Hi. I'm having some problems with using listpreference.setValue or setIndexValue.
None of the methods that I need to alter the values of a listpreference programmatically doesn't seem to be available.

My class extends Preferencefragmentcompat

Thanks
Stefan

Sorry, I haven't noticed how your question was related to Kotlin.
ListPreference has setValue(String) but not setIndexValue (it is named setValueIndex(Int)).
In Kotlin, when a class has 2 methods like the following : Foo getFoo(), setFoo( Foo f), Kotlin converts it to a property, so you can directly write obj.foo = ... instead of obj.setFoo(...).
That's the case for `ListPreference`: it has both getValue() and setValue(String), thus the IDE suggests you "value" instead of "setValue(String)".

If you are still unable to find those methods on ListPreference, maybe you could share some code ?

Thank you for that, I'm still pretty new at kotlin and it's still a bit confusing.

I'm unable to get anything other than setDefaultValue.

I'll try to jot down some code.
