Android Volley没有调用onResponse或onErrorResponse方法

Volley未在调试和正常运行模式下进入

onResponse

或

onErrorResponse

方法。 最后一个日志是：

Request is: https://www.google.com/

这是我的主要活动。课堂

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                String urlGoogle = "https://www.google.com/";

                Log.println(Log.INFO, null, "Request is: " + urlGoogle);

                JsonObjectRequest jsonObjectRequest = new JsonObjectRequest
                        (Request.Method.GET, urlGoogle, null, new Response.Listener<JSONObject>() {

                            @Override
                            public void onResponse(JSONObject response) {
                                Log.println(Log.INFO, null, "Response is: " + response.toString());
                            }
                        }, new Response.ErrorListener() {

                            @Override
                            public void onErrorResponse(VolleyError error) {
                                Log.println(Log.INFO, null, "Error response is: " + error.toString());
                            }
                        });
            }
        });
    }
}

编辑：

我使用返回JSON的站点进行了测试。 例如：

EDIT2:

我用不同的网络交换设备，它是一样的

EDIT3:

我把截击降到了1.0.0版本。没有更改。

您只是创建了一个JsonObjectRequest对象，但没有执行它，要执行请求，您需要将它添加到请求队列中- 在初始化JsonObjectRequest之后添加这两行-

    RequestQueue queue = Volley.newRequestQueue(this);
    queue.add(jsonObjectRequest);

因为你没有从Google.com得到任何回应。尝试实际返回Json或字符串的内容。@Parth我尝试了返回Json的站点，但结果是一样的。@januszj您尝试了哪个站点？你能把它贴出来吗url@varunkr因为你没有从Google.com得到任何回应。尝试实际返回Json或字符串的内容。@Parth我尝试了返回Json的站点，但结果是一样的。@januszj您尝试了哪个站点？你能把它贴出来吗url@varunkr及
