将意图额外数据传递给Android广播接收器

Question

我创建了一个AlarmReceiver类，用作闹钟的广播接收器。问题是我需要从设置闹钟的类中发送一些值到广播接收器类中。

setAlarmManager.java

     Intent i = new Intent(mContext, AlarmReceiver.class);
     i.putExtra(KEY_ROWID, (long)taskId); 
     PendingIntent pi = PendingIntent.getBroadcast(mContext,taskId_int,i,PendingIntent.FLAG_ONE_SHOT); 
     mAlarmManager.set(AlarmManager.RTC_WAKEUP, when.getTimeInMillis(), pi);

我需要在AlarmReceiver类中从Intent中获取KEY_ROWID。我该怎么做？下面是AlarmReceiver类的代码：

public class AlarmReceiver extends BroadcastReceiver {
          public static final String ALARM_ALERT_ACTION ="com.android.alarmclock.ALARM_ALERT";
          public static final String ALARM_INTENT_EXTRA = "intent.extra.alarm";

     @Override
      public void onReceive(Context context, Intent intent) {

             //Here I need the values from intent using bundle or anything...

    }
}

你可以使用：

public class AlarmReceiver extends BroadcastReceiver {
          public static final String ALARM_ALERT_ACTION ="com.android.alarmclock.ALARM_ALERT";
          public static final String ALARM_INTENT_EXTRA = "intent.extra.alarm";

     @Override
      public void onReceive(Context context, Intent intent) {

             String keyid = intent.getStringExtra("KEY_ROWID");
    }
}
