重复闹铃5分钟

Question

我有一个警报应用程序会持续响铃直到我停止但是现在我希望警报响一段时间。帮我做一下：

public void onToggleClicked(View view) {
    if (((ToggleButton) view).isChecked()) {
        Log.d("MyActivity", "Alarm On");
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, alarmTimePicker.getCurrentHour());
        calendar.set(Calendar.MINUTE, alarmTimePicker.getCurrentMinute());
        Intent myIntent = new Intent(Alarm_activity.this, AlarmReceiver.class);
        pendingIntent = PendingIntent.getBroadcast(Alarm_activity.this, 0, myIntent, 0);
        int repeatSeconds = 5;
        alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
                repeatSeconds * 1000, pendingIntent);
        alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(), pendingIntent);
    } else {
        alarmManager.cancel(pendingIntent);
        setAlarmText("");
        Log.d("MyActivity", "Alarm Off");
    }
}

这是闹钟启动功能。
