Question

我有一个对话片段的片段

在对话框片段中有一个编辑文本和按钮

我想在推送按钮“发送”时从dialogfragment的Edittext向mysql数据库发送信息任何人都可以帮我这个片段的代码 m php文件工作正常，我的服务器也用登录和注册来测试它

我认为我的应用程序不会将请求发送到服务器。

尝试调试。无需调试如何找到任何错误。当volley没有返回成功响应时，你可以在这里查看错误。

private void callLoginService() {
        try {
            if (globalInstance.isNetworkAvailable(MainActivity.this)) {
                String logindataxml = loginXML();
                if (logindataxml.length() < 0) {
                    return;
                } else {
                    RequestQueue queue = Volley.newRequestQueue(this);
                    JSONObject obj = new JSONObject();
                    obj.put("xmlData", logindataxml);
                    JsonObjectRequest postRequest = new JsonObjectRequest(Constants.url.login, obj,
                            new Response.Listener<JSONObject>() {
                                @Override
                                public void onResponse(JSONObject response) {

                                   } catch (JSONException e) {
                                        e.printStackTrace();
                                    }

                                }
                            },
                            new Response.ErrorListener() {
                                @Override
                                public void onErrorResponse(VolleyError error) {
                                    String msg = error.getMessage();
                                    Log.d("Error.Response", "");
                                }
                            }
                    );

                  queue.add(postRequest);
                }
            }
        } catch (Exception e) {
            globalInstance.writeLogs(this, new Object() {
            }.getClass().getEnclosingMethod().getName(), true, e.toString(), Constants.LogType.ERROR_LOG);

        }
    }
