Question

我是newbaby android并做一些关于Volley的练习。我写了示例代码：

RequestQueue rq = Volley.newRequestQueue(this);
    String urlStr="https://api.github.com/users/mralexgray/repos";
    JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(
            com.android.volley.Request.Method.GET,urlStr, null,
            new Response.Listener<JSONObject>() {

                @Override
                public void onResponse(JSONObject response) {

                    Log.d("Response", response.toString());
                }
            }, new Response.ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {
                    // TODO Auto-generated method stub
                    Toast.makeText(MainActivity.this, error.toString(),
                            Toast.LENGTH_LONG).show();
                    Log.d("Error!!!!", error.toString());
                }
            });
    rq.add(jsonObjectRequest);

但是程序抛出异常：

如何解决此错误？

响应是Json数组而不是json对象因此修改Volley请求方法如下

RequestQueue rq = Volley.newRequestQueue(this);
    String urlStr = "https://api.github.com/users/mralexgray/repos";
    JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(urlStr,
            new Response.Listener<JSONArray>() {

                @Override
                public void onResponse(JSONArray response) {
                    // TODO Auto-generated method stub
                     Log.d("Response", response.toString());
                }

            }, new Response.ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {
                    // TODO Auto-generated method stub
                     Toast.makeText(MainActivity.this, error.toString(),
                                Toast.LENGTH_LONG).show();
                        Log.d("Error!!!!", error.toString());
                }
            });
    rq.add(jsonArrayRequest);
