Java отражение для инициализации Kotlin объект не выполняется, когда объект содержит 'init'

Question

У меня есть некоторый код Java, который использует отражение для создания нового объекта. Новый объект - это объект, который я кодировал в Kotlin. Код работает нормально, если только в моем Kotlin классе я не использую init, чтобы попытаться инициализировать некоторые переменные.

например:

private BaseClass constructViewHolderClass(View itemView, int viewType) {
    View itemView = ...

    Class<? extends BaseClass> baseClass = ChildBaseClass.class;

    Constructor<? extends BaseClass> ctor;

    ctor = baseClass.getConstructor(View.class);

    return (BaseClass) ctor.newInstance(new Object[]{itemView});
}

Kotlin класс, который работает:

class ChildBaseClass(itemView: View) : BaseClass(itemView) {

    var imageView: ImageView = itemView.findViewById(R.id.image_view)
    var circularProgressDrawable = CircularProgressDrawable(itemView.context)
}

Kotlin класс, который НЕ работает:

class ChildBaseClass(itemView: View) : BaseClass(itemView) {

    var imageView: ImageView = itemView.findViewById(R.id.image_view)
    var circularProgressDrawable = CircularProgressDrawable(itemView.context)

    init {
        circularProgressDrawable.strokeWidth = 5f
        circularProgressDrawable.centerRadius = 30f
        circularProgressDrawable.start()
    }
}

Исключение составляет java.lang.IllegalArgumentException: class java.lang.reflect.InvocationTargetException

Answer 1

Извините всех, я пропустил одну строку в функции init, которая фактически вызывает проблему:

circularProgressDrawable.colorFilter = BlendModeColorFilter(itemView.context.resources.getColor(R.color.text_default), BlendMode.SRC_IN)

Не уверен, почему это вызывает проблему , но посмотрю на это.

Извините, что зря потратил время.
