Android：获取Alarm Manager的状态

Question

我正在设置这样的警报：

mgr.setRepeating(AlarmManager.ELAPSED_REALTIME,SystemClock.elapsedRealtime() + PERIOD,PERIOD, pi);

是否有办法让警报管理器运行。

Answer 1

您可以使用以下代码检查触发的待处理意图是否正在运行。

Intent checkIntent = new Intent(getApplicationContext(),MyScheduledReceiver.class);
alarmUp = (PendingIntent.getBroadcast(getBaseContext(), 0, checkIntent, PendingIntent.FLAG_NO_CREATE) != null);
