Question

我在我的应用中使用了适用于Android的Facebook SDK。我似乎无法找到有关如何使用SDK代码获取通知的任何示例或文档。我有权限“manage_notifications”设置，我假设我需要使用.request（）方法，但是graphPath参数使我失望。

有没有人举例说明如何使用面向Android的Facebook SDK获取Facebook通知？

Answer 1

虽然其他答案很有帮助，但我所寻找的是Android Code的一个例子。我已经弄明白了，并在此发布。下面的代码获取登录/验证用户通知。

//Initialze your Facebook object, etc.
Facebook _facebook = ...
...
Bundle bundle = new Bundle();
bundle.putString(Facebook.TOKEN, _accessToken);
String result = _facebook.request("me/notifications", bundle, "GET");

然后你需要解析字符串“result”。它是json格式。以下是一个示例：

JSONObject jsonObjectResults = new JSONObject(result);
JSONArray jsonNotificationDataArray = jsonObjectResults.getJSONArray("data");
for (int i=0;i<jsonNotificationDataArray.length();i++)
{
    JSONObject jsonNotificationData = jsonNotificationDataArray.getJSONObject(i);
    if (_debug) Log.v("Title: " + jsonNotificationData.getString("title"));
}

我希望其他人觉得这很有用。

默认情况下，/ USER_ID / notifications端点仅包含未读通知（即，如果Facebook.com顶部的第三颗宝石点亮并且内部有红色数字，则只会有返回值）

如果您还要包含用户已阅读的通知，您可以向/USER_ID/notifications?include_read=1发出请求 - manage_notifications是对此的正确扩展权限

您可以检查Facebook SDK 3.0的会话对象以确保会话已打开。之后，您可以借助以下代码获取JSON数据：

    Session session = Session.getActiveSession();
    if (session.isOpened()) 
    {
        //access_token = session.getAccessToken();
        Request graphRequest = Request.newGraphPathRequest(session, "me/home", new    
        Request.Callback() 
    {
    public void onCompleted(Response response) 
            {
                //Create the GraphObject from the response
                GraphObject responseGraphObject = response.getGraphObject();

                //Create the JSON object
                JSONObject json = responseGraphObject.getInnerJSONObject();
                Log.i("JSON", json.toString());
                try 
                {
                    YOUR_JSON_ARRAY= json.getJSONArray("data");
                } 
                catch (JSONException e) 
                {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        });
    Request.executeBatchAsync(graphRequest); 
     }

您还可以使用FQL查询。查询格式为

SELECT notification_id, sender_id, title_html, body_html, href
FROM notification
WHERE recipient_id=userid
AND is_unread = 1
AND is_hidden = 0

请参阅此页面了解详情http://developers.facebook.com/docs/reference/fql/notification/

可以在实现BaseRequestListener的侦听器的onComplete（）中接收此查询的结果。

这是我收到通知的方式

final Session session =Session.getActiveSession();
            if(session.isOpened()){  
                String aaa=new String();
                aaa="SELECT title_text,updated_time FROM notification WHERE recipient_id=me() AND is_unread=1";
                Bundle params = new Bundle();
                params.putString("q", aaa);
                     new Request(session,"/fql",params,HttpMethod.GET,new Request.Callback() {
                                 public void onCompleted(Response response) {
                                     try
                                     {
                                        GraphObject go  = response.getGraphObject();
                                        JSONObject  jso = go.getInnerJSONObject();
                                        JSONArray   arr = jso.getJSONArray( "data" );
                                        String splitting=arr.toString().replaceAll("\\\\|\\{|\\}|\\[|\\]", "");
                                        String[] arrayresponse=splitting.split("\\,");
                                        String s = "";
                                        for (int i = 0; i < arrayresponse.length; i++) {
                                            if (arrayresponse[i].length()>13){
                                                if (arrayresponse[i].substring(1,13).equals("updated_time"))
                                                    s+="* "+getDate(Long.valueOf(arrayresponse[i].substring(15,arrayresponse[i].length())))+"\n";
                                                else
                                                    s+="   "+arrayresponse[i].substring(14,arrayresponse[i].length()-1)+"\n\n";

                                            }
                                        }
                                        text2.setVisibility(View.VISIBLE);
                                        NotificationMessage.setVisibility(View.VISIBLE);
                                        NotificationMessage.setMovementMethod(new ScrollingMovementMethod());
                                        NotificationMessage.setText(s);
                                        readMailBox(session);

                                     }catch ( Throwable t )
                                     {
                                         t.printStackTrace();
                                     }


                                 }
                             }  
                     ).executeAsync();
            }
             else{
    //           NotificationMessage.setVisibility(View.INVISIBLE);
                 Log.i(TAG, "Logged out...");
             }
     }
