How can I change language of my application [duplicate]

Answer 1

You can set the locale.

    Resources res = context.getResources();
    // Change locale settings in the app.
    DisplayMetrics dm = res.getDisplayMetrics();
    android.content.res.Configuration conf = res.getConfiguration();
    conf.locale = new Locale(language_code.toLowerCase());
    res.updateConfiguration(conf, dm);

If you have language specific content - you can change that base on the setting. for more detail you can see Locale and this also
