How to make variable from an array

Question

I'm using an array like below and I'm using "category" variable after that without problem.

var category = resources.getStringArray(R.array.**main_menu**)

My question is, how can I make a variable "main_menu"? There are other arrays also exist and I want to send their names as a varible in this line?

I tried the code below, but surely it's not working, because it's text and "getStringArray" expecting Int.

var **text** = R.array.main_menu
var mainCategory = resources.getStringArray(**text**)

Yes, there are 10 other arrays exist, so I want to send these arrays to this line. — sleepy

You can try context.getPackageName(). You can use same context which you use to get resources. — Natig Babayev

By using getIdentifier() method, you can get the integer id of your resource. That method accepts three parameters:

Name of the resource as string
Type of the resource, which is in your case "array"
Package name

By using the resource id returned from resources.getIdentifier(arrayName, "array", getPackageName()), you can get array.

Here is full code:

var arrayName = "main_menu"
val resId = resources.getIdentifier(arrayName, "array", context.packageName)
var mainCategory = resources.getStringArray(resId)
