回答1:

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)

回答2:

If you need to access the entire array:

val data= resources.getStringArray(R.array.array_id)

回答3:

If you wanted to access String out of a context or Activity (e.g Data Model Class) you can achieve like this:

Resources.getSystem().getString(R.string.pay)

EDIT: It's only for system-wide resources, not Application resources
