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。
推荐答案
AndyAndroid，
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);
