系统会通过两个方法将通知上报给SystemUI的NotificationListener类：

@Override
public void onListenerConnected() {
    if (DEBUG) Log.d(TAG, "onListenerConnected");
    onPluginConnected();
    final StatusBarNotification[] notifications = getActiveNotifications();
    if (notifications == null) {
        Log.w(TAG, "onListenerConnected unable to get active notifications.");
        return;
    }
    final RankingMap currentRanking = getCurrentRanking();
    mPresenter.getHandler().post(() -> {
        for (StatusBarNotification sbn : notifications) {
            mEntryManager.addNotification(sbn, currentRanking);
        }
    });
}
 
@Override
public void onNotificationPosted(final StatusBarNotification sbn,
        final RankingMap rankingMap) {
    if (DEBUG) Log.d(TAG, "onNotificationPosted: " + sbn);
    if (sbn != null && !onPluginNotificationPosted(sbn, rankingMap)) {
        //......省略部分代码......
    }
}
