按某些列Javafx对TableView进行排序 [英] Sort TableView by certain column Javafx

问题描述

我正在尝试按特定列对 TableView表进行排序。当我显示表格时，它显示但是从我在这里和其他网站上发现的内容，它让我越来越困惑。

I'm trying to sort a TableView table by a certain column. When I display the table, it's shown but from what I'm finding on here and other sites it's just confusing me more and more.

这里是tableview代码

here is the tableview code

public TableView<Animal> animalLostLocation(ArrayList<Animal> list)
    {

        TableColumn<Animal, String> atypeColumn = new TableColumn<>("Animal Type");
        atypeColumn.setMinWidth(200);
        atypeColumn.setSortable(false);
        atypeColumn.setCellValueFactory(new PropertyValueFactory<>("aType"));

        TableColumn<Animal, String> descriptionColumn = new TableColumn<>("Description");
        descriptionColumn.setMinWidth(200);
        descriptionColumn.setSortable(false);
        descriptionColumn.setCellValueFactory(new PropertyValueFactory<>("description"));

        TableColumn<Animal, String> breedColumn = new TableColumn<>("Breed");
        breedColumn.setMinWidth(80);
        breedColumn.setSortable(false);
        breedColumn.setCellValueFactory(new PropertyValueFactory<>("breed"));

        TableColumn<Animal, String> nameColumn = new TableColumn<>("Name");
        nameColumn.setMinWidth(200);
        nameColumn.setSortable(false);
        nameColumn.setCellValueFactory(new PropertyValueFactory<>("name"));

        TableColumn<Animal, Catergory> catColumn = new TableColumn<>("Category");
        catColumn.setMinWidth(200);
        breedColumn.setSortable(false);
        catColumn.setCellValueFactory(new PropertyValueFactory<>("category"));

        TableColumn<Animal, Integer > ageColumn = new TableColumn<>("Age");
        ageColumn.setMinWidth(50);
        ageColumn.setSortable(false);
        ageColumn.setCellValueFactory(new PropertyValueFactory<>("age"));

        TableColumn<Animal, Integer > idColumn = new TableColumn<>("ID");
        idColumn.setMinWidth(50);
        idColumn.setCellValueFactory(new PropertyValueFactory<>("ID"));

        TableColumn<Animal, Boolean > genColumn = new TableColumn<>("Male");
        genColumn.setMinWidth(50);
        genColumn.setSortable(false);
        genColumn.setCellValueFactory(new PropertyValueFactory<>("gender"));

        table = new TableView<Animal>();

        table.setItems(getAnimal(list));

        table.getColumns().addAll(genColumn, idColumn, nameColumn, atypeColumn, ageColumn, breedColumn, descriptionColumn, catColumn);
        return table;
    }

我想最初按性别对表格进行排序。

I want to sort the table by gender initially.

据我所知，我必须创建一个 SortedList / FilteredList 但是我在网上找到的教程让我更加困惑。

As far as I know I have to create a SortedList/FilteredList but the tutorial I found online is just confusing me even more.

我是否必须使用 SortedList / FilteredList 或有更好的选择吗？

Do I have to use SortedList/FilteredList or are there better alternatives?

这是我找到的一个链接 http://code.makery.ch/blog/javafx-8-tableview-sorting-filtering/

Here's one of the links I found http://code.makery.ch/blog/javafx-8-tableview-sorting-filtering/

任何人都可以愚蠢请问我好吗？

Can anyone dumb it down for me please?

推荐答案

无需自己创建排序列表。只需添加列以按 sortOrder TableView 的列表：

There is no need to create a sorted list yourself. Just add the column to sort by to the sortOrder list of your TableView:

table.getSortOrder().add(genColumn);

根据列中显示的类型，您可能还需要将比较器设置为自己动手（参见 TableColumnBase.comparatorProperty ）

Depending on the types displayed in the column(s), you may also want to set the comparator to use yourself (see TableColumnBase.comparatorProperty)

这种方法的好处是可以使用用户交互提供的排序（点击列标题）而不是排序后备列表（或使用列表的排序视图，这是 SortedList 确实）。

This approach has the benefit of using the sorting provided by user interaction (clicking on the column headers) instead of sorting the backing list (or using a "sorted view" of a list, which is what SortedList does).
