Android的AlarmManager在一个BroadcastReceiver [英] Android AlarmManager in a Broadcastreceiver

问题描述

我有braodcastreceiver，该广播接收机应设定闹钟。

I have braodcastreceiver, that broadcast receiver shall schedule an alarm.

通常我会做

AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE); 
am.set(AlarmManager.RTC, time,  myPendingIntent); 

的问题是，getSystemService不在广播接收器仅在一个Activty。如何将我在这里？

The problem is that getSystemService is not available in a Broadcast receiver only in an Activty. How would I do it here?

谢谢你，A。

AndyAndroid,

getSystemService（）是上下文的一部分。您将需要保存上下文您在的onReceive（）方法，像这样得到...

getSystemService() is part of the Context. You will need to save the Context you receive in your onReceive() method like so...

private Context mContext;

@Override
public void onReceive(Context c, Intent i) {
    mContext = c;
}

Then..where你叫 getSystemService（）你用...

AlarmManager am = (AlarmManager) mContext.getSystemService(mContext.ALARM_SERVICE);
