Question

我有5个列和3行的tableview。现在我想填写第1行和第2行的数据。请给我看一些示例代码。

这是我的代码 person.java

public class Person {

static int x = 1;
private final SimpleStringProperty firstName = new SimpleStringProperty("");
private final SimpleStringProperty lastName = new SimpleStringProperty("");
private final SimpleStringProperty emailid = new SimpleStringProperty("");
private final Integer iNumber = new Integer(x);

public Person(){
    this("","","");
}

public Person(String fn,String ln,String eid){

    x++;
    setFirstName(fn);
    setLastName(ln);
    setEmailId(eid);  
}

public void setFirstName(String fn){
    firstName.set(fn);
}

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

public void setEmailId(String id){
    emailid.set(id);
}

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

public String getLastName(){
     return lastName.get();
}

public String getEmailId(){
     return emailid.get();
}
}

AddressBookDocumentController.java代码

public class AddressBookDocumentController implements Initializable {

 public AddressBookDocumentController(){
this.personData = FXCollections.observableArrayList(
            new Person("X","Y","Q"),
            new Person("A","B","W"),
            new Person("HAi","Bye","E")

    );
 }

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

    firstName.setCellValueFactory(new PropertyValueFactory<Person,String>("firstName"));
    lastName.setCellValueFactory(new PropertyValueFactory<Person,String>("lastName"));
    emailId.setCellValueFactory(new PropertyValueFactory<Person,String>("emailId"));
     tableId.setItems(personData);

}    

final ObservableList<Person> personData ;
@FXML TableView<Person> tableId;
@FXML TableColumn<Person, String> firstName;
@FXML TableColumn<Person,String> lastName;
@FXML TableColumn<Person,String>emailId;
@FXML TextField tfName;
@FXML TextField tlName;
@FXML TextField tEmail;


@FXML public void handleButtonSave(){

    tableId.getItems().get(0).setFirstName("JOHN"); //HERE CHANGES SHOULD REFLECT BUT IT's NOT HAPPENING 
}
}

谢谢，帕。

Answer 1

将以下JavaFX特定的getter添加到Person类，然后重试：

public SimpleStringProperty firstNameProperty(){
    return firstName;
}

public SimpleStringProperty lastNameProperty(){
    return lastName;
}

public SimpleStringProperty emailidProperty(){
    return emailid;
}

Answer 2

 private final ObservableList<Person> data =
    FXCollections.observableArrayList(
        new Person("", "Smith", ""),

    );



TableColumn col1= new TableColumn("Column1");
    firstNameCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("Column1"));

TableColumn col2= new TableColumn("Column2");
    lastNameCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("Column2"));

TableColumn col3= new TableColumn("Column3");
    lastNameCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("Column3"));

 table.setItems(data);
     table.getColumns().addAll(col1, col2, col3);
