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)

AlarmBroadcastReceiver如下:
package cc.cc;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class AlarmBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if ("testalarm0".equals(intent.getAction())) {
System.out.println("第一个闹钟");
}
if ("testalarm1".equals(intent.getAction())) {
System.out.println("第二个闹钟");
}
}
}
