Question

我正在进行闹钟应用，用户可以使用不同的响度和铃声添加多个闹钟。在广播接收器我想得到id（我在alarmpref活动设置id：

 public void setAlarm(Calendar calendar){
    Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), PendingIntent.FLAG_ONE_SHOT, intent, 0);
    AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 86400000, pendingIntent);
    Intent i = new Intent(this, AlarmReceiver.class);
    i.putExtra("id", 1);
    startActivity(i);
}

并使用它播放选定的铃声和响亮。谢谢

您需要按如下方式向Intent对象添加Extras：

 public void setAlarm(Calendar calendar){
    int requestCode=100;
    Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
    intent.putExtra("someid",123);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), requestCode, intent, PendingIntent.FLAG_ONE_SHOT);
    AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 86400000, pendingIntent);
}

并且也不需要写作：

Intent i = new Intent(this, AlarmReceiver.class);
    i.putExtra("id", 1);
    startActivity(i);

当达到警报的时间时，会自动启动AlarmReceiver。

如果我通过FLAG_ONE_SHOT添加id，如何获取待定意图的id？
