Question

当我点击按钮时，我正在实现一个我想更改按钮文本的应用程序。到目前为止，我已尝试过以下代码，请告诉我哪里出错了。

private void shortlist(){

        StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>     () {
            @Override
            public void onResponse(String response) {
                Log.e("short response-------",response);
                if(response.equalsIgnoreCase("success")) {
                    btnSort.setText("shortlisted");
                    btnSort.setEnabled(false);
                }

                Toast.makeText(getContext(), response, Toast.LENGTH_LONG).show();
            }
        },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        Toast.makeText(getContext(), error.toString(), Toast.LENGTH_LONG).show();
                    }
                }) {
            @Override
            protected Map<String, String> getParams() {
                Map<String, String> params = new HashMap<String, String>();
                params.put(KEY_MATRI_ID_BY,matri_id_by);
                params.put(KEY_MATRI_ID_TO,matri_id_to);
                return params;
            }
        };
        RequestQueue requestQueue = Volley.newRequestQueue(getContext());
        requestQueue.add(stringRequest);
    }
