How to format a phone number using PhoneNumberUtils?

Question

How can I format a phone number using PhoneNumberUtils?

E.g.: 1234567890 → (123) 456-7890

Answer 1

We can easily do this by:

val tm = act.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager?
val formattedPhoneNumber= PhoneNumberUtils.formatNumber(phone, tm?.simCountryIso?.toUpperCase())

here, tm?.simCountryIso?.toUpperCase() returns iso code, "in" in my case and we used toUpperCase() to convert it into "IN"

you can also use networkCountryIso instead of simCountryIso.

From doc:

getNetworkCountryIso(): Returns the ISO-3166-1 alpha-2 country code equivalent of the MCC (Mobile Country Code) of the current registered operator or the cell nearby, if available.

getSimCountryIso(): Returns the ISO-3166-1 alpha-2 country code equivalent for the SIM provider's country code.

you can also pass direct iso code, for example:

PhoneNumberUtils.formatNumber("2025550739", "US") // output: (202) 555-0739

Check the list of iso codes.
