我使用此类来显示从firebase控制台收到的通知我自己的UI(RemoteViews)。当应用程序处于前台时,这可以正常工作,但是当应用程序处于后台时,通知会以默认的设备样式显示。我应该怎么做才能在我自己的UI中显示通知,即使应用程序是前台还是后台?
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "Mehdi";
@Override
public void onMessageReceived(RemoteMessage remoteMessage)
{
super.onMessageReceived(remoteMessage);
if (remoteMessage.getNotification() != null)
{
RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.payam_notification_layout);
contentView.setTextViewText(R.id.payam,remoteMessage.getNotification().getBody());
String channelId = "Default";
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this,channelId)
.setSmallIcon(R.drawable.status_icon_delivered)
.setLargeIcon(BitmapFactory.decodeResource( getResources(), R.mipmap.icon))
.setSound(Uri.parse("android.resource://" + getApplicationContext().getPackageName() + "/" + R.raw.notification))
.setCustomBigContentView(contentView)
.setContentTitle(remoteMessage.getNotification().getTitle())
.setContentText(remoteMessage.getNotification().getBody())
.setAutoCancel(true);
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId, "Default channel", NotificationManager.IMPORTANCE_DEFAULT);
manager.createNotificationChannel(channel);
}
manager.notify(0, mBuilder.build());
}
}
}
注意:感谢您的回答正确,我可以通过此链接使用自己的用户界面发送通知,即使应用是在后台或前台: http://www.androiddeft.com/2017/11/18/push-notification-android-firebase-php/

实际上我们在发送通知时使用了两种有效载荷,
一个是通知有效负载,另一个是数据有效负载。 当您处于从firebase服务调用onMessageReceived的前台时,通知有效负载会自动管理通知,但是当您在Background中时他们不会调用onMessageReceived,
因此,出于解决方案的目的,只需在数据有效负载中发送数据并删除通知有效负载,这样您就可以在每个状态的onMessageReceived中获取通知,并且您可以管理其中的UI
检查以下示例
function sendFCMNotification($message,$id) {
$url = 'https://fcm.googleapis.com/fcm/send';
$fields = array (
'to' => $id,
'data' => array (
"body" => $message,
"title" => "Title Text"
)
);
$fields = json_encode ( $fields );
$headers = array (
'Authorization: key=' . "Legcy Key",
'Content-Type: application/json'
);
