By extending the ListCell Class, you can customize the listcells.
For example, below snippet defines 'ListColorCell' class that paints the listcell with given color.
private static class ListColorCell extends ListCell {
@Override
public void updateItem(String item, boolean empty) {
if (item == null) {
return;
}
super.updateItem(item, empty);
Rectangle rect = new Rectangle(400, 20);
rect.setFill(Color.web(item));
setGraphic(rect);
}
}
The content of the cell is represented by setGraphic method.
Find the below working application.
ListViewApp.java
package com.sample.demos;
import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.scene.Scene;
import javafx.scene.control.ListCell;
import javafx.scene.control.ListView;
import javafx.scene.layout.VBox;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;
public class ListViewApp extends Application {
public static final ObservableListString> colors = FXCollections.observableArrayList();
private static class ListColorCell extends ListCellString> {
@Override
public void updateItem(String item, boolean empty) {
if (item == null) {
return;
}
super.updateItem(item, empty);
Rectangle rect = new Rectangle(400, 20);
rect.setFill(Color.web(item));
setGraphic(rect);
}
}
@Override
public void start(Stage primaryStage) {
final ListViewString> listView = new ListView(colors);
listView.setCellFactory((ListViewString> l) -> new ListColorCell());
colors.addAll("tomato", "chocolate", "salmon", "gold", "powderblue", "coral", "darkorchid", "fuchsia",
"darkgoldenrod", "lightsalmon", "black", "rosybrown", "blue", "papayawhip", "blueviolet",
"darkturquoise", "brown");
VBox vBox = new VBox(listView);
primaryStage.setScene(new Scene(vBox, 400, 250));
primaryStage.setTitle("List View Sample");
primaryStage.show();
}
}
TestFX.java
package com.sample.demos;
import javafx.application.Application;
public class TestFX {
public static void main(String args[]) {
Application.launch(ListViewApp.class, args);
}
}
