How to detect if the language is English (All variants) on Android?

Question

I want to show a button only for English users, is there a way to detect the language settings?

I know how to get the current Locale, but I don't know if comparing it against Locale.English is sufficient, since there must be a lot of English variations etc.

Anyone experience doing this?

Answer 1

From the Locale docs:

The language codes are two-letter lowercase ISO language codes (such as "en") as defined by ISO 639-1. The country codes are two-letter uppercase ISO country codes (such as "US") as defined by ISO 3166-1.

This means that

Locale.getDefault().getLanguage().equals("en")

should be true. I'd be careful with hiding/showing UI only by default Locale though. Many countries may have many users that prefer another language, but are perfectly fluent in English.

Answer 2

Locale.getDefault().getDisplayLanguage() will give your default language of your device

Example

System.out.println("My locale::"+Locale.getDefault().getDisplayLanguage());

Result

My locale::English

Answer 3

What about using Java's startsWith() function to check whether the current locale is an English variant or not.

Locale.getDefault().getLanguage().startsWith("en")
