如何在Android Studio项目中添加Kotlin类? [英] How to add a Kotlin class in an Android Studio project?

问题描述

我使用Android Studio已有一段时间了.最近，我听说过有关Kotlin编程语言的信息，我想尝试在我的项目中加入Kotlin语言的课程.

I have been working with Android Studio for a while. Recently I have heard about kotlin programming language and I wanted to try to include a class in kotlin language to my project.

存在一个问题，例如，当我要创建新的Activity时，会自动生成 .java 类.另外，我也看不到手动创建 .kt (kotlin)文件的方法.

There is the problem that whenevr I want to create a new Activity for example, the .java class is auto-generated. Also I see no way to cretae a .kt (kotlin) file manually.

那么有谁知道如何在Android Studio中设置 .kt 文件，以便能够用kotlin语言的代码填充该文件?

So does anyone know how to setup a .kt file in Android Studio, so that I am able to fill it with code in kotlin language?
