多次设置闹钟 - 编程之家

如何解决多次设置闹钟

我实施了一个警报，该警报在给定执行时间的情况下会显示推送通知。

在MainActivity的onCreate（）中，我调用以下方法：

protected void initAlarm() throws FileNotFoundException {

        long _alarm,alarm_time;
        Calendar today = Calendar.getInstance();

        SharedPreferences settings;
        settings = getSharedPreferences(getString(R.string.app_name),Context.MODE_PRIVATE);
        SharedPreferences.Editor edit = settings.edit();

        today.set(Calendar.HOUR_OF_DAY,16-(int)Math.floor(Math.random()*3+1));
        today.set(Calendar.MINUTE,(int)Math.floor(Math.random()*60+1););
        today.set(Calendar.SECOND,0);

        alarm_time=today.getTimeInMillis();

        Calendar rightNow = Calendar.getInstance();

        if (alarm_time <= rightNow.getTimeInMillis()){
            _alarm = alarm_time + (AlarmManager.INTERVAL_DAY + 1);
        } else {
            _alarm = alarm_time;
        }

        Utils.setAlarm(alarmID,_alarm,Principal.this);

        edit.putInt("alarmID",alarmID);
        edit.putLong("alarmTime",_alarm);
        edit.commit();

    }

一旦警报在静态类AlarmReceiver中执行。我将在4天内每小时重置一次。（alarm_time + 5 *（AlarmManager.INTERVAL_DAY + 1））

public static class AlarmReceiver extends broadcastReceiver {

@Override
public void onReceive(Context context,Intent intent) {

    Log.d("WALKIRIA"," ALARM RECEIVED!!!");

    ClienteTCP2 myATaskYW = new ClienteTCP2();
    myATaskYW.execute(context);

    SharedPreferences settings = context.getSharedPreferences(context.getString(R.string.app_name),context.MODE_PRIVATE);
    Calendar today = Calendar.getInstance();
    SharedPreferences.Editor edit = settings.edit();

    today.set(Calendar.HOUR_OF_DAY,16-(int)Math.floor(Math.random()*3+1));
    today.set(Calendar.MINUTE,(int)Math.floor(Math.random()*60+1);
    today.set(Calendar.SECOND,0);

    long alarm_time=today.getTimeInMillis();

    Utils.setAlarm(settings.getInt("alarmID",3),hora_alarma+4*(AlarmManager.INTERVAL_DAY + 1),context);
    edit.putLong("alarmTime",alarm_time+5*(AlarmManager.INTERVAL_DAY + 1));
    edit.commit();
}

}

我的问题如下：该应用已启动，并且在特定时间设置了闹钟。然后，在执行警报时，会在4天之内再次设置一个小时（在AlarmReceiver类中），以使其再次执行。如果在这4天之前的任何时候初始化了应用程序，则将执行initAlarm（）方法，因此将再次设置新的警报时间。 我有2个警报吗？
