推荐答案

使用Kotlin语法，在Kotlin中访问字符串值的工作原理与在Java中完全相同:

Accessing string values in Kotlin works exactly the same as it does in Java, just with Kotlin syntax:

val string: String = getString(R.string.your_string_id)

(这假设您的代码在Android Activity中，或者是从Context继承的类似类.如果没有，则需要从某个地方获取Context实例，并将其更改为myContext.getString(...) )

(This assumes that your code is inside an Android Activity, or a similar class that inherits from Context. If not, you need to get a Context instance from somewhere, and change it to myContext.getString(...).)
