单挑持续通知不隐藏

Question

我需要无法从通知抽屉中取消的提示通知，因此我创建了提示持续通知：

NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(context)
                    .setSmallIcon(R.drawable.logo_notification)
                    .setContentTitle("Title")
                    .setPriority(NotificationCompat.PRIORITY_HIGH)
                    .setDefaults(Notification.DEFAULT_ALL)
                    .setGroup(KEY)
                    .setGroupSummary(true)
                    .setOngoing(true)
                    .setColor(context.getResources().getColor(R.color.tab_indicator_color));


    // Creates an explicit intent for an Activity in your app
    Intent resultIntent = new Intent(context, Activity.class);

    // The stack builder object will contain an artificial back stack for the
    // started Activity.
    // This ensures that navigating backward from the Activity leads out of
    // your application to the Home screen.
    TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
    // Adds the back stack for the Intent (but not the Intent itself)
    stackBuilder.addParentStack(WActivity.class);
    // Adds the Intent that starts the Activity to the top of the stack
    stackBuilder.addNextIntent(resultIntent);
    PendingIntent resultPendingIntent =
            stackBuilder.getPendingIntent(
                    0,
                    PendingIntent.FLAG_UPDATE_CURRENT
            );
    mBuilder.setContentIntent(resultPendingIntent);

    NotificationManager mNotificationManager =
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    Intent pIntent = new Intent(context, PService.class);
    pIntent.setAction("ACTION");
    PendingIntent piPause = PendingIntent.getService(context, NOTIFICATION_ID, pIntent, 0);
    mBuilder.addAction(icon, title, piPause);

    Intent sIntent = new Intent(context, SService.class);
    sIntent.setAction("ACTION");
    PendingIntent piDismiss = PendingIntent.getService(context, NOTIFICATION_ID, sIntent, 0);
    mBuilder.addAction(icon2, title2, piDismiss);

问题是通知显示在屏幕顶部后，它不会隐藏到通知抽屉。但如果通知不在进行中，它就会隐藏。我需要将隐藏到通知抽屉的提示通知。

Answer 1

AFAIK，通知需要设置以下属性才能显示为提示通知。

.setPriority(NotificationCompat.PRIORITY_HIGH)
.setDefaults(Notification.DEFAULT_ALL)

setOngoing() 表示通知正在进行中，用户无法隐藏。我相信这可能就是您的通知保持在顶部并且不隐藏的原因。删除setOngoing(true)，它应该工作。
