就我个人而言，我会从JList 和HORIZONTAL_WRAP 开始
详情请见How to Use Lists
例如...
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Component;
import java.awt.EventQueue;
import java.awt.Image;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.imageio.ImageIO;
import javax.swing.DefaultListCellRenderer;
import javax.swing.DefaultListModel;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.ListSelectionModel;
public class Main {
public static void main(String[] args) {
new Main();
}
public Main() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
List<Game> games = new ArrayList<>(Arrays.asList(new Game[]{
new Game("Assiassins Creed - Black Flag", ImageIO.read(getClass().getResource("/boxart/AssassinsCreedBlackFlag.png"))),
new Game("Assiassins Creed - Unit", ImageIO.read(getClass().getResource("/boxart/AssassinsCreedUnity.png"))),
new Game("Battlefield 3", ImageIO.read(getClass().getResource("/boxart/BattleField3.png"))),
new Game("BioShock", ImageIO.read(getClass().getResource("/boxart/BioShock.png"))),
new Game("Borderlands", ImageIO.read(getClass().getResource("/boxart/BorderLands.png"))),
new Game("Dead standing", ImageIO.read(getClass().getResource("/boxart/DeadStanding.png"))),
new Game("Dishonored", ImageIO.read(getClass().getResource("/boxart/Dishnonored.png"))),
new Game("Fallout 4", ImageIO.read(getClass().getResource("/boxart/Fallout4.png"))),
new Game("Far Cry Primal", ImageIO.read(getClass().getResource("/boxart/FarCryPrimal.png"))),
new Game("Halflife", ImageIO.read(getClass().getResource("/boxart/HalfLife.png"))),
new Game("Jedi Fallen Order", ImageIO.read(getClass().getResource("/boxart/JediFallenOrde.png"))),
new Game("Kings Quest VII", ImageIO.read(getClass().getResource("/boxart/KingsQueteVII.png"))),
new Game("Leisure Suit Larry in the Land of the Lounge Lizards", ImageIO.read(getClass().getResource("/boxart/LSL.png"))),
new Game("Mass Effect 2", ImageIO.read(getClass().getResource("/boxart/Mass Effect 2.png"))),
new Game("Mass Effect 3", ImageIO.read(getClass().getResource("/boxart/Mass Effect 3.png"))),
new Game("Mass Effect", ImageIO.read(getClass().getResource("/boxart/Mass Effect.png"))),
new Game("Space Quest IV", ImageIO.read(getClass().getResource("/boxart/SpaceQuestIV.png"))),
new Game("Tomb Raider", ImageIO.read(getClass().getResource("/boxart/TombRaider.png"))),
new Game("Zelda - Breath of the wild", ImageIO.read(getClass().getResource("/boxart/Zelda.png")))
}));
JFrame frame = new JFrame();
frame.add(new LaunchPane(games));
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
} catch (IOException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
}
});
}
public class LaunchPane extends JPanel {
public LaunchPane(List<Game> games) {
System.out.println(games.size());
setLayout(new BorderLayout());
DefaultListModel<Game> model = new DefaultListModel<>();
model.addAll(games);
JList list = new JList(model);
list.setBackground(Color.BLACK);
list.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);
list.setLayoutOrientation(JList.HORIZONTAL_WRAP);
list.setCellRenderer(new GameListCellRenderer());
list.setVisibleRowCount(3);
add(new JScrollPane(list));
}
}
public class GameListCellRenderer extends DefaultListCellRenderer {
public GameListCellRenderer() {
setHorizontalAlignment(CENTER);
setVerticalAlignment(CENTER);
setHorizontalTextPosition(CENTER);
setVerticalTextPosition(BOTTOM);
}
@Override
public Component getListCellRendererComponent(JList<?> list, Object value, int index, boolean isSelected, boolean cellHasFocus) {
super.getListCellRendererComponent(list, value, index, isSelected, cellHasFocus);
if (value instanceof Game) {
Game game = (Game) value;
setIcon(new ImageIcon(game.getBoxArt()));
setText(null);
}
return this;
}
}
public class Game {
private String title;
private Image boxArt;
public Game(String title, Image boxArt) {
this.title = title;
this.boxArt = boxArt;
}
public String getTitle() {
return title;
}
public Image getBoxArt() {
return boxArt;
}
}
}
现在，如果您想对其进行更多自定义，您可以创建一个完全自定义的ListCellRenderer，例如...
public class GameListCellRenderer extends JPanel implements ListCellRenderer<Game> {
private static Border EMPTY_BORDER = new EmptyBorder(1, 1, 1, 1);
private static Border SELECTED_BORDER = new LineBorder(Color.BLUE, 1);
private Map<Game, String> cachedTitle = new HashMap<>();
private Map<Game, ImageIcon> cachedIcon = new HashMap<>();
private JLabel titleLabel;
private JLabel artboxLabel;
public GameListCellRenderer() {
setOpaque(false);
titleLabel = new JLabel();
titleLabel.setForeground(Color.WHITE);
artboxLabel = new JLabel();
setLayout(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridwidth = gbc.REMAINDER;
gbc.weightx = 1;
gbc.fill = gbc.HORIZONTAL;
add(artboxLabel, gbc);
add(titleLabel, gbc);
}
@Override
public Component getListCellRendererComponent(JList<? extends Game> list, Game value, int index, boolean isSelected, boolean cellHasFocus) {
ImageIcon icon = cachedIcon.get(value);
if (icon == null) {
icon = new ImageIcon(value.getBoxArt());
cachedIcon.put(value, icon);
}
String title = cachedTitle.get(value);
if (title == null) {
FontMetrics fm = getFontMetrics(titleLabel.getFont());
title = value.getTitle();
if (fm.stringWidth(title) > 150) {
do {
title = title.substring(0, title.length() - 1);
} while (fm.stringWidth(title) > 150);
title = title.substring(0, title.length() - 3) + "...";
}
cachedTitle.put(value, title);
}
titleLabel.setText(title);
artboxLabel.setIcon(icon);
setBorder(isSelected ? SELECTED_BORDER : EMPTY_BORDER);
return this;
}
}
并且在不改变任何其他内容的情况下，它将产生...
