Android Notification在应用程序启动时触发

我正在尝试让我的每日通知服务正常工作，但我遇到了问题。

我应该只在将来的某个特定时间收到通知，但我注意到了

if (time_that_i_set_for_notification < current_time_of_the_day) notification triggers at the boot of my app 

这是错误的，因为在这种情况下，通知应该仅在第二天触发，而不是在我启动应用程序的瞬间。

这是我试图让事情奏效的尝试：

我在我的MainActivity，onCreate（）方法中调用它 ：

 private void scheduleNotification(int hour, int minute){ Intent notificationIntent = new Intent(this, NotificationReceiver.class); notificationIntent.putExtra("notifId", notifId); PendingIntent pendingIntent = PendingIntent.getBroadcast(this, notifId, notificationIntent, 0); // Set the alarm to start at approximately at a time DatePicker datePicker = new DatePicker(this); Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(System.currentTimeMillis()); calendar.set(Calendar.DAY_OF_MONTH, datePicker.getDayOfMonth()); if(calendar.getTime().compareTo(new Date()) < 0) calendar.add(Calendar.DAY_OF_MONTH, 1); calendar.set(Calendar.HOUR_OF_DAY, 12); calendar.set(Calendar.MINUTE, 12); AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE); // With setInexactRepeating(), you have to use one of the AlarmManager interval // constants--in this case, AlarmManager.INTERVAL_DAY. alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent); } 

我认为添加if(calendar.getTime().compareTo(new Date()) < 0) calendar.add(Calendar.DAY_OF_MONTH, 1); 我会达到我需要的结果。

谢谢你，祝你有美好的一天。

Answer 1

在调用setInexactRepeating之前，添加以下检查：

 if (calendar.getTimeInMillis() < System.currentTimeMillis()) calendar.setTimeInMillis(calendar.getTimeInMillis() + AlarmManager.INTERVAL_DAY); 

希望这可以帮助。

好吧那里有错误的检查，如果你改变它，你应该能够解决你的问题。

开始了：

 Intent notificationIntent = new Intent(this, NotificationReceiver.class); notificationIntent.putExtra("notifId", notifId); PendingIntent pendingIntent = PendingIntent.getBroadcast(this, notifId, notificationIntent, 0); // Set the alarm to start at approximately at a time DatePicker datePicker = new DatePicker(this); Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(System.currentTimeMillis()); calendar.set(Calendar.DAY_OF_MONTH, datePicker.getDayOfMonth()); //if(calendar.getTime().compareTo(new Date()) < 0) calendar.add(Calendar.DAY_OF_MONTH, 1); calendar.set(Calendar.HOUR_OF_DAY, 14); calendar.set(Calendar.MINUTE, 50); if (calendar.getTimeInMillis() < System.currentTimeMillis()) calendar.setTimeInMillis(calendar.getTimeInMillis() + AlarmManager.INTERVAL_DAY); AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE); // With setInexactRepeating(), you have to use one of the AlarmManager interval // constants--in this case, AlarmManager.INTERVAL_DAY. alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent); 

我评论了//if(calendar.getTime().compareTo(new Date()) < 0) calendar.add(Calendar.DAY_OF_MONTH, 1); 因为它应该是不必要的。

如果有效，请告诉我。

更新 ：您应该完全检查处理您的每日通知的服务是否消耗很高。 高耗电电池应用程序会打扰您的用户。
