AIR API預設上就支援這個功能了。NativeApplication.nativeApplication.timeSinceLastUserInput值可以取得目前閒置的時間。 private function init():void{ NativeApplication.nativeApplication.idleThreshold = 10; // 設定閒置通知的秒數 NativeApplication.nativeApplication.addEventListener(Event.USER_IDLE , onUserIdle ) ; NativeApplication.nativeApplication.addEventListener(Event.USER_PRESENT , onUserIdle ) ; } private function onUserIdle( event:Event ):void{ if(event.type == Event.USER_IDLE){ // 閒置 }else if(event.type == Event.USER_IDLE){ // 回復使用 } } 可是似乎沒有提供方法可以立刻中斷或reset閒置時間，不管是重設idleThreshold或者removeListener都不行。 idleThreshold 是用來設定「閒置通知事件」的發出時間點，但不管有沒有註冊監聽的事件，timeSinceLastUserInput的值是永遠都啟動、並且持續計算的。

如題。
