs</string>
<string name="action_settings">Nastavení česky</string>
<string name="hello_world">Ahoj světe!</string>
</resources>
// for locale English US (r is region)
/MyProject/res/values-en-rUS
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">App English Us locale</string>
<string name="action_settings">Settings English Us locale</string>
<string name="hello_world">Hello world from USA :)</string>
</resources>
