1.当收到通知时,会调用该方法,然后把通知Handler更新界面,所以可以在这个屏蔽通知的显示,可以通过参数设置,或者通过设置系统参数,这样可以通过配置参数就可以自由控制通知的显示,如下面,设置android_statusbar_visible参数,默认值为false,即不显示通知,if(!SystemProperties.getBoolean(android_statusbar_visible,false)) return;*/if (sbn ! null !onPluginNotificationPosted(sbn, rankingMap)) {mMainHandler.post(() - {processForRemoteInput(sbn.getNotification(), mContext);for (NotificationHandler handler : mNotificationHandlers) {handler.onNotificationPosted(sbn, rankingMap);}});}}Overridepublic void onNotificationRemoved(StatusBarNotification sbn, RankingMap rankingMap,int reason) {if (DEBUG) Log.d(TAG, onNotificationRemoved: sbn reason: reason);/*
2. 当通知被移除时,也需要坐下过滤if(!SystemProperties.getBoolean(android_statusbar_visible,false)) return;*/if (sbn ! null !onPluginNotificationRemoved(sbn, rankingMap)) {mMainHandler.post(() - {for (NotificationHandler handler : mNotificationHandlers) {handler.onNotificationRemoved(sbn, rankingMap, reason);}});}}Overridepublic void onNotificationRemoved(StatusBarNotification sbn, RankingMap rankingMap) {onNotificationRemoved(sbn, rankingMap, UNDEFINED_DISMISS_REASON);}Overridepublic void onNotificationRankingUpdate(final RankingMap rankingMap) {if (DEBUG) Log.d(TAG, onRankingUpdate);/*
3.这里是更新通知在通知列表上的排列,通知也需要坐下过滤if(!SystemProperties.getBoolean(android_statusbar_visible,false)) return;*/if (rankingMap ! null) {RankingMap r onPluginRankingUpdate(rankingMap);mMainHandler.post(() - {for (NotificationHandler handler : mNotificationHandlers) {handler.onNotificationRankingUpdate(r);}});}}......
