Question

我有一个表格内的表格我有复选框我需要的东西，当我选择行来选中此复选框和其他复选框取消选择我解决它通过在表视图上有监听器并迭代列表项并设置选中的false并且只选择的行为true但我遇到的问题是当我调用ObservableList.setall（...）时我的代码后出现了这些异常

AccountingFilesTable.getSelectionModel().selectedItemProperty().addListener(
            (observable, oldValue, newValue) -> showAccountingFilesDetails(newValue));
private void showAccountingFilesDetails(AccountingFiles newValue) {
AccountingFiles curraccfile = AccountingFilesTable.getSelectionModel().getSelectedItem();
   AccountingFilesTable.getSelectionModel().clearSelection();

    System.out.println(curraccfile.getAccountingFilesName());

    for (AccountingFiles af : accountingData) {

        mainEm.getTransaction().begin();
        af.setAccountingFilesActiveStatus(false);
        mainEm.getTransaction().commit();
        //accountingData.set(accountingData.indexOf(af), af);
        System.out.println("in looooooooooooop");
    }
    mainEm.getTransaction().begin();
    curraccfile.setAccountingFilesActiveStatus(true);
    mainEm.getTransaction().commit();
    List<AccountingFiles> listOfAccountingFiles = mainEm.createNamedQuery("AccountingFiles.findAll").getResultList();


    accountingData.setAll(listOfAccountingFiles);

}

        Player(String firstName, String lastName, boolean international) {
            this.firstName = new SimpleStringProperty(this, "firstName",
                    firstName);
            this.lastName = new SimpleStringProperty(this, "lastName", lastName);
            this.selected = new SimpleBooleanProperty(this, "selected",

        public String getFirstName() {
            return firstName.get();
        }

        public void setFirstName(String firstName) {
            this.firstName.set(firstName);

        public void setLastName(String lastName) {
            this.lastName.set(lastName);
        }

        public StringProperty lastNameProperty() {
            return lastName;
        }

        public boolean isSelected() {
            return selected.get();
        }

        public void setSelected(boolean international) {
            this.selected.set(international);
        }

        public BooleanProperty selectedProperty() {
            return selected;
        }

        @Override
        public String toString() {
            return firstName.get() + " " + lastName.get()
                    + (selected.get() ? " (injured)" : "");
        }
    }
}

在选择任何复选框时，这并不会un-check其他复选框，因为我认为这不是一个好主意。如果你希望它以这种方式工作，只需添加循环。

for (Player pl : players) {
    pl.setSelected(false);
}
