如何在Kotlin回调中做到这一点？

如何解决如何在Kotlin回调中做到这一点？

请问我该如何用kotlin的Java语言编写回调，代码基本上是基于对凌空库发出请求的情况，我需要通过接口获取响应，对此我将不胜感激>

...
    public void stringRequest(String url,final VolleyStringResponse volleyResponse){
        StringRequest stringRequest = new StringRequest(Request.Method.GET,url,new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                volleyResponse.onSuccess(response);
            }
        },new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                volleyResponse.onError(error);
            }
        });
        VolleySingleton.getInstance(context).addToRequestQueue(stringRequest);
    }

    //Interface

    public interface VolleyStringResponse{
        void onSuccess(String response);
        void onError(VolleyError error);
    }

MainActivity类

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        VolleyRequest volleyRequest = new VolleyRequest(this);
        volleyRequest.stringRequest(getUrlAPI(),new VolleyRequest.VolleyStringResponse() {
            final TextView textView = findViewById(R.id.text);
            @Override
            public void onSuccess(String response) {
                    textView.setText(response);
            }

            @Override
            public void onError(VolleyError error) {
                textView.setText(error.getMessage());
            }
        });
    }
}
