How do I compare image file name (which is set as my ImageView image resource) with a string?

I want to compare currently used image resource with defined string and if it matches then change it to a different image (by clicking a button).
I want to precisely define what image should be displayed next (depending on what button is clicked and which image is currently shown) and I want to do it many times (I know how to switch images with ImageSwitcher or how to change image with a button click, but it's not enough).

Edit:
So far I did something like this. I wanted to get current ImageView content description and then compare it. Bu of course it's not working because it describes the content of ImageView, not the Image itself. But it shows the idea what I want to do.

 val imageView = findViewById(R.id.display) as ImageView
 imageView.setImageResource(R.drawable.one)

 val imageName = imageView.getContentDescription()

 val buttonYes : Button = findViewById(R.id.yesButton)
 val buttonNo : Button = findViewById(R.id.noButton)


 when 
 (imageName.equals(one))-> buttonYes.setOnClickListener imageView.setImageResource(two) 
 (imageName.equals(one))-> buttonNo.setOnClickListener imageView.setImageResource(three) 
 (imageName.equals(two))-> buttonYes.setOnClickListener imageView.setImageResource(five) 
 

A way (or trick) to solve this is to store the name of the drawable in the imageview's tag:

imageView.setImageResource(R.drawable.one)
imageView.tag = "one"

and then compare the tag:

when (imageView.tag.toString()) 
 "one" -> buttonYes.setOnClickListener imageView.setImageResource(two) 
 "two" -> buttonYes.setOnClickListener imageView.setImageResource(five) 

if you don't want to hardcode the id then use this:

imageView.setImageResource(R.drawable.one)
imageView.tag = resources.getResourceEntryName(R.drawable.one)

You can do

 String1 = "nameOne"; 
 String2 = "nameTwo";

and by using in operator

String2 in String1 

Or you can use

"nameOne".contains("nameTwo", ignoreCase = true)
