如何在我的应用程序关闭之前一直显示 Android 通知？
我已经为 Android 开发了一段时间，但这是我第一次尝试通知。我已经按照 Android SDK 教程中的说明进行了通知设置，但我不知道如何在应用程序关闭之前保持通知显示。我想禁用通知末尾的那个小减号。我不希望我的通知在用户单击它时消失。我认为会有一个通知标志...但我似乎无法弄清楚这一点。我正在 Android SDK 2.2 上进行开发。我知道这是一个简单的问题，如果这个答案已经在这里，我深表歉意......我无法准确找到我正在寻找的内容。
// Create notification manager
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
Notification notification = new Notification(R.drawable.ic_launcher, "Ready", System.currentTimeMillis());
Intent notificationIntent = new Intent(this, HomeActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
// Make a notification
notification.setLatestEventInfo(getApplicationContext(), "Ready", "Select to manage your settings", contentIntent);
mNotificationManager.notify(0, notification);
I've been developing for Android for awhile but this is my first shot at notifications. I've got my notification setup as described in the Android SDK tutorial, but I can't figure out how to keep the notification displayed until my app is closed. I want to disable that little minus sign at the end of the notification. I don't want my notification to disappear when a user clicks it. I would think there would be a notification flag... but I can't seem to figure this out. I'm developing on Android SDK 2.2. I know this is a simple question, and I apologize if this answer is already on here... I wasn't able to find exactly what I was looking for.

您需要FLAG_ONGOING_EVENT。如果 FLAG_NO_CLEAR 和 FLAG_AUTO_CANCEL 是默认值的一部分，还可以尝试删除它们。
You want FLAG_ONGOING_EVENT. Also try removing FLAG_NO_CLEAR and FLAG_AUTO_CANCEL if they are part of the defaults.
