How can i concatenate using resource string with placeholders?

Question

I have a function that displays the username. It works fine but I am getting this warning and I was wondering how to solve it.

Answer 1

Define the string in the strings.xml, do not hardcode it in the code. "Welcome, %s"

Then use it in the code:

getString(R.string.welcome_message).format(userProfile?.username)

Answer 2

Declare your string like this Welcome %1$s And when you want to use it

context.getString(R.string.welcome,userProfile?.username)
