用javafx中的线程手动更新listview

我正在开发一个邮箱,我想让客户自动检查是否有新的电子邮件。我通过使用一个线程来实现这一点,该线程循环直到关闭客户机,如果看到列表中当前的电子邮件数量与服务器上的文件数量不同,那么它会重新加载数据并添加新的电子邮件。它是有效的,但是每次我在列表上得到更新时,我都会得到这个例外:

Exception in thread "Thread-5" java.lang.IllegalStateException: Not on FX application thread; currentThread = Thread-5

这是我的ListView控制器代码:

public class ListController {

@FXML
private ListView<Email> listView;
private DataModel model;
private int NoE;

public void initModel(DataModel model) throws IOException, ClassNotFoundException, ParseException {
    if (this.model != null) {
        throw new IllegalStateException("Model can only be initialized once");
    }
    this.model = model;

    model.loadData();

    listView.setItems(model.getEmailList());

    listView.getSelectionModel().selectedItemProperty().addListener((obs, oldSelection, newSelection)
            -> model.setCurrentEmail(newSelection));
    model.currentEmailProperty().addListener((obs, oldEmail, newEmail) -> {
        if (newEmail == null) {
            listView.getSelectionModel().clearSelection();
        } else {
            listView.getSelectionModel().select(newEmail);
        }
    });

    listView.setCellFactory(lv -> new ListCell<Email>() {
        @Override
        public void updateItem(Email mail, boolean empty) {
            super.updateItem(mail, empty);
            if (empty) {
                setText(null);
            } else if (mail != null) {
                setText(mail.getMittente());
            }
        }
    });

    NoE = model.getNumberOfEmail();
    new Thread() {
        @Override
        public void run() {
            while (true) {
                try {
                    int current = model.askNumbOfEmail();
                    if (NoE != current) {
                        NoE = current;
                        model.reLoadData();
                        listView.setItems(model.getEmailList());
                    }
                } catch (IOException ex) {
                    Thread.currentThread().interrupt();
                    return;
                } catch (ParseException ex) {
                    System.out.println("ParseException ERROR!");
                }
            }
        }
    }.start();
  }
}
