tableview过滤器上的javafx错误

我想使用textfield过滤tableview中的数据,但我不知道为什么会出现错误

控制器 我的代码:

    @FXML
private TextField search;
private ObservableList<person1> masterData = FXCollections.observableArrayList();

    @Override
    public void initialize(URL url, ResourceBundle rb) {




         FilteredList<person1> filteredData = new FilteredList<>(masterData, p -> true);

              search.textProperty().addListener((observable, oldValue, newValue) -> {
            filteredData.setPredicate(person -> {
                // If filter text is empty, display all persons.
                if (newValue == null || newValue.isEmpty()) {
                    return true;
                }

                // Compare first name and last name of every person with filter text.
                String lowerCaseFilter = newValue.toLowerCase();

                if (person.getFirstName().toLowerCase().indexOf(lowerCaseFilter) != -1) {
                    return true; // Filter matches first name.
                }  
                return false; // Does not match.
            });


        });
                   SortedList<person1> sortedData = new SortedList<>(filteredData);

        // 4. Bind the SortedList comparator to the TableView comparator.
        sortedData.comparatorProperty().bind(table3.comparatorProperty());

        // 5. Add sorted (and filtered) data to the table.
       table3.setItems(sortedData);

         studlist();

    }    


    public void studlist(){
    String s=(String) com2.getSelectionModel().getSelectedItem();
    String s1=(String) com3.getSelectionModel().getSelectedItem();
    String cls="";
    String sec="";
    if(!(s==null))cls="where currentclass='"+s+"'";
     if(!(s1==null))sec="  and currentsec='"+s1+"'";
      try{
       Class.forName("com.mysql.jdbc.Driver");
            Connection con=(Connection)DriverManager.getConnection("jdbc:mysql://localhost:3306/schoolmanagement","root","root");
            String sql="Select * from student_information "+s+""+s1;
           Statement stm=(Statement) con.createStatement();
ResultSet rs=stm.executeQuery(sql);
while(rs.next()){
 table3.getItems().add(new person1(rs.getString(3), rs.getString(2)));

} }
        catch (ClassNotFoundException | SQLException e) {

        }

    }
当我认为数据在表中添加时,

出现错误 错误:

我不知道为什么我会收到此错误,请帮助我。

谢谢。

1 个答案:

答案 0 :(得分:1)

您可能正在尝试添加到无法修改的排序列表中。尝试使用FXCollections.sort(),它会对列表进行排序并保持可修改状态。

javadoc

我不确定FilteredList是否也可修改,因此您可能仍有问题。我认为你应该添加到masterData。

编辑:我只花了5分钟进行测试,你无法添加到过滤或排序列表。添加到基础列表(masterData)

时,过滤工作正常
