java - AlarmManager 在两个特定时间

Question

我在 9:00 和 21:00 有两个 AlarmManager，但只运行第二个闹钟。

    ////////9:00am/////////
    Intent aviso = new Intent(FijarAlerta.this,Servicio.class);
    PendingIntent pi = PendingIntent.getService(FijarAlerta.this, 0, aviso, PendingIntent.FLAG_UPDATE_CURRENT);
           //set the hour
    Calendar cal = Calendar.getInstance();
    cal.set(Calendar.HOUR_OF_DAY, 9);
    cal.set(Calendar.MINUTE, 0);
    cal.set(Calendar.SECOND, 0);
    AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
    am.setRepeating(AlarmManager.RTC_WAKEUP,cal.getTimeInMillis(),AlarmManager.INTERVAL_DAY,pi);

第二个闹钟

////////21:00pm//////////
    Intent avisopm = new Intent(FijarAlerta.this,Servicio.class);
    PendingIntent pipm = PendingIntent.getService(FijarAlerta.this, 0, avisopm, PendingIntent.FLAG_UPDATE_CURRENT);
                 //set the hour
    Calendar calpm = Calendar.getInstance();
    calpm.set(Calendar.HOUR_OF_DAY, 21);
    calpm.set(Calendar.MINUTE, 0);
    calpm.set(Calendar.SECOND, 0);
    AlarmManager ampm = (AlarmManager)getSystemService(ALARM_SERVICE);
    ampm.setRepeating(AlarmManager.RTC_WAKEUP,calpm.getTimeInMillis(),AlarmManager.INTERVAL_DAY,pipm);

Answer 1

调用 PendingIntent.getService() 的第二个参数在每种情况下都应该是不同的数字。例如:

PendingIntent pi = PendingIntent.getService(FijarAlerta.this, 111, aviso,       PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent pipm = PendingIntent.getService(FijarAlerta.this, 222, avisopm, PendingIntent.FLAG_UPDATE_CURRENT);

目前第二个pendingIntent刚刚覆盖第一个
