Question

我这堂课有问题。我使用了fcm而我试图处理通知。我发送通知，然后我就回复了，但我不能改变任何东西，如果我删除了一些行，它仍然可以工作..另外，当我提出一些断点或当我想在Log中写一些东西时它不是工作。在Body中我发送了一些名字，我添加了ID。例如＆＃34; Nike45＆＃34;，在代码中我试图得到那个数字，我需要在Intent中额外添加它。但它不起作用..我在gradle和manifest中添加了行。

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    String title = remoteMessage.getNotification().getTitle();
    String message = remoteMessage.getNotification().getBody();
    final Pattern lastIntPattern = Pattern.compile("[^0-9]+([0-9]+)$");
    String input = message;

    if (matcher.find()) {
        String someNumberStr = matcher.group(1);
        lastNumberInt = Integer.parseInt(someNumberStr);

    message = message.replaceAll("\\d","");

    notificationManager.notify(0, notificationBuilder.build());

}

Answer 1

您的代码没问题，只是确保您发送消息有效负载而不仅仅是来自Firebase的通知，因为onMessageRecieved仅在有消息有效负载时触发，如果它是正常通知则永远不会触发

Answer 2

确保正确处理通知和数据有效负载，可能是您错过了数据有效负载。请尝试以下代码，

 @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        Log.e(TAG, "From: " + remoteMessage.getFrom());

        if (remoteMessage == null)
            return;

        // Check if message contains a notification payload.
        if (remoteMessage.getNotification() != null) {
            Log.e(TAG, "Notification Body: " + remoteMessage.getNotification().getBody());
            handleNotification(remoteMessage.getNotification().getBody());
        }

        // Check if message contains a data payload.
        if (remoteMessage.getData().size() > 0) {
            Log.e(TAG, "Data Payload: " + remoteMessage.getData().toString());

            try {
                JSONObject json = new JSONObject(remoteMessage.getData().toString());
                handleDataMessage(json);
            } catch (Exception e) {
                Log.e(TAG, "Exception: " + e.getMessage());
            }
        }
    }
