Butterknife: Can't use Kotlin's List for @BindViews

[ZakTaccardi]

@BindViews(
            R.id.keypadview_0,
            R.id.keypadview_1,
            R.id.keypadview_2,
            R.id.keypadview_3,
            R.id.keypadview_4,
            R.id.keypadview_5,
            R.id.keypadview_6,
            R.id.keypadview_7,
            R.id.keypadview_8,
            R.id.keypadview_9
    )
    lateinit var numberButtons: List<TextView>

Butterknife throws exception @BindViews List or array type must extend from View or be an interface. Workaround is to use kotlin's MutableList or Array."

This is trivial (especially since immutable array works), but it would be nice to support an immutable list in kotlin.

Could you try it with lateinit var numberButtons: List<@JvmSuppressWildcards TextView> and see if that works? My guess is that wildcards are the issue here as they can't be used for arrays or mutable lists.

List<@JvmSuppressWildcards TextView> works!, there's always a Kotlin annotation to the rescue

Just wondering, is @BindViews(...) lateinit var foo: List<View> better for some reason than @BindViews(...) lateinit var foo: Array<View>?

No
