如何在我的应用中隐藏持久通知？

目前我的通知也在锁屏中显示，但我不想。我只想在向下滑动通知菜单时显示通知。

我知道这是可能的，因为我有一个名为@Override public int onStartCommand(Intent intent, int _flags, int _startId) { Intent notificationIntent = new Intent(this, MainActivity.class); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); noti = new Notification.Builder(getApplicationContext()) .setContentTitle("Title") .setContentText("Subtitle") .setSmallIcon(R.mipmap.ic_launcher) .setContentIntent(contentIntent) .build(); startForeground(1234, noti); mLocalBroadcastManager.sendBroadcast(new Intent(SERVICE_STARTED)); return Service.START_STICKY; }的应用程序，它正是这样做的。（TouchWiz Android 5.0.1）

这是我的通知代码（它在服务中）：

 <div class="follow">
        {% if followsId == null %}
            <div id="followUser"  data-userId="{{ profileUserData.id }}" data-currentUserId="{{ loggedUserData.id }}" data-action="follow">
                Follow
            </div>
        {% else %}
            <div id="unFollowUser" data-followsId="{{ followsId }}" data-action="unFollow">
                Unfollow
            </div>
        {% endif %}
        </div>

使用setVisibility(NotificationCompat.VISIBILITY_SECRET)＆amp; setPriority(Notification.PRIORITY_MIN)：

mNotification = new Notification.Builder(getApplicationContext())
        .setContentTitle("Title")
        .setContentText("Subtitle")
        .setSmallIcon(R.mipmap.ic_launcher)
        .setContentIntent(contentIntent)
        .setOngoing(true)
        .setVisibility(NotificationCompat.VISIBILITY_SECRET)
        .setPriority(Notification.PRIORITY_MIN)
        .build();

VISIBILITY_SECRET：

通知可见性：请勿在安全锁屏上显示此通知的任何部分。

PRIORITY_MIN：

最低优先级;除特殊情况外，这些项目可能不会向用户显示，例如详细的通知日志。

如果您仍想在状态栏中显示图标，则没有选项，但您可以通过订阅USER_PRESENT＆amp;来构建简单的解决方法。 SCREEN_OFF事件：

收到SCREEN_OFF次活动时取消通知
收到USER_PRESENT

注册BroadcastReceiver＆amp;通知默认通知：

mNotificationmanager =
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

IntentFilter filter = new IntentFilter();
filter.addAction("android.intent.action.USER_PRESENT");
filter.addAction("android.intent.action.SCREEN_OFF");
registerReceiver(mBroadcastReceiver, filter);

Intent notificationIntent = new Intent(this, YourActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

mNotification = new Notification.Builder(getApplicationContext())
        .setContentTitle("Title")
        .setContentText("Subtitle")
        .setSmallIcon(R.mipmap.ic_launcher)
        .setContentIntent(contentIntent)
        .setOngoing(true)
        .build();
mNotificationmanager.notify(NOTIF_ID, mNotification);

在BroadcastReceiver取消SCREEN_OFF时，通知USER_PRESENT：

private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {

        Log.v("test", intent.getAction());

        if (intent.getAction().equals("android.intent.action.SCREEN_OFF")) {
            mNotificationmanager.cancel(NOTIF_ID);
        } else if (intent.getAction().equals("android.intent.action.USER_PRESENT")) {
            mNotificationmanager.notify(NOTIF_ID, mNotification);
        }

    }
};
