MainActivity如下:

package cc.cc;

import java.util.Calendar;

import java.util.Locale;

import android.os.Bundle;

import android.app.Activity;

import android.app.AlarmManager;

import android.app.PendingIntent;

import android.content.Context;

import android.content.Intent;

/**

* Demo描述:

* 重复闹钟的实现

*

* 注意事项:

* 1 因为我们是要实现的两个闹钟每天早八点和晚八点,它们是重复的.

* 所以在PendingIntent.getBroadcast()很容易出错.导致早八点

* 的闹钟无效.主要原因是因为该方法的第四个参数引起的.

* 解决办法:为BroadcastReceiver设置两个action,在生成Intent

* 的时候采用了不同的action,从而让两个闹钟都起作用.

* 如果有更好的方式请留言指出,多谢.

* 2 在calendar.set(Calendar.HOUR_OF_DAY, 8)方法的第二个参数

* 表示小时,请按照24小时制式填写.不用管此时设备采用什么时间

* 制式(12小时或24小时)

*
