意图杀死一项服务

Question

我正在尝试为具有按钮的服务发出前景通知，按下该按钮将结束服务。我已经创建了按钮，但我不知道如何使我的意图结束服务。

public Notification getNotification(String message) {
    Intent intent = new Intent(serviceContext, NotificationGenerator.class);
    PendingIntent pi = PendingIntent.getActivity(serviceContext, 0, intent, 0);
    NotificationCompat.Builder builder = new NotificationCompat.Builder(serviceContext)
            .setContentTitle(message)
            .setContentText(message)
            .setSmallIcon(R.drawable.icon)
            .setContentIntent(pi)
            .addAction(R.drawable.remove_button,"End Service", endService);
    Notification n = builder.build();
    n.defaults = Notification.DEFAULT_ALL;
    return n;
}

Intent endService = new Intent（）;
我应该将endService设置为什么？
