警报系统--时间段计算
//------------------2019-10-24
居然看不懂了，估计使用系统时钟AlarmManager,
在工作时间段内使用Repeating方式每8分钟执行一次，而是休息时段
着使用定时唤醒方式跳过，即比分在08:00使用RTC_WAKEUP唤醒
//------------------End 2019-10-24---------
允许用户指定工作时间段，只有在指定的时间段内警报才会被触发
时段记录结构:
/**
* 说明表示格式与范围是:[00,00 - 24,00]
* 分钟部分范围是[0-59]
* 8,50 表示8点50
* 最小单位是分钟，由0,1,2,3,....1439
* 个指定时间段不能相交,开始时间点与结束时间点必需唯一
* includeTime内各时间段必须按小到大排序
*/
private void initIncludeTime() {
includeTime=new ArrayList<AlarmSetting.HourSegment>();
includeTime.add(new HourSegment(7,0,10,30)); //7:00 - 10:30
includeTime.add(new HourSegment(13,30, 16,30));//13:30 - 16:30
includeTime.add(new HourSegment(18,30, 20,30));//18:30 - 20:30
}
排除时段列表计算:
//计算排除时间列表
int bPoint=0;
List<HourSegment> excludes=new ArrayList<AlarmSetting.HourSegment>();
for (HourSegment s : getIncludeTime()) {
int sBIndex=getIndex(s.beginHour,s.beginMinute);
int sEIndex=getIndex(s.endHour,s.endMinute);
if(sBIndex > bPoint){
excludes.add(new HourSegment(getMoment(bPoint), getMoment(sBIndex-1)));
}
bPoint=sEIndex + 1;
if(bPoint>1439)break;
}
if(bPoint<=1439){
excludes.add(new HourSegment(getMoment(bPoint), getMoment(1439)));
}
