Android Studio and its xml files, how to access them if they are not visible?

Question

Android

I create a project, I created a strings folder in the xml folder, where I will put everything on the shelves.
But neither the folder nor the file is visible.
You need to switch to Project to see the folder and create an xml file in it.

But how can I now turn to it so that it takes the names of the lines from it?

Answer 1

Access to strings goes through the resource manager. And only so. I think it's class R.
