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)!!
    }
}
