[英]How to automatic enable/disable push notification for certain time
I'm new at using an alarm service for Android.我是使用 Android 警报服务的新手。 I want to create a medication reminder which is the medication information and number of repeated notification per day as the input data.我想创建一个用药提醒,它是用药信息和每天重复通知的次数作为输入数据。 However, I only want to enable the notification between 7 AM and 7 PM.但是,我只想在早上 7 点到晚上 7 点之间启用通知。 So, the apps will notify within that time only and also the apps will start to notify at 7 AM.因此,应用程序将仅在该时间内通知,并且应用程序将在上午 7 点开始通知。
Example: If the user wants to repeat the notification from the apps 3 times per day, then every 4 hours the apps will notify them to take the medicine (12 hours / 3 times = 4 hours).示例:如果用户想每天重复 3 次应用程序的通知,则应用程序将每 4 小时通知他们吃药(12 小时 / 3 次 = 4 小时)。
I have tried using the while loop, however it somehow didn't worked as I expected where if the condition is true, then it will keep on notify even though it's not the time yet (this happened to my code).我试过使用 while 循环,但是它在某种程度上没有按我预期的那样工作,如果条件为真,那么它会继续通知,即使现在还不是时候(这发生在我的代码上)。
So, here what I tried to do:所以,在这里我试图做的是:
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 7);
while(calendar.get(Calendar.HOUR_OF_DAY) >= 0) {
while (calendar.get(Calendar.HOUR_OF_DAY) >= 7 && calendar.get(Calendar.HOUR_OF_DAY) <= 19) {
// the process here
}
calendar.add(Calendar.HOUR_OF_DAY, 1);
}
I'm sorry if my code is lacking in many ways.如果我的代码在很多方面都缺乏,我很抱歉。 But, I really hope that you guys can help me or share with me any other possible solution.但是,我真的希望你们能帮助我或与我分享任何其他可能的解决方案。 Thank you.谢谢你。
You are setting the calendar hour incorrectly.您设置的日历时间不正确。
Replace代替
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 7);
while(calendar.get(Calendar.HOUR_OF_DAY) >= 0) {
while (calendar.get(Calendar.HOUR_OF_DAY) >= 7 && calendar.get(Calendar.HOUR_OF_DAY) <= 19) {
// the process here
}
calendar.add(Calendar.HOUR_OF_DAY, 1);
}
With和
Calendar cc = Calendar.getInstance();
int mHour = cc.get(Calendar.HOUR_OF_DAY);
if (mHour >= 7 && mHour <= 19) {
// the process here
}
