我有一些应用内通知在特定时间显示给用户，但在应用关闭时什么也没有显示。

I have some in-App notification to show to users at a specific time but nothing is shown when the App is closed.

设置警报：

Intent alarmIntent = new Intent(mMotherActivity, ReminderAlarmManager.class); if (ReminderNotificationType.CHANGE_LENS.equals(notificationType)) { alarmIntent.putExtra("NOTIFICATION_TYPE", "REMINDER"); } else { alarmIntent.putExtra("NOTIFICATION_TYPE", "ORDER"); } long scTime = alarmDate.getTime(); PendingIntent pendingIntent = PendingIntent.getBroadcast(mMotherActivity, 0, alarmIntent, 0); AlarmManager alarmManager = (AlarmManager) mMotherActivity.getSystemService(mMotherActivity.ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, scTime, pendingIntent);

广播接收器：

public class ReminderAlarmManager extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { String notificationType = intent.getStringExtra("NOTIFICATION_TYPE"); if(notificationType.equalsIgnoreCase("ORDER")) { Intent i = new Intent(context, OrderReminderNotificationService.class); context.startService(i); } else if(notificationType.equalsIgnoreCase("REMINDER")) { Intent i = new Intent(context, ReminderNotificationService.class); context.startService(i); } } }

因此，涉及到scTime ，即使该应用已关闭，我也想触发通知。因此，我通过PendingIntent调用服务，如下所示：

So when it comes to scTime, even if the App is closed, I would like to trigger a notification. So I'm calling a service by the PendingIntent, as follows:

public class OrderReminderNotificationService extends IntentService { public OrderReminderNotificationService(String name) { super(name); } @Override protected void onHandleIntent(Intent intent) { String ns = Context.NOTIFICATION_SERVICE; NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); Context context = getApplicationContext(); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder( context); Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); mBuilder.setContentTitle("Notification"); mBuilder.setContentText(context.getString(R.string.renewOrderNotificationMsg)); mBuilder.setSmallIcon(R.mipmap.ic_launcher); mBuilder.setSound(uri); mBuilder.setAutoCancel(true); Intent notificationIntent = new Intent(this, LoginActivity.class); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); mBuilder.setContentIntent(contentIntent); mNotificationManager.notify(2, mBuilder.build()); }

清单中与以下内容有关的部分：

The part in the manifest concerning that:

<receiver android:name="company.utils.ReminderAlarmManager"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter> </receiver>

但是什么都没有显示……我在做什么错？

But nothing shows up... What am I doing wrong ?

推荐答案

您的 AndroidManifest.xml 应该是这样的：

<receiver android:name=".ReminderAlarmManager"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter> </receiver> <service android:name=".OrderReminderNotificationService "/>
