What is the bast way to handle DropDownPreference integer values

[NLLAPPS]

I have a DropDownPreference with integer values. Android needs string-array for values to be used and that crates an issue where I have to define preference model member as var myPref: String by stringPref.

Is there a correct way of of accessing this preference apart from converting it to Int in my code?

You can use pref value as the backing field of your value.

object Settings : KotprefModel() {
    private var internalMyPref: String by stringPref(key = "myPref")
    var myPref: Int
        get() = internalMyPref.toInt()
        set(value) {
            internalMyPref = value.toString()
        }
}

That's right. Thank you.

Hi again, I don't suppose there is way to do above and observe with live-data.
Because myPref have no delegation, I get "failed to get preference key, check property 'pref' is delegated to Kotpref.'

Am I correct?

Hi,

You are correct. Currently, Kotpref can't observe directly with LiveData.
