Android Firebase-can'；t设置通知的标题和消息

我从PHP服务器向Firebase API发送了以下通知数据：

$fields = [
    'to' => "fcm....",
    'notification' => [
        'title' => 'Test Test Test',
        'body' => 'MSG MSG MSG'
    ],
    'data' => [
        'type' => 'message',
        'sender' => 'someone'
    ],
    'priority' => 'high'
];

在android studio中，这是扩展

FirebaseMessagingService

类的

MyFirebaseMessagingService

类：

public class MyFirebaseMessagingService extends FirebaseMessagingService {
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        sendNotification("Test", "Test");
    }

    private void sendNotification(String title, String message) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_ONE_SHOT);

        String channelId = getString(R.string.notification_channel_id);
        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder =
                new NotificationCompat.Builder(this, channelId)
                        .setSmallIcon(R.drawable.notificatino)
                        .setContentTitle(title)
                        .setContentText(message)
                        .setAutoCancel(true)
                        .setSound(defaultSoundUri)
                        .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(channelId,
                    "Channel human readable title",
                    NotificationManager.IMPORTANCE_DEFAULT);
            notificationManager.createNotificationChannel(channel);
        }

        notificationManager.notify(0, notificationBuilder.build());
    }
}

问题是我保留了从服务器获取标题和消息的通知（title，MSG），而不是将标题和消息作为参数传递给

sendNotification

：

您是否像这样将

MyFirebaseMessagingService

添加到

AndroidManifest.xml

文件中：

<service android:name=".firebase.messaging.MyFirebaseMessagingService">
      <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
      </intent-filter>
</service>

另外，要考虑到如果应用程序关闭（关闭或不活动），则不会调用该类，并且您需要从服务器正确发送消息数据。

可能尝试调试它-这可能有助于了解问题所在。在“MyFirebaseMessagingService”类中添加一个断点，看看它是否到达了那里。如果它到达了那里，我写“Log.I”（“通知”，“通知”）”并显示它。
