如何正确使用JavaFX TableView和ObservableList类? [英] How to properly use JavaFX TableView and ObservableList classes?

问题描述

我在一个班上接受了一些集合结构:

I got a class where I receive some collection structure:

public class YIFY {

    private static List<Pelicula> resultados;

    public static void setResultados(List<Pelicula> resultados) {
        YIFY.resultados = resultados;
    }

}

后来，在另一个班级，我将的内容关联到TableView.但是，我创建了一个FXCollections.observableArrayList()，它被设置为表的绑定元素.

Later, at another class I associate the contents of such List to a TableView. However I create an FXCollections.observableArrayList() which is set as the bind element to the table.

这是我的方法:

    peliculas = FXCollections.observableArrayList(YIFY.getResultados());

    tituloColumn.setCellValueFactory(new PropertyValueFactory<>("titulo"));
    calidadColumn.setCellValueFactory(new PropertyValueFactory<>("calidad"));
    imdbColumn.setCellValueFactory(new PropertyValueFactory<>("imdbLink"));
    añoColumn.setCellValueFactory(new PropertyValueFactory<>("año"));
    tableResultados.setItems(peliculas);

tableResultados是TableView，而声明为ObservableList<Pelicula>的鹈鹕自然不会初始化.

Where tableResultados is a TableView and peliculas declared as an ObservableList<Pelicula> naturally not initialized.

我讨厌的是，我认为那不是很好，当我需要在YIFY类上更改/更新resultados时，我还需要这样做:

What I hate and I think is just not that OK is that when I need to change/update resultados at YIFY class, I also need to do:

peliculas.clear();
peliculas.setAll(YIFY.getResultados());

自从YIFY课开始以来，我认为所有这些都应该是 Observable ，但我遇到了很多问题，但未找到沿着Java文档，适当的类实现不是抽象的，因此我不必实现任何其他方法.

I think it all should be an Observable since the beginning at YIFY class, what I tried but I got MUCH problems as I didn't find along the Java docs a proper class implementation which was not abstract so I wouldn't have to implement any extra method.

我该如何管理?我的方法可以吗?

How can I manage this? Is my approach ok?

推荐答案

我不确定我是否真的理解了这个问题，但是那是怎么回事

I'm not sure I really understand the question, but what's wrong with

public class YIFY {
    private static ObservableList<Pelicula> resultados = FXCollections.observableArrayList();

    public static void setResultados(List<Pelicula> resultados) {
        YIFY.resultados.setAll(resultados);
    }
}
