android - setLatestEventInfo 无法解析

Question

我正在尝试在 api 级别 10 和以下是我的代码，但我收到语法错误 setLatestEventInfo 无法解决。我猜它与 API 级别有关

 public static void sendNotification(Context caller, Class<?> activityToLaunch, String title, String msg, int numberOfEvents, boolean sound, boolean flashLed, boolean vibrate, int iconID) {
    NotificationManager notifier = (NotificationManager) caller.getSystemService(Context.NOTIFICATION_SERVICE);

    final Notification notify = new Notification(iconID, "", System.currentTimeMillis());

    notify.icon = iconID;
    notify.tickerText = title;
    notify.when = System.currentTimeMillis();
    notify.number = numberOfEvents;
    notify.flags |= Notification.FLAG_AUTO_CANCEL;
    if (sound) notify.defaults |= Notification.DEFAULT_SOUND;

    if (flashLed) {
        // add lights
        notify.flags |= Notification.FLAG_SHOW_LIGHTS;
        notify.ledARGB = Color.BLUE;
        notify.ledOnMS = 500;
        notify.ledOffMS = 500;
    }

    if (vibrate) {
        notify.vibrate = new long[]{100, 200, 300};
    }

    Intent toLaunch = new Intent(caller, activityToLaunch);
    toLaunch.addFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
    toLaunch.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent intentBack = PendingIntent.getActivity(caller, notify.number, toLaunch, 0);
    notify.setLatestEventInfo(caller, title, msg, intentBack);
    notifier.notify(notify.number, notify);
    notify.number = notify.number + 1;
}

如果您的编译 SDK 版本设置为 api 23+，您将看到此问题。此方法已在 M (api 23) 中删除。

要从 api 4 开始通知，您可以使用 NotificationCompat.Builder这是在 Android Support Library 中添加的. Android Documentation有一个像样的例子:

 Notification noti = new Notification.Builder(mContext)
         .setContentTitle("New mail from " + sender.toString())
         .setContentText(subject)
         .setSmallIcon(R.drawable.new_mail)
         .setLargeIcon(aBitmap)
         .build();

如果需要支持旧的 api 版本，您可以将“Notification.Builder”替换为“NotificationCompat”。
