java - 停止特定时间间隔的警报

Question

我在我的应用程序中设置了每日闹钟。到目前为止一切都很好。但现在我想要的是警报在特定的时间间隔内保持沉默。我疯狂的警报活动每 30 分钟调用一次。现在例如，如果我将晚上 11 点设置为凌晨 4 点，则警报应在晚上 11 点至下午 4 点之间保持静音。代码如下：

Calendar currentTime = new GregorianCalendar();
        currentTime.set(Calendar.HOUR,Hour);// EXtra Added
        currentTime.set(Calendar.MINUTE,Minute);
        currentTime.set(Calendar.SECOND, Calendar.SECOND);
        currentTime.set(Calendar.DATE, Calendar.DATE);
        currentTime.set(Calendar.MONTH, Calendar.MONTH);


        Calendar start_time = new GregorianCalendar();
        start_time.set(Calendar.HOUR, sHour);// EXtra Added
        start_time.set(Calendar.MINUTE, sMinute);
    //  start_time.set(Calendar.SECOND, Calendar.SECOND);
    //  start_time.set(Calendar.DATE, Calendar.DATE);
    //  start_time.set(Calendar.MONTH, Calendar.MONTH);

        Calendar end_time = new GregorianCalendar();
        end_time.set(Calendar.HOUR, eHour);// EXtra Added
        end_time.set(Calendar.MINUTE, eMinute);
    //  end_time.set(Calendar.SECOND, Calendar.SECOND);
    //  end_time.set(Calendar.DATE, Calendar.DATE);
    //  end_time.set(Calendar.MONTH, Calendar.MONTH);



if(!SILENCE)
{

    fireAlarm(Hour, Minute);
}
else if((start_time.getTimeInMillis()<=System.currentTimeMillis())&& (System.currentTimeMillis()<=end_time.getTimeInMillis() ) )
{
    System.out.println("You Are in Silent Mode");
    SIlent",Toast.LENGTH_SHORT).show();

}else{
    fireAlarm(Hour,Minute);
}

所以给我一个我可以解决的解决方案。谢谢。
