无法将数据加载到TableView

Question

我无法将数据加载到表中。我有player类，其名称为、lastname等。我想将name、lastname插入到TextField上的表播放器中。

public class CoreAppFXMLController implements Initializable {

@FXML
private Button addBtn;
@FXML
private Button deleteBtn;
@FXML
private Tab playersTab;
@FXML
private Tab coachesTab;
@FXML
private TextField playerNameFld;
@FXML
private TextField playerLNFld;
@FXML
private TextField playerNumberFld;
@FXML
private TextField playerPointsFld;
@FXML
private ChoiceBox<String> positionCb;
@FXML
private TableColumn<Player, String> playerNameCol;
@FXML
private TableColumn<Player, String> playerLNCol;
@FXML
private TableColumn<Player, String> playerNumberCol;
@FXML
private TableColumn<Player, String> playerPointsCol;
@FXML
private TableView<Player> playerTable;

ObservableList<Player> data = FXCollections.observableArrayList();

public class Player {

    private String name;
    private String lastName;
    private String number;
    private String points;

    public Player(String name, String lastName, String number, String points) {
        this.name = name;
        this.lastName = lastName;
        this.number = number;
        this.points = points;

    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getLastName() {
        return lastName;
    }

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

    public String getNumber() {
        return number;
    }

    public void setNumber(String number) {
        this.number = number;
    }

    public String getPoints() {
        return points;
    }

    public void setPoints(String points) {
        this.points = points;
    }

}

/**
 * Initializes the controller class.
 */
public void initialize(URL url, ResourceBundle rb) {

    positionCb.setItems(FXCollections.observableArrayList("PLAYMAKER",
            "SHOOTER", "WING", "CENTER", "CENTER-WING"));

    playerNameCol
            .setCellValueFactory(new PropertyValueFactory<Player, String>(
                    "name"));
    playerLNCol
            .setCellValueFactory(new PropertyValueFactory<Player, String>(
                    "lastName"));
    playerNumberCol
            .setCellValueFactory(new PropertyValueFactory<Player, String>(
                    "number"));
    playerPointsCol
            .setCellValueFactory(new PropertyValueFactory<Player, String>(
                    "points"));

    playerTable.setItems(data);

}

public void addBtnAction(ActionEvent event) {
    data.add(new Player(playerNameFld.getText(), playerLNFld.getText(),
            playerNumberFld.getText(), playerPointsFld.getText()));
    playerNameFld.clear();
    playerLNFld.clear();
    playerNumberFld.clear();
    playerPointsFld.clear();

}

public void deleteBtnAction(ActionEvent event) {

}

我正在执行与下面所示完全相同的操作:http://docs.oracle.com/javase/8/javafx/user-interface-tutorial/table-view.htm#cjagaaee

但我不能让它起作用。有人能帮我吗？

它与示例并不完全相同，如果您使用的是Java7，那么它的工作方式可能并不完全相同。尝试将Player类设置为对成员变量使用SimpleStringProperty，然后为每个变量添加一个*property()方法来返回成员。例如：

public class Player
{
    private SimpleStringProperty name;

    public Player(String name)
    {
        this.name.set(name);
    }

    public SimpleStringProperty nameProperty() { return name; }
    public String getName() { return name.get(); }
    public void setName(String name) { this.name.set(name); }
}

试试看，以同样的方式添加其他成员。
