For Kotlin try it out

class DataForm : Fragment() {
    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        Tasks(this).getData()
    }

    fun getResponse(response: String) {
        // code
    }
}

class Tasks(private val context: Any) {
    fun getData() {

        val getContext = (context as DataForm).activity
        val getFragment = (context as DataForm)

        val responseListener = Response.Listener { response ->
            getFragment.getResponse(response)
        }

        val errorListener = Response.ErrorListener { error ->
            error.printStackTrace();
        }

        val stringRequest = StringRequest(Request.Method.GET, url, responseListener, errorListener)
        Volley.newRequestQueue(getContext).add(stringRequest)
    }
}
