In Java we are told to strictly avoid using enums on Android because they take up twice the memory.
这也适用于Kotlin 的enum class人吗？Kotlin enum会被编译成Java enum吗？

It would appear so, yes.
我在Kotlin 创作了这个:
enum class Thingies {
Red,
Green,
Blue
}
And decompiled it with javap -v, and here is the header:
public final class Thingies extends java.lang.Enum<Thingies>
minor version: 0
major version: 52
flags: ACC_PUBLIC, ACC_FINAL, ACC_SUPER, ACC_ENUM
一句话:它们是一样的，所以你可能必须以同样的方式对待它们.
