How to add strings values to arrayListOf in Kotlin?

Question

I am translating an app in Kotlin using two different files of strings but in arrayListOf there are string like this:

var language = arrayListOf<String>(
    "Profile Settings",
    "About Us",
    "Rate Us",
    "Language",
    "Push Notification",
    "Terms of Service",
    "Privacy Policy",
    "Help (FAQ)",
    "Support"
)

i want to change it to be responsive to the language chosen for example:

var language = arrayListOf<String>(
    "@strings/Profile Settings",
    
)

is it possible to do it from arrayListOf? or there is another way to do it?

@string is XML syntax for a String resource. To access the String resources in Kotlin, you use R.string. The R values are Ints, so you need to convert them to Strings, which you can do using map to avoid having to repeat code for every element.

val language: List<String> = listOf(
    R.string.profileSettings,
    //...
).map { requireContext().getString(it) }

If you do this in a property instead of in a function, you need to wrap the whole declaration in by lazy because the context is not available until the Fragment is attached.

In an Activity, you can omit requireContext(). since the Activity itself is its own Context, so it can be shortened to .map(::getString).

You must have a syntax issue. Maybe you used the wrong kind of brackets.

You can re-write the Array-list like this:

var language = arrayListOf<String>(
   getString(R.string.profile_settings),
   .... 
)
