Question

我正在开展项目，我们正在为每个相册更新显示通知。但是，只需点击一个通知，它就会从通知栏中删除所有通知。

我尝试了以下代码：

 private void handleNotification(NotificationModel notificationModel) {
    // display the notification in the notification bar
    int i=0;
    if(!TextUtils.isEmpty(notificationModel.getAlbum_id()))
        i=Integer.parseInt(notificationModel.getAlbum_id());

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

    //icon appears in device notification bar and right hand corner of notification
    builder.setSmallIcon(R.mipmap.ic_launcher);

    Intent intent=new Intent(this,MainActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
    intent.putExtra(MainActivity.BUNDLE_ALBUM_ID_KEY, notificationModel.getAlbum_id());
    intent.putExtra(MainActivity.BUNDLE_ALBUM_NAME_KEY, notificationModel.getAlbum_title());

    /*intent = new Intent(this, NotificationActivity.class);*/
    PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(),i,intent,PendingIntent.FLAG_UPDATE_CURRENT);
    // Set the intent that will fire when the user taps the notification.
    builder.setContentIntent(pendingIntent);
    /*builder.setAutoCancel(true);*/
    // Large icon appears on the left of the notification
    builder.setLargeIcon(BitmapFactory.decodeResource(getApplicationContext().getResources(), R.mipmap.ic_launcher));

    // Content title, which appears in large type at the top of the notification
    builder.setContentTitle(notificationModel.getTitle());
    builder.setContentText(notificationModel.getMessage());
    builder.setAutoCancel(true);
    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    Notification notification=builder.build();

    notification.defaults = Notification.DEFAULT_SOUND
            | Notification.DEFAULT_VIBRATE;
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    notificationManager.notify(i,notification);
}

我做错了什么？

每次可能出现问题时，请检查作为通知ID工作的“i”的值是否相同... 的这里

int i=0; if(!TextUtils.isEmpty(notificationModel.getAlbum_id())) i=Integer.parseInt(notificationModel.getAlbum_id());

请检查“i”的值，我认为在您使用以下代码的情况下它总是相同的

PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(),**i**,intent,PendingIntent.FLAG_UPDATE_CURRENT);

并且

notificationManager.notify(i,notification);

点击一个通知，删除所有通知
