关闭 Heads Up 通知并创建一个普通通知

Question

我正在使用此代码创建提醒通知。

private static void showNotificationNew(final Context context,final String title,final String message,final Intent intent, final int notificationId, final boolean isHeaderNotification) {
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context.getApplicationContext())
            .setSmallIcon(R.drawable.prime_builder_icon)
            .setPriority(Notification.PRIORITY_DEFAULT)
            .setCategory(Notification.CATEGORY_MESSAGE)
            .setContentTitle(title)
            .setContentText(message)
            .setWhen(0)
            .setTicker(context.getString(R.string.app_name));

    PendingIntent fullScreenPendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
    notificationBuilder.setContentText(message);
    if(isHeaderNotification) {
        notificationBuilder.setFullScreenIntent(fullScreenPendingIntent, false);
    }

    notificationBuilder.setContentIntent(fullScreenPendingIntent);
    notificationBuilder.setAutoCancel(true);


    Notification notification = notificationBuilder.build();
    NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(notificationId, notification);
}

问题是，通知应该占据顶部屏幕的很大一部分以引起用户注意，但几秒钟后它应该消失并出现正常的通知。

但是这段代码不会那样做。通知会一直占据整个顶部屏幕，直到用户将其关闭。

我正在考虑在几秒钟后使用 Handler 创建另一个具有相同 ID 的普通通知，但我想知道是否有更好的方法来做到这一点。

跟随WhatsApp的一个例子，模拟我想要的行为。

问题是因为您使用了setFullScreenIntent:

An intent to launch instead of posting the notification to the status bar. Only for use with extremely high-priority notifications demanding the user's immediate attention, such as an incoming phone call or alarm clock that the user has explicitly set to a particular time. If this facility is used for something else, please give the user an option to turn it off and use a normal notification, as this can be extremely disruptive.

也如本 answer you should use setVibrate 中所述，使单挑工作正常进行。

这是工作单挑通知的示例：

private static void showNotificationNew(final Context context, final String title, final String message, final Intent intent, final int notificationId) {
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context.getApplicationContext())
            .setSmallIcon(R.drawable.small_icon)
            .setPriority(Notification.PRIORITY_HIGH)
            .setContentTitle(title)
            .setContentText(message)
            .setVibrate(new long[0])
            .setContentIntent(pendingIntent)
            .setAutoCancel(true);

    NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(notificationId, notificationBuilder.build());
}
