    Toast.makeText(activity, "LOST", Toast.LENGTH_SHORT).show()
}



override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    binding = DataBindingUtil.inflate(inflater, R.layout.fragment_questions, container, false)
    randomQuestion()
    binding.quiz = this
    return binding.root
}

// Buttons for the texViews in the XML
override fun onActivityCreated( savedInstanceState: Bundle?) {
    super.onActivityCreated( savedInstanceState)
    binding.Answer1.setOnClickListener {
        checkTheAnswer(toString())
    }

    binding.Answer2.setOnClickListener {
        checkTheAnswer(toString())
    }

    binding.Answer3.setOnClickListener {
        checkTheAnswer(toString())
    }

}


override fun onDestroyView() {
    super.onDestroyView()
    binding
}

}

I am trying to get the toast to work properly, it just keeps showing either win, if I'm wrong or right, or lost if I'm wrong or right after i change the greater symbol
