Firebase通知onMessageReceed显示与应用程序在后台时相同的通知

Question

我从控制台向我的应用程序发送消息，当它在后台时，我设法让应用程序做出我想要的反应。所以基本上SDK会显示一个通知，当用户点击它并启动应用程序时，我会使用一些自定义数据字段来构建对话框消息。

Answer 1

当然有。只需重写FirebaseMessagingService.onMessageReceed并从Firebase Cloud Messaging文档中获取通知正文，如本例所示：

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    // TODO(developer): Handle FCM messages here.
    // If the application is in the foreground handle both data and notification messages here.
    // Also if you intend on generating your own notifications as a result of a received FCM
    // message, here is where that should be initiated. See sendNotification method below.
    Log.d(TAG, "From: " + remoteMessage.getFrom());
    Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
}

请参见“Override OnMessageReceed”下的Firebase Cloud Messaging文档，用于在Android上接收下游消息。
