Hey Guys, I have string which is coming from server.

val string = "2.2"

I want to show in textview like 2.2 . But if my string is 2.00 it will show 2 in my textview. How can I do this in kotlin efficient way?

[Tim Oltjenbruns]

Two options: Format with kotlin or format with android strings.xml

If you plan on supporting multiple languages, consider using Android strings.xml

Ok

Convert it to double and use a NumberFormat for this. You can do something like this if you have a locale. Remember to check for empty and non numeric values in your string when converting to double.

NumberFormat.getInstance(Locale("en", "US"))
        .format(yourStringInDouble).replace(".00", "")

Yep! Abinet’s is the way to go if you do it via Kotlin. Make sure to use the user device’s locale though, and not hardcode it to english.

@Tim Oltjenbruns what do you mean by not harcode it to english ?

[Abinet Zelalem]

Don’t use Locale("en", "US"), use the Locale of the device

[Tim Oltjenbruns]

The above example uses Locale("en", "US")

[Tim Oltjenbruns]

This hardcodes the number formatting to english

[Tim Oltjenbruns]

Yep! Beat me to it lol

Ok got it thanks 😊

With locale set to device, locales using , for decimals would show 2,00.
