I need to pass a user input from one activity to another in kotlin

Question

So I tried the intent method but I always get a red underline under the "putExtra"

here is the code I tried:

next.setOnClickListener {
  var i=Intent(this,Screen6::class.java)
  i.putExtra("ID", id)
}

How can I do that?

EDIT: the id needed the function to.toString() but now I need to get it from the other activity how is that possible

what error does android studio show ? have you tried to research that error a bit more to see what you can find ? — a_local_nobody, Jun 23 '20 at 12:33
`i.putExtra("ID", id)` the "id" at the end did you assign it to something such as `String id` etc? — Ruben Meiring, Jun 23 '20 at 12:38
You might need to read more about android programming, Parcelable is quite a basic concept, this is a good introduction: https://www.vogella.com/tutorials/AndroidParcelable/article.html — al3c, Jun 23 '20 at 12:44
If you're trying to figure out how to use the framework in the first place (e.g. to learn what parcelization is) I don't think the choice of language in the article is incredibly important. — Salem, Jun 23 '20 at 14:23

You can simply use the intents to send data and parameters from one activity to another activity in kotlin

val intent = Intent(this@OneActivity,TwoActivity::class.java);
intent.putExtra("username", userName)
startActivity(intent);

Where "username" will be key and userName will be actual data you will pass.

In the other activity, you use the below code Fragment ` val ty = activity?.intent ty?.getStringExtra("username")` for Activity ` val ty = intent ty?.getStringExtra("username")` from my code am passing a String value that's why I used double "" and also received it with the getString method, you can also work with other data Type – wise4rmgod Jun 23 '20 at 13:17
