我在晚上 10:30 收到通知。但是当我的设备在晚上 10:30 关闭，然后在晚上 11:00 打开我的设备后，我没有收到待处理的通知。所以我不明白问题出在哪里。任何帮助将不胜感激。

这是我在创建 Activity 中的代码。

    Intent alarmIntent = new Intent(CH_Dashboard.this,  TimeAlarmEvening.class);

    PendingIntent pendingIntent = PendingIntent.getBroadcast(CH_Dashboard.this, 0, alarmIntent, 0);

    AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

    Calendar firingCal = Calendar.getInstance();
    Calendar currentCal = Calendar.getInstance();

    firingCal.set(Calendar.HOUR, 10);
    firingCal.set(Calendar.MINUTE, 30);
    firingCal.set(Calendar.SECOND, 0);
    firingCal.set(Calendar.AM_PM,Calendar.PM);

    long intendedTime = firingCal.getTimeInMillis();
    long currentTime = currentCal.getTimeInMillis();

    if(intendedTime >= currentTime)
    {
        manager.setRepeating(AlarmManager.RTC,
                intendedTime, AlarmManager.INTERVAL_DAY,
                pendingIntent);
    }
    else
    {
        firingCal.add(Calendar.DAY_OF_MONTH, 1);
        intendedTime = firingCal.getTimeInMillis();

        manager.setRepeating(AlarmManager.RTC,
                intendedTime, AlarmManager.INTERVAL_DAY,
                pendingIntent);
    }

我的接收器代码在这里，并在设备开启时成功收到通知。

        Intent notificationIntent = new Intent(context, CH_Dashboard.class);
        notificationIntent.putExtra("fromNotification","notify");
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
        stackBuilder.addParentStack(CH_Dashboard.class);
        stackBuilder.addNextIntent(notificationIntent);

        PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(context);

        builder.setAutoCancel(true);

        Notification notification = builder.setContentTitle("Demo App Notification")
                .setContentText("New Notification From Demo App..")
                .setTicker("New Message Alert!")
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentIntent(pendingIntent).build();

        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, notification);

这是我的启动接收器代码。

    if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED))
    {
     Intent alarmIntent = new Intent(context, TimeAlarmEvening.class);
     PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, 0);

    AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

    Calendar firingCal = Calendar.getInstance();
    Calendar currentCal = Calendar.getInstance();

    firingCal.set(Calendar.HOUR, 10);
    firingCal.set(Calendar.MINUTE, 30);
    firingCal.set(Calendar.SECOND, 0);
    firingCal.set(Calendar.AM_PM,Calendar.PM);

    long intendedTime = firingCal.getTimeInMillis();
    long currentTime = currentCal.getTimeInMillis();

    if(intendedTime >= currentTime)
    {
        manager.setInexactRepeating(AlarmManager.RTC,
                intendedTime, AlarmManager.INTERVAL_DAY,
                pendingIntent);
    }
    else
    {
        firingCal.add(Calendar.DAY_OF_MONTH, 1);
        intendedTime = firingCal.getTimeInMillis();

        manager.setInexactRepeating(AlarmManager.RTC,
                intendedTime, AlarmManager.INTERVAL_DAY,
                pendingIntent);
    }

  }

最后在 list 中我声明了接收者。

     <receiver
        android:name=".model.AutoStart"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>

    <receiver android:name=".TimeAlarmEvening">
        <intent-filter>
            <action android:name="android.media.action.DISPLAY_NOTIFICATION_EVENING" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>

最佳答案

那天我解决了，但忘了在这里回答。我对 list 文件进行了一些更改。只需删除 Intent 过滤器和作品中的默认行类别。

 <receiver
    android:name=".model.AutoStart"
    android:enabled="true"
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

<receiver android:name=".TimeAlarmEvening">
    <intent-filter>
        <action android:name="android.media.action.DISPLAY_NOTIFICATION_EVENING" />
    </intent-filter>
</receiver>
