Question

我尝试从对象列表中加载 Tableview 组件，在我的案例中是客户端对象。客户端对象包含地址对象和反之亦然。 客户端和地址对象定义如下;

public class Client{

   private String firstName;
   private String lastName;
   private String emailAddress;
   private String phoneNumber;

   private Address clientsAddress;

   public Client(){
     //blah blah
   }

   //getters
   ...
   //setters
   ...
}

public class Address{

   //address lines + county
   private String a1;
   private String a2;
   private String a3;
   private String county;

   private Client client;

   public Address(){
     //blah blah
   }

   //getters
   ...
   //setters
   ...
}

我可以将客户端字段显示在表视图中，将客户端Object中的字段名称映射到列。

final TableView<Client> tableView = new TableView<>();
final TableColumn firstNameCol = new TableColumn("First Name");
final TableColumn lastNameCol = new TableColumn("Last Name");
final TableColumn emailCol = new TableColumn("Email Address");
final TableColumn addressCol1 = new TableColumn("Address Line 1");
final TableColumn addressCol2 = new TableColumn("Address Line 2");

firstNameCol.setMinWidth(90);
firstNameCol.setMaxWidth(110);
firstNameCol.setCellValueFactory(new PropertyValueFactory<>("firstName"));

lastNameCol.setMinWidth(90);
lastNameCol.setMaxWidth(110);
lastNameCol.setCellValueFactory(new PropertyValueFactory<>("lastName"));

emailCol.setMinWidth(100);
emailCol.setMaxWidth(210);
emailCol.setCellValueFactory(new PropertyValueFactory<>("emailAddress"));

//Don't know how to access the Address Object inside Client Object in Next two parts

addressColumn1.setMinWidth(100);
addressColumn1.setMaxWidth(200);
addressColumn1.setCellValueFactory(new PropertyValueFactory<>(""));

adddessColumn2.setMinWidth(100);
addressColumn2.setMaxWidth(200);
addressColumn2.setCellValueFactory(new PropertyValueFactory<>(""));

tableView.getColumns().addAll(firstNameCol, lastNameCol, emailCol, addressColumn1, addressColumn2);

我的问题是，是否有任何方法可以访问客户端对象中的地址对象，或者将Address对象中的字段名称映射到表列的任何方式。任何帮助将不胜感激，谢谢。

感谢您的提示，我通过覆盖能够访问客户端对象的调用方法来实现它。然后我能够访问地址对象并返回 SimpleStringProperty 并相应地更新每一列。

addressColumn1.setCellValueFactory(new Callback<CellDataFeatures<Client, String>, ObservableValue<String>>() {
        @Override
        public ObservableValue<String> call(CellDataFeatures<Client, String> c) {
            return new SimpleStringProperty(c.getValue().getAddress().getA1());                
        }
});
