收到Firebase通知时通知列表适配器

Question

我正在尝试在收到通知时向列表视图添加新元素（没有用户点击）。

我需要收听我的片段收到的通知，然后根据通知信息向适配器添加新元素。

如何从片段中收听新通知？

我已经实施了Firebase云消息传递架构。

-MyFirebaseMessagingService ......

有人可以帮助我吗？

Answer 1

 public String push_receiver = "com.example.fragment.GCMBroadCast";
    @Override
    public void onResume() {
        super.onResume();
        mActivity.registerReceiver(broadcastReceiver, new IntentFilter(push_receiver_expositor));
    }

    /** receiving GCM broadcast */
    private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {

            }
        };

你需要在你的片段中制作一个广播接收器，当你的firebase通知一次收到时，你也可以通过下面的行调用你的片段接收器

public String push_receiver = "com.example.fragment.GCMBroadCast";
Intent intent = new Intent(push_receiver);
                    intent.putExtra("extra", bundle);
                    sendBroadcast(intent);

在片段中将Arraylist和adapter声明为public，并在MyFirebaseMessagingService中更新此方法

private void handleNotification(final String message) {

if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {

//add message to list
Fragment.list.add(message);
Fragment.adapter.notifyDataSetChanged();
    Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
       pushNotification.putExtra("message", message);                                                                                                                                         LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);

        // play notification sound
        NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext());
        notificationUtils.playNotificationSound();

    } else {
        // If the app is in background, firebase itself handles the notification
    }
}

1. 创建静态方法并从MyFirebaseMessagingService调用它。 reference1，reference2
2. 创建BroadcastReceiver
3. 使用EventBus。
