Question

我想执行以下操作：编辑单元格，将数据保存到FXCollections.observableArrayList中，然后填充表格。

FXMLController：

@FXML void initialize（）{ 断言nickColumn！= null：＆＃34; fx：id = \＆＃34; nickColumn \＆＃34;没有注入：检查你的FXML文件＆＃39; Scene.fxml＆＃39;。＆＃34 ;; 断言groupColumn！= null：＆＃34; fx：id = \＆＃34; groupColumn \＆＃34;未注入：检查您的FXML文件＆＃39; Scene.fxml＆＃39;。＆＃34;;

PlayerList playerList = new PlayerList();

playerTable.setItems(playerList.playerList);

nickColumn.setCellValueFactory(new PropertyValueFactory<Player,String>("nick"));
nickColumn.setCellFactory(TextFieldTableCell.forTableColumn());

groupColumn.setCellValueFactory(new PropertyValueFactory<Player,String>("group"));
yearOfBirthColumn.setCellValueFactory(new PropertyValueFactory<Player,Integer>("yearOfBirth"));
ageColumn.setCellValueFactory(new PropertyValueFactory<Player,Integer>("age"));
genderColumn.setCellValueFactory(new PropertyValueFactory<Player,String>("gender"));
lastOnlineColumn.setCellValueFactory(new PropertyValueFactory<Player,String>("lastOnline"));

}

Player.java：

/*
 * To change this license header, choose License Headers in Project Properties.
 * To change this template file, choose Tools | Templates
 * and open the template in the editor.
 */
package de.freakyonline.ucone;

import java.time.format.FormatStyle;
import javafx.beans.property.SimpleIntegerProperty;
import javafx.beans.property.SimpleStringProperty;

/**
 *
 * @author uwe
 */
public class Player {
    private SimpleStringProperty nick;
    private SimpleStringProperty group;
    private SimpleStringProperty gender;
    private SimpleIntegerProperty yearOfBirth;
    private SimpleIntegerProperty age;
    private SimpleStringProperty lastOnline; 


    public Player (String nick, String group, int yearOfBirth, int age, String gender, String lastOnline) {
        this.nick = new SimpleStringProperty(nick);
        this.group = new SimpleStringProperty(group);
        this.gender = new SimpleStringProperty(gender);
        this.age = new SimpleIntegerProperty(age);
        this.lastOnline = new SimpleStringProperty(lastOnline);
        this.yearOfBirth = new SimpleIntegerProperty(yearOfBirth);

        System.out.println("In Player Class:" + lastOnline);
    }

    public String getNick () {
        return nick.get();
    }

    public String getGroup () {
        return group.get();
    }

    public String getGender () {
        return gender.get();
    }

    public int getYearOfBirth() {
        return yearOfBirth.get();
    }

    public int getAge() {
        return age.get();
    }

    public String getLastOnline() {
        return lastOnline.get();
    }

    public void setNick (String nick) {
        this.nick.set(nick);
    }

    public void setGroup (String group) {
        this.group.set(group);
    }

    public void setGender (String gender) {
        this.gender.set(gender);
    }

    public void setYearOfBirth (int yearOfBirth) {
        this.yearOfBirth.set(yearOfBirth);
    }

    public void setAge (int age) {
        this.age.set(age);
    }

    public void setLastOnline (String lastOnline) {
        this.lastOnline.set(lastOnline);
    }

}

PlayerList.java - 这里是列表，之后所有内容都被填充（playerTable.setItems（playerList.playerList）;在FXMLController中：

/*
 * To change this license header, choose License Headers in Project Properties.
 * To change this template file, choose Tools | Templates
 * and open the template in the editor.
 */
package de.freakyonline.ucone;

import de.freakyonline.ucone.Player;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;

/**
 *
 * @author uwe
 */
public class PlayerList {

    ObservableList<Player> playerList;

    public PlayerList() {
        getPlayersFromServer();
    }

    private void getPlayersFromServer() {
        this.playerList = FXCollections.observableArrayList(
        new Player("freakyy85","Owner",1000,1,"m", "missing..."),
        new Player("Ky3ak","Owner",1999,10,"m", "missing...")
        );
    }
}

我已在Scene Builder中将列设置为可编辑。我已添加此内容以使刻痕可编辑：

nickColumn.setCellFactory(TextFieldTableCell.forTableColumn());

我这是为了处理提交单元格的事件（来自内部场景构建器）：

   @FXML
    void handlePlayerEditCommit(ActionEvent event) {
        System.out.println("Commit.");

    }

但按下返回时出现此错误：

所以我需要知道，我必须做些什么才能使PropertyValueFactory和PropertyValueFactory的参数类型不匹配。

非常感谢你的帮助！

JavaFX 8 + Scene Builder +编辑单元＆amp;写回FXCollections.observableArrayList
