完整的场景是我正在尝试根据用户选择的时间显示通知，因为我正在使用 TimePickerDialog、BroadcastReceiver 类和 Service 类，一切正常，通知也会在特定时间出现，但问题是每次通知出现时我打开和关闭应用程序。

Activity.java

Intent myIntent = new Intent(ReminderActivity.this, MyBreakfastReciver.class);
System.out.println("getting Breakfast Reminder");
pendingIntent = PendingIntent.getBroadcast(ReminderActivity.this, 0, myIntent,0);

Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());

//bTimePart1 and bTimePart2 is the time choosen by user through time picker
calendar.set(Calendar.HOUR_OF_DAY, bTimePart1 );
calendar.set(Calendar.MINUTE, bTimePart2);

AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

BroadcastReciever

public class MyBreakfastReciver extends BroadcastReceiver
{

    @Override
    public void onReceive(Context context, Intent intent)
    {
        Intent service1 = new Intent(context, MyBreakfastAlarmService.class);
        context.startService(service1);

    }

}

Reciever class

 private void showNotification(Context context) {
        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(context)
        .setSmallIcon(R.drawable.notificationlogo)
        .setContentTitle("DietGuru")
        .setAutoCancel(true)
        .setContentText("You haven't logged your BreakFast for today.")
        .setSubText("Would you like to do it now?");


        // Creates an explicit intent for an Activity in your app
        Intent resultIntent = new Intent(context, CalorieMainActivity.class);

        // The stack builder object will contain an artificial back stack for the
        // started Activity.
        // This ensures that navigating backward from the Activity leads out of
        // your application to the Home screen.
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
        // Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(CalorieMainActivity.class);

        // Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(resultIntent);


        resultPendingIntent =
                stackBuilder.getPendingIntent(
                        0,
                        PendingIntent.FLAG_CANCEL_CURRENT
                        );
        mBuilder.setContentIntent(resultPendingIntent);

        //mBuilder.setContentIntent(resultPendingIntent);
        mBuilder.setDefaults(Notification.DEFAULT_ALL);

        NotificationManager mNotificationManager =
                (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        // mId allows you to update the notification later on.

        mNotificationManager.notify(1, mBuilder.build());

    }

我只想在打开和关闭应用程序时停止通知。

最佳答案

如果您选择的时间早于您的当前时间，那么 Alaram 火灾事件因此尝试检查时间是否早于当前时间然后添加日期，以便在给定时间的第二天发生 Alaram 火灾事件，检查以下示例，并在上午 8 点发出火灾通知每一天:

 Calendar calendar = Calendar.getInstance();
 calendar.setTimeInMillis(System.currentTimeMillis());
 // Set the alarm's trigger to next day if set alAram after 8 a.m.
 if(calendar.get(Calendar.HOUR_OF_DAY)>8){
       calendar.add(Calendar.DAY_OF_MONTH,1);
 }
 // Set the alarm's trigger time to 8:00 a.m.
 calendar.set(Calendar.HOUR_OF_DAY, 8);
 calendar.set(Calendar.MINUTE,0);
 calendar.set(Calendar.SECOND,0);

关于android - 在特定时间向用户显示通知，但每次我关闭或打开我的应用程序时它都会出现？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30052614/
