Question

我必须在早上5:30触发本地通知，这是有效的。但问题是每当我打开我的应用程序时，通知也会被触发。这是我MainActivity中的代码：

在onCreate()的{{1}}中：

MainActivity

这是我的alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); Intent alarmIntent = new Intent(this, MyStartServiceReceiver.class); PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 100, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT); Calendar calendar = Calendar.getInstance(); calendar.set(Calendar.HOUR_OF_DAY, 5); calendar.set(Calendar.MINUTE, 5); calendar.set(Calendar.SECOND, 0); calendar.set(Calendar.AM_PM, Calendar.AM); alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);：

MyStartServiceReceiver

为什么每次打开我的应用程序时都会触发它？

Answer 1

因为你创造了

Calendar.getInstance()

例如在上午9点，但是在过去的时间上午5:30设定。所以当你使用

时

alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

它已经发生了。

您可以使用此

if(calendar.getTimeInMillis() < System.currentTimeMillis()) {
    calendar.add(Calendar.DAY_OF_MONTH, 1);
}

Answer 2

您正在设置闹钟当前日期上午5:05，如果已经通过警报将立即触发。要阻止它，请这样做。

AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
        Intent alarmIntent = new Intent(this, MyStartServiceReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 100, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, 5);
        calendar.set(Calendar.MINUTE, 5);
        calendar.set(Calendar.SECOND, 0);
        calendar.set(Calendar.AM_PM, Calendar.AM);
        if (System.currentTimeMillis() > calendar.getTimeInMillis()) {
            calendar.add(Calendar.DAY_OF_MONTH, 1);
        }
        alarmManager.cancel(pendingIntent);
        alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

我们在这里做的是，如果时间已经过去，我们将日期添加+1，这样它将从下一个日期开始，我们将取消之前的设置警报。

试试这个

alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    Intent alarmIntent = new Intent(this, MyStartServiceReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 100, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.HOUR_OF_DAY, 5);
    calendar.set(Calendar.MINUTE, 30);
    calendar.set(Calendar.SECOND, 0);
    if(calendar.getTime().after(new Date())){
    calendar.set(Calendar.Date,1);
    }
    alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
