android - 如何使用报警管理器区分上午和下午的报警？

Question

我正在为约会提醒创建警报警报，因为我正在使用以下代码。代码运行良好，它向我显示警报警报，但唯一的问题是，它无法区分上午和下午的警报，假设我设置了警报7am 和当前 7pm 在设备中，然后我的警报对话框也会显示。我该如何管理上午和下午？我使用此链接作为引用

您没有处理上午/下午。只需将这些代码行...

int timeDifference=0; 
String ampm=splitampmtime[1]; 
if(ampm.matches("PM")){ 
timeDifference=12; 
} 

int splithour = timeDifference+Integer.parseInt(splitstrtime[0]); 
String[] splitsecond = splitstrtime[1].split(" ");
