Answer 2

Your intent is not formatted correctly. This is how it's supposed to be:
Intent (this, YourActivity::class.java)
So your code should look like this:
when (item.itemId) {
R.id.flightarrbeforbgw ->{
this.startActivity(Intent(this,FlightsArrivelBeforBGW::class.java))
return true
}
else -> super.onOptionsItemSelected(item)
}
