单击按钮后，我试图将Arraylist中的数据添加到javaFx列表视图中，但是由于出现错误，因此由于某些原因它不起作用，它在调试消息屏幕中显示有数据，但未在列表视图中显示它们！
任何帮助将不胜感激！
MainController类：
public class MainController {
walletDAO dao = new walletDAO();
ArrayList<wallet> allwallets = new ArrayList<wallet>();
@FXML
private Label message;
private ListView<ArrayList<wallet>> list;
public void getTags(ActionEvent event) throws SQLException {
allwallets = dao.getWalletTag();
System.out.println(allwallets);
list.getItems().add(allwallets);
}
}
错误消息：
Retrieve all tags
SELECT Tag FROM wallets;
[rfid2, rfid3]
