Question

我正在拼命尝试向我的应用程序添加通知功能，使通知LED闪烁。在我所有的尝试之后没有任何作用......

这是我的代码：

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    NotificationCompat.Builder notification = new NotificationCompat.Builder(this)
            .setLights(Color.BLUE, 200, 200)
            .setContentTitle(remoteMessage.getData().get("title"))
            .setContentText(remoteMessage.getData().get("body"))
            .setColor(getColor(R.color.buttonBlueInactive))
            .setSmallIcon(R.mipmap.ic_launcher);
    NotificationManagerCompat manager = NotificationManagerCompat.from(this);
    manager.notify(1, notification.build());
}

如果有人能提供帮助，我们将非常感激。

对于那些遇到同样问题的人，有解决方案：

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    NotificationCompat.Builder notification = new NotificationCompat.Builder(this)
            .setLights(Color.BLUE, 200, 200)
            // Add the line bellow
            .setDefaults(Notification.DEFAULT_VIBRATE | Notification.DEFAULT_SOUND | Notification.FLAG_SHOW_LIGHTS)
            .setContentTitle(remoteMessage.getData().get("title"))
            .setContentText(remoteMessage.getData().get("body"))
            .setColor(getColor(R.color.buttonBlueInactive))
            .setSmallIcon(R.mipmap.ic_launcher);
    NotificationManagerCompat manager = NotificationManagerCompat.from(this);
    manager.notify(1, notification.build());
}

如果我没错，你就错过了setDefaults()

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    NotificationCompat.Builder notification = new NotificationCompat.Builder(this)
            .setLights(Color.BLUE, 200, 200)
            .setDefaults(Notification.DEFAULT_VIBRATE | Notification.DEFAULT_SOUND | Notification.FLAG_SHOW_LIGHTS) // Add this line
            .setContentTitle(remoteMessage.getData().get("title"))
            .setContentText(remoteMessage.getData().get("body"))
            .setColor(getColor(R.color.buttonBlueInactive))
            .setSmallIcon(R.mipmap.ic_launcher);
    NotificationManagerCompat manager = NotificationManagerCompat.from(this);
    manager.notify(1, notification.build());
}

在上面的示例中，我添加了以下选项：

Notification.DEFAULT_VIBRATE | Notification.DEFAULT_SOUND | Notification.FLAG_SHOW_LIGHTS

您可能希望根据需要进行更改。更多信息：

如果上述示例不起作用，请尝试以下代码：

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);

    NotificationCompat.Builder notification = new NotificationCompat.Builder(this)
            .setLights(Color.BLUE, 200, 200)
            .setContentTitle(remoteMessage.getData().get("title"))
            .setContentText(remoteMessage.getData().get("body"))
            .setColor(getColor(R.color.buttonBlueInactive))
            .setSmallIcon(R.mipmap.ic_launcher);

    Notification builtNotification = notification.build();
    builtNotification.flags |= Notification.FLAG_SHOW_LIGHTS;

    NotificationManagerCompat manager = NotificationManagerCompat.from(this);
    manager.notify(1, builtNotification);
}
