Android反复闹钟(每天)的实现

/**
* Demo描写叙述:
* 反复闹钟的实现
*
* 注意事项:
* 1 由于我们是要实现的两个闹钟每天早八点和晚八点,它们是反复的.
*   所以在PendingIntent.getBroadcast()非常easy出错.导致早八点
*   的闹钟无效.主要原因是由于该方法的第四个參数引起的.
*   解决的方法:为BroadcastReceiver设置两个action,在生成Intent
*   的时候採用了不同的action,从而让两个闹钟都起作用.
*   假设有更好的方式请留言指出,多谢.
* 2 在calendar.set(Calendar.HOUR_OF_DAY, 8)方法的第二个參数
*   表示小时,请依照24小时制式填写.不用管此时设备採用什么时间
*   制式(12小时或24小时)
*
* 參考资料:
