how could I run some code after constructor like in Java?

public class CustomView extends View {
    public CustomView(Context context) {
        this(context,null);
    }

    public CustomView(Context context, @Nullable AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public CustomView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        //some custom code
    }
}

I try init{} block, but it run before constructor.

class CustomView @JvmOverloads constructor(
    context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
) : View(context, attrs, defStyleAttr) {
    init {
        // this place is run before super constructor
    }
}

class CustomView : View {
    constructor(context: Context, attrs: AttributeSet, defStyle: Int) : super(context, attrs, defStyle) {
        //some custom code
    }
    constructor(context: Context, attrs: AttributeSet) : super(context, attrs, 0) {
    }

    constructor(context: Context?) : super(context) {
    }
}

@CodeIdeal This is the other way to implement the same code.
Hope this helps.

Nothing is ever run before the super constructor. That isn't allowed on the JVM, whether you write you code in Java or Kotlin

@Kavita is there any way to complete this with in @JvmOverloads annotation.

Hi @CodeIdeal, We use @JvmOverloads annotation in Kotlin for interoperating with Java code.
Here if you are implementing View class's constructor traditionally, then there is no need to use @JvmOverloads.
