AlarmManager没反应，求指教

主体：

am = (AlarmManager) getSystemService(Service.ALARM_SERVICE);
Intent intent = new Intent(this,MyAlarmBroadCast.class);

PendingIntent pi = PendingIntent.getActivity(this, 0, intent, 0);

am.set(AlarmManager.RTC_WAKEUP, 10*1000, pi);

接收器：

public class MyAlarmBroadCast extends BroadcastReceiver{
    @Override  
    public void onReceive(Context context, Intent intent) {  
    Toast.makeText(context, "闹钟提示：时间到！", Toast.LENGTH_LONG).show();  
    }      
}

mainifest.xml
<receiver android:name=".MyAlarmBroadCast"> <intent-filter> <action android:name="com.example.energyup.MyAlarmBroadCast" /> </intent-filter> </receiver>

am.set(AlarmManager.RTC_WAKEUP, 10*1000, pi);

的第二个参数的理解有问题,这里传入的时唤醒准确时间,并不是间隔,按你的需求,应该是

am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+10*1000, pi);

看看文档中对RTC时间的解释
