AlarmManager intent=null

Question

下面是我用来尝试设置AlarmManager的代码：

feedingIntent = new Intent(this, FeedingAlarmReceiver.class);
    feedingPI = PendingIntent.getBroadcast(this, 0, feedingIntent, 0);
    feedingAM = (AlarmManager) getSystemService(ALARM_SERVICE);
    feedingAM.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + 60000, feedingPI);

我基本上想让feedingIntent在按下按钮一分钟后触发。当我在按下按钮后检查logcat时，它显示我的意图为空：

V/AlarmManager﹕ sending alarm PendingIntent{435f7ac8: PendingIntentRecord{435b8ed0 com.example.parentingreminders broadcastIntent}}, intent=null, type=ELAPSED_REALTIME_WAKEUP, count=1, when=959128249, repeateInterval=0

这是我第一次使用AlarmManager，我不确定我做错了什么。

提前感谢！

您需要在feedingIntent中设置相应的动作来触发接收方

feedingIntent.setAction(Intent.ACTION_XXXX);
