大家好，我有这个 xml 文件:
<?xml version='1.0' encoding='UTF-8'?>
<courses>
<course>

<name>Bohdana Dumanska</name>

</students>
<time>Monday 6:00 - 8:00</time>
<availability>yes</availability>

<maxStudents>30</maxStudents>
</course>
<course>

</course>
</courses>
这样，NetBeans 从 xsd 文件创建了这些类:

还有一个 ObjectFactory，但我认为不需要将其包含在此处。 所以我尝试使用以下方法将 xml 中的所有值插入到表中:
JAXBContext jaxbContext = JAXBContext.newInstance(ObjectFactory.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
courses = (Courses)unmarshaller.unmarshal(new File("courses.xml"));
courseList = FXCollections.observableArrayList(courses.getCourse());
现在我如何将数据设置为单元值工厂。我正在尝试像这样使用 lambdaExpression:
TableColumn name = new TableColumn("Name");
name.setCellValueFactory(cellData -> cellData.toString(courseList....???
我不知道如何将值插入到 tableColumn 中。对于类文件中的所有注释，我深表歉意。 请帮忙。谢谢!
最佳答案
假设您有 TableView<Courses.Course>和一个 TableColumn<Courses.Course, String>我认为你需要
TableColumn<Courses.Course, Name> name = new TableColumn<>("Name");
name.setCellValueFactory(cellData -> new ReadOnlyStringWrapper(cellData.getValue().getName()));
关于java - 如何设置 TableColumnValue JavaFX TableView ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26474481/
