ListView上显示的单元格称为ListCell,自定义ListView子项布局关键在于setCellFactory方法。 /** * 设置要在ListView中使用的新单元格工厂。 * 这迫使所有旧的{@link ListCell}被扔掉,而新的ListCell是用新的单元工厂创建的。 */ public final void setCellFactory(Callback<ListView<T>, ListCell<T>> value) ...
要将自定义的列表项应用于ListView,我们需要在创建ListView时,将自定义列表项类的实例设置为ListView的cellFactory属性。 下面是一个使用自定义列表项的示例代码: importjavafx.application.Application;importjavafx.collections.FXCollections;importjavafx.scene.Scene;importjavafx.scene.control.ListView;importjavafx.scene.lay...
listView.setItems(strList); listView.setPrefSize(400, 200); listView.setCellFactory((ListView<String> l) -> new ColorCell()); listView.setEditable(true); root.getChildren().add(listView); Label label = new Label("..."); label.textProperty().bind(listView.getSelectionModel().selectedItemP...

The visuals of the ListView can be entirely customized by replacing the default cell factory. A cell factory is used to generate ListCell instances, which are used to represent an item in the ListView. See the Cell class documentation for a more complete description of how to write custom Ce...

Step 1:获取ListView的单元格工厂 通过调用`setCellFactory()`方法,获取ListView的单元格工厂。例如: java listView.setCellFactory(param -> newListCell<String>() { @Override protected void updateItem(String item, boolean empty) { super.updateItem(item, empty); if (empty item == null) { setText...
The cell factory is called by the platform whenever it determines that a new cell needs to be created. For example, perhaps your ListView has 10 million items. Creating all 10 million cells would be prohibitively expensive. So instead the ListView skin implementation might only create just enough...
