android – 使用JsonObjectRequest时的编译错误

我正在使用mcxiaoke / android-volley library.Im获取编译错误

Error:(77,37) error: reference to JsonObjectRequest is ambiguous,both constructor 
JsonObjectRequest(int,String,Listener<JSONObject>,ErrorListener) in JsonObjectRequest and constructor 
JsonObjectRequest(int,JSONObject,ErrorListener) in JsonObjectRequest match

这是我的代码.我不知道是什么错.任何帮助赞赏

JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET,getRequestUrl(10),null,new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {


        }
    },new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

        }
    });

解决方法

将null转换为字符串或JSONObject,它应该可以正常工作,我想.

new JsonObjectRequest(Request.Method.GET,(String)null,new Response.Listener<JSONObject>()
