Question

我的应用会生成如下通知：

final Bundle intentExtras = intent.getExtras();
final String title = intentExtras.getString(Constants.EXTRA_TITLE);
final String body = intentExtras.getString(Constants.EXTRA_BODY);
final Integer notifID = intentExtras.getInt(Constants.EXTRA_ID);

// this pending intent will launch after notification is selected
Intent notificationIntent = new Intent(context, NotificationReceiverActivity.class);
notificationIntent.putExtras(intentExtras);// pass the extra data forward to NotificationReceiverActivity
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(context, notifID, notificationIntent, PendingIntent.FLAG_ONE_SHOT);

// build notification to show on the notification bar
try
{
    final String packagename = context.getPackageName();
    PackageInfo packageinfo = context.getApplicationContext().getPackageManager().getPackageInfo(packagename, 0);
    final int iconid = packageinfo.applicationInfo.icon;

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
            .setAutoCancel(false)
            .setContentIntent(pendingIntent)
            .setSmallIcon(iconid)
            .setContentTitle(title)
            .setContentText(body);

    // build notification and set alerts
    Notification notification = mBuilder.build();
    notification.defaults |= Notification.DEFAULT_ALL;

    // show notification
    NotificationManager notificationMgr = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    notificationMgr.notify(notifID, notification);
}
catch (android.content.pm.PackageManager.NameNotFoundException e)
{}

每个notifID都是唯一的！但是，如果应用显示两个或多个通知，并且用户选择其中一个，则会清除该应用的两个通知！

我尝试过使用setAutoCancel(false)或setAutoCancel(true)，但它并没有什么区别。

此外，无法拨打NotificationManager.cancel()或NotificationManager.cancelAll()

如果用户只选择其中一个应用后，如何阻止该应用清除该应用的所有通知？

进一步调查......

我发现启动应用后应用的通知消失了。但是，看不到.cancel（）或.cancelAll（）...... / confused

NotificationCompat.Builder正在创建在选择一个通知后取消的通知
