从kotlin调用java varargs方法

我有一个Java功能：

public static void initialize(@NonNull Activity activity, Settings... settings) {} 

我想从kotlin中调用它：

 fun initialize(activity: Activity, vararg settings: settings) = JavaClass.initialize(activity, settings) 

但它不能编译，告诉我有类型不匹配，需要Settings ，但参数是kotlin.Array<out Settings>

我看到它试图与signture匹配

 public static void initialize(@NonNull Activity activity, Settings settings) {} 

但我想用

 public static void initialize(@NonNull Activity activity, Settings[] settings) {}

您应该使用以下语法：

 fun initialize(activity: Activity, vararg settings: settings) = JavaClass.initialize(activity, *settings)
