android alarmmanager多个警报，一个覆盖另一个？

Question

我已在帖子中搜索了我的问题的答案，但没有找到能解决我问题的任何东西。我正在尝试使用一个AlarmSettings类设置3种不同的警报。当我设置两个警报时，第二个警报优先于第一个警报，第一个永不熄灭。我认为这可能与我的未决意图有关……我真的是android新手，非常感谢您的帮助。这是我设置警报的代码：

public void setAlarm() {

        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        calendar.set(Calendar.HOUR_OF_DAY, timepicker.getCurrentHour());
        calendar.set(Calendar.MINUTE, timepicker.getCurrentMinute());
        calendar.set(Calendar.SECOND, 0);

        if (timepicker.getCurrentHour() < calendar.get(Calendar.HOUR_OF_DAY)) { //if the alarm hour is less than the current hour
            calendar.add(Calendar.DATE, 1);                                     //then add 24 hours (1 DATE or Day)                 
        }

        //Create the text that we want to set the TextView alarmtime to in Main
        StringBuilder sb = new StringBuilder();
        if (timepicker.getCurrentHour() > 12) {
            sb.append(timepicker.getCurrentHour() - 12);
        } else {
            sb.append(timepicker.getCurrentHour());
        }
        sb.append(":");
        sb.append(timepicker.getCurrentMinute());
        sb.append(" ");
        if (timepicker.getCurrentHour() > 12) {
            sb.append("pm");
        } else {
            sb.append("am");
        }

        if (((GlobalVariables)getApplication()).getCurrentAlarmBeingEdited() == 1) {
            ((GlobalVariables)getApplication()).setAlarm1Cal(calendar);
            Main.alarmTime1.setText(sb);

            Intent intent1 = new Intent(AlarmSettings.this, AlarmReceiver.class);
            intent1.putExtra("alarm_num", ((GlobalVariables)getApplication()).getCurrentAlarmBeingEdited());
            PendingIntent pendingIntent1 = PendingIntent.getActivity(getApplicationContext(), 0, intent1, PendingIntent.FLAG_ONE_SHOT);

            alarmmanager1.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent1);

        } else if (((GlobalVariables)getApplication()).getCurrentAlarmBeingEdited() == 2) {
            ((GlobalVariables)getApplication()).setAlarm2Cal(calendar);
            Main.alarmTime2.setText(sb);

            Intent intent2 = new Intent(AlarmSettings.this, AlarmReceiver.class);
            intent2.putExtra("alarm_num", ((GlobalVariables)getApplication()).getCurrentAlarmBeingEdited());
            PendingIntent pendingIntent2 = PendingIntent.getActivity(getApplicationContext(), 0, intent2, PendingIntent.FLAG_ONE_SHOT);

            alarmmanager2.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent2);

        } else if (((GlobalVariables)getApplication()).getCurrentAlarmBeingEdited() == 3) {
            ((GlobalVariables)getApplication()).setAlarm3Cal(calendar);
            Main.alarmTime3.setText(sb);

            Intent intent3 = new Intent(AlarmSettings.this, AlarmReceiver.class);
            intent3.putExtra("alarm_num", ((GlobalVariables)getApplication()).getCurrentAlarmBeingEdited());
            PendingIntent pendingIntent3 = PendingIntent.getActivity(getApplicationContext(), 0, intent3, PendingIntent.FLAG_ONE_SHOT);

            alarmmanager3.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent3);
        }

        finish();

        Toast.makeText(getApplicationContext(), "system time: " + System.currentTimeMillis() + "\n" + "picked time: " + calendar.getTimeInMillis(), Toast.LENGTH_LONG).show();      
    }

Answer 1

PendingIntent pendingIntent1 = PendingIntent.getActivity(getApplicationContext(), 0, intent1, PendingIntent.FLAG_ONE_SHOT);

将0属性更改为警报的ID，例如，您有三个警报，

用0,1,2重复上述代码。

这样，他们就不会互相覆盖。
