Develop Reference

keep getting error "Unresolved reference: valueOf"

In in the notes portion of my app i get the error "Unresolved reference: valueOf" in my EquipmentTrackerAllnotes.kt file.
the way my app operates is when you open the app initially it opens up to the dashboard the main home screen, then there is a navigation drawer on the side. One of the fragments in the navigation drawer is my "EquipmentTracker" aka the area where you can make notes of equipment the user may have. In side there you can add notes, delete and edit.
I'm open ears to any recommendations on possible changes i should make as well. But for now my main focus is fixing this error listed above.

Recycler View not getting Displayed (in Card View) for weather app. Tried solutions from Stack Overflow. Nothing is Working

I am trying to develop an application in android with the help of Geeks for Geeks tutorials. I am still learning how to develop android apps. It is a simple weather app where I need to display forecast in recycler view with the help of card view. The code is as shown from the video, but still the recycler view is not getting displayed. API url is also working. There is no error shown.
App Permissions - Location and Internet (Added in Manifest)
It was a request to please help me out with this issue.
Please do reply.

This will work -
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycle_news, parent, false);
Second parameter suppose to be a ViewGroup which is parent here.
Reference

Add ViewGroup parent as second parameter
