Create a new activity called ProfileActivity.kt, and here is the code:

class ProfileActivity : AppCompatActivity() {        private var username: String = ""    private var password: String = ""    override fun onCreate(savedInstanceState: Bundle?) {        super.onCreate(savedInstanceState)        setContentView(R.layout.activity_profile)        setTitleName()         username = PrefUtils.getUsername(this)!!        password = PrefUtils.getPassword(this)!!    }}
