如何设置 onClick 通知（Firebase）[重复]

Question

我想在通知上设置 onclick 以转到我从后端获得的特定活动。（FireBase）。目前，当我单击通知时，它会打开应用程序启动器活动。

Answer 1

请检查这是 MyFirebaseMessagingService 文件，我在这里设置了 onclick 并打开不同的活动：-

• 这里在第一个“if (json instanceof JSONObject) {”条件下从通知中获得的 json 响应中获取响应，然后打开评论活动。

• 在“else”中收到简单的消息并显示在通知上并从启动画面重新启动应用程序。

  public class MyFirebaseMessagingService extends FirebaseMessagingService {
  
          private static final String TAG = "MyFirebaseMsgService";
          Context mContext;
  
          /**
           * Called when message is received.
           *
           * @param remoteMessage Object representing the message received from Firebase Cloud Messaging.
           */
          // [START receive_message]
          @Override
          public void onMessageReceived(RemoteMessage remoteMessage) {
              // TODO(developer): Handle FCM messages here.
  
              Log.d(TAG, "From: " + remoteMessage.getFrom());
              Log.d(TAG, "Notification Message getMessageId: " + remoteMessage.getMessageId());
              Log.d(TAG, "Notification Message getMessage: " + remoteMessage.getData().get("message"));
              Log.d(TAG, "Notification Message getAction: " + remoteMessage.getData().get("action"));
              Log.d(TAG, "Notification Message ImageURL: " + remoteMessage.getData().get("imageUrl"));
              Log.d(TAG, "Notification Message from: " + remoteMessage.getData().get("from"));
              Log.d(TAG, "Notification Message google.message_id " + remoteMessage.getData().get("google.message_id"));
              mContext = getApplicationContext();
  
              Log.d(TAG, "Message data payload: " + remoteMessage.getData());
              String msg = remoteMessage.getData().get("message");
              try {
                  sendNotification(msg);
              } catch (JSONException e) {
                  e.printStackTrace();
              }
          }
  
          private void sendNotification(String message) throws JSONException {
              String commenterFname = "", commenterLname = "", commenterProfileImage = "", userID = "", postID = "";
  
              Object json = new JSONTokener(message).nextValue();
              if (json instanceof JSONObject) {
                  try {
                      JSONObject msg = new JSONObject(message);
                      commenterFname = msg.getString(Constant.JSON_KEY.COM_FNAME);
                      commenterLname = msg.getString(Constant.JSON_KEY.COM_LNAME);
                      commenterProfileImage = msg.getString(Constant.JSON_KEY.COM_IMAGE);

希望对你有帮助。

如果您从后端发送{"notification":""} 数据，android 将自动在通知托盘中显示通知（仅当您集成了 FCM sdk 时）。

如果你想控制通知，不要从后端发送通知对象，只发送数据对象（如果你从firebase控制台发送通知进行测试，通知对象将默认存在）

现在onMessageReceived() 方法将在您发送没有通知对象的通知时执行

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        String data=remoteMessage.getData();
        //parse data and show notification
        showNotification(parsedMessageData);
    }

    private void sendNotification(String message) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.putExtra("showNotification", true);
        intent.putExtra("params", params);
        if (page != null && page.equals(VIEW_INDENT)) {
            intent.putExtra("page", HomeNavigationController.DISPLAY_INDENT_TAG);
        }else if(page != null && page.equals(PAYMENT_SUMMERY)){
            intent.putExtra("page", HomeNavigationController.DISPLAY_PAYMENT_SUMMERY_TAG);
            intent.putExtra("month",paymentParams.getMonth());
            intent.putExtra("year",paymentParams.getYear());
            intent.putExtra("slotId",paymentParams.getSlotId());
        }
        else {
            intent.putExtra("page", HomeNavigationController.PRODUCT_LIST_TAG);
        }

        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.farm_taaza_logo)
                .setContentTitle("Sample Notification")
                .setStyle(new NotificationCompat.BigTextStyle().bigText(message))
                .setContentText(message)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
    }

Main Activity 将使用作为 putExtra 传递的参数启动，然后您可以从那里根据参数路由到相应的 Activity。
