Kotlin从Java访问内部类中的常量

Question

NOTE : This issue has been resolved since Kotlin 1.0 beta version (at least). Keeping the rest of the contents intact for historical reason.

---

I'm using Kotlin with Android and I'm trying to use some constants from the SDK, like this one:

MediaRecorder.AudioSource.MIC;

It doesn't see AudioSource, so it doesn't see the MIC as well. I've tried changing the imports, cleaning the project. Nothing worked so far. I've temporarily solved it by importing it in a Java class, which worked just fine, and then I just refer to my Java class from my Kotlin file,but I would really like to know why this happens and how I can avoid having that Java class.

Answer 1

I can confirm, accessing MediaRecorder.AudioSource.MIC doesn't work. However, if you import android.media.MediaRecorder.AudioSource manually, you can access AudioSource.MIC .

Answer 2

我可以确认它在Kotlin Beta 4中有效，也可能在旧版本上有效。
