AlarmManager打开一个活动

Question

在我的应用程序中，我使用以下代码为每周警报启动一项活动：

Manifest.xml：

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<receiver
    android:name=".utils.AlarmReceiver"
    android:enabled="true">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

设置闹钟的类有以下代码：

Intent alarmIntent = new Intent(getActivity(), AlarmReceiver.class);
alarmIntent.putExtra(Constants.HOME_FRAGMENT.CHANNEL_NAME, channelName);
pendingIntent = PendingIntent.getBroadcast(getActivity(), Integer.parseInt(id), alarmIntent, 0);
manager.set(AlarmManager.ELAPSED_REALTIME, calendar.getTimeInMillis(), pendingIntent);
// manager.setRepeating(AlarmManager.ELAPSED_REALTIME, calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY*7 , pendingIntent);

接收器类是

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        String channelName = intent.getStringExtra(Constants.HOME_FRAGMENT.CHANNEL_NAME);
        Intent i = new Intent(context, AlarmLiveNowActivity.class);
        i.putExtra(Constants.HOME_FRAGMENT.CHANNEL_NAME, channelName);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_NO_HISTORY);
        context.startActivity(i);
    }
}

我的问题是，AlarmLiveNowActivity在设备启动时启动。我不想要这个。它应该在设置警报时启动。我尝试了RTC，RTC_WAKE_UP等所有的ManagerTypes。我也尝试过使用setRepeating报警。但是，在设备启动后，Activity仍会亮起并闪耀！
