【问题描述】:
我对@987654329@ 有疑问,如果我在应用程序在屏幕上运行时发送通知,通知会正确显示如下:
如果我在应用程序在后台运行时发送通知,通知显示如下:
这是我的FirebaseMessagingService 课程
public class AppFirebaseMessagingService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
sendNotification(remoteMessage);
}
private void sendNotification(RemoteMessage remoteMessage) {
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
int icon = Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP ? R.drawable.ic_video_label_white_24dp: R.drawable.ic_launcher;
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
notificationBuilder.setWhen(System.currentTimeMillis());
notificationBuilder.setColor(ContextCompat.getColor(this, R.color.colorPrimary));
notificationBuilder.setSmallIcon(icon);
notificationBuilder.setContentTitle(remoteMessage.getNotification().getTitle());
notificationBuilder.setContentText(remoteMessage.getNotification().getBody());
notificationBuilder.setAutoCancel(true);
notificationBuilder.setSound(defaultSoundUri);
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
Intent resultIntent = new Intent(this, MainActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(resultIntent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);
notificationBuilder.setContentIntent(pendingIntent);
notificationBuilder.setPriority(Notification.PRIORITY_HIGH);
}
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}
为什么会这样?
