尝试过滤从文本字段中搜索表格时遇到麻烦

Question

我的文本字段称为搜索

private void srch(){

    columnFname.setCellValueFactory(cellData -> cellData.getValue().FirstNameProperty());
    columnLname.setCellValueFactory(cellData -> cellData.getValue().LastNameProperty());

    FilteredList<CustomerDetails> filteredData = new FilteredList<>(data, p -> true);

    search.textProperty().addListener((observable, oldValue, newValue) -> {
        filteredData.setPredicate((Predicate<? super CustomerDetails>) (CustomerDetails csd) -> {
            // 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 (csd.getFirstName().toLowerCase().contains(lowerCaseFilter)) {
                return true; // Filter matches first name.
            } else if (csd.getLastName().toLowerCase().contains(lowerCaseFilter)) {
                return true; // Filter matches last name.
            }
            return false; // Does not match.
        });
    });
    // 3. Wrap the FilteredList in a SortedList.
    SortedList<CustomerDetails> sortedData = new SortedList<>(filteredData);

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

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

}
