SilenceReceiver silenceReceiver = new SilenceReceiver(); 
IntentFilter silenceFilter = new IntentFilter(SilenceReceiver.SILENCE_ALARM); 
registerReceiver(silenceReceiver, silenceFilter); 

AwakeReceiver awakeReceiver = new AwakeReceiver(); 
IntentFilter awakeFilter = new IntentFilter(AwakeReceiver.WAKE_ALARM); 
registerReceiver(awakeReceiver, awakeFilter); 

GregorianCalendar sleepCalendar = new GregorianCalendar(); 
sleepCalendar.set(Calendar.SECOND, sleepCalendar.get(Calendar.SECOND)+5); 
long triggerTime = sleepCalendar.getTimeInMillis(); 

GregorianCalendar awakeCalendar = new GregorianCalendar(); 
awakeCalendar.set(Calendar.SECOND, awakeCalendar.get(Calendar.SECOND)+30); 
long awakeTime = awakeCalendar.getTimeInMillis(); 

AlarmManager alarm = (AlarmManager) this.getSystemService(Service.ALARM_SERVICE); 
PendingIntent sleepIntent = PendingIntent.getBroadcast(this, 0, new Intent(SilenceReceiver.SILENCE_ALARM), 0); 
alarm.set(AlarmManager.RTC_WAKEUP, triggerTime, sleepIntent); 
PendingIntent awakeIntent = PendingIntent.getBroadcast(this, 0, new Intent(AwakeReceiver.WAKE_ALARM), 0); 
alarm.set(AlarmManager.RTC_WAKEUP, awakeTime, awakeIntent); 

問題是如果任務被殺死,我的AwakeReceiver永遠不會觸發。我能做些什麼嗎?任務中止後的AlarmManager

在清單中而不是在代碼中註冊廣播接收者的意圖過濾器。

謝謝。有沒有辦法在代碼中這樣做,以便我可以動態註冊/取消註冊它們?或者是否註冊了未使用的接收器而不對電池徵稅? – user123321

它爲什麼不同? (我知道它的確如此,但爲什麼/如何?)在清單中註冊時是否有另一種上下文?如果您在清單中註冊,爲什麼無法註銷代碼? 更重要的是,如果您必須註冊一個像ACTION_SCREEN_OFF這樣的操作,那麼必須在代碼中完成操作,您該怎麼辦?你怎麼能註冊它的行爲就像它在清單中註冊一樣? – IBoS
