找不到如何在代码中编辑推送通知标题和内容 - Android Studio

Question

我购买了应用程序模板，但我无法在代码中找出更改推送通知标题和内容的位置（Firebase 作为消息提供者平台）。开发人员无法访问，我无法进一步处理项目。

例如，改为推送“您有新消息”我想要“您有一条新消息”；我搜索了整个代码但没有成功。

另外 - 有什么方法可以将推送通知翻译成多种语言？

编辑

源文件中没有与消息相关的 Firebase 扩展服务，仅与电话身份验证相关。

附加信息

让我解释一下消息的性质：有两个应用程序 - 司机和乘客：当乘客做某事时，例如 - 要求附近的司机，附近的所有司机都会收到推送消息 - 你有一个新的请求。此外，例如 - 付款时 - 乘客收到消息 - 付款已结算。看在上帝的份上，这个存储在哪里:)

Answer 1

尝试搜索扩展 FirebaseMessagingService 的类。这是所有 FCM 服务设置的地方。

编辑

这就是我在自己的应用中自定义通知的方式：

Intent intent = new Intent(this, BOBusinessHomePage.class);           
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);

Notification notification =
    new NotificationCompat.Builder(getApplicationContext(), "0")
    .setSmallIcon(R.drawable.business_icon)
    .setContentTitle("A client has posted a new review in your business page!")
    .setPriority(NotificationCompat.PRIORITY_DEFAULT)
    .setContentIntent(pendingIntent)
    .setAutoCancel(true)
    .build();
mNotificationManager.notify(0, notification);

尝试在您的项目中搜索“通知”或任何与上述类似的模板。

或者，尝试搜索名为onMessageReceived()的回调方法。

说明

默认情况下，您的应用在前台时不会显示它收到的任何 FCM 消息，因此当您发送消息时，无法保证您的用户会真正看到该消息。

要处理您的应用在前台收到的消息，您需要扩展 FirebaseMessagingService，覆盖 onMessageReceived 方法，然后使用 getNotification 或 getData 检索消息的内容，具体取决于您是否在工作带有数据或通知消息，或两者兼有。
