Question

我正在构建JFrame，我想在其上有3个JLabel个实例，有3种不同的颜色。

WHITE
RED
WHITE

这是我的代码：

package View;

import java.awt.*;
import javax.swing.*;

public class Home extends JFrame {

    private JLabel label, label1;
    private JPanel panel;
    private Container window = getContentPane();

    public Home (){
        initGUI();
    }

    public void initGUI(){
        setLayout(null);
        setTitle("");
        setPreferredSize(new Dimension(800,600));
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        label = new JLabel();       
        label.setBounds(0, 0, 266, 800);
        label.setBackground(Color.WHITE);
        label.setOpaque(true);
        this.add(label);

        panel = new JPanel();

        pack();
    }
}

但是当我添加第二个标签时，红色必须站在白色背景旁边，白色背景会消失

使用html作为文本标签

public class test {

public static void main(String[] args) {
    String initialText = "<html>\n" +
    "Color and font test:\n" +
    "<table>"+
    "<ul>\n" +
    "<tr>"+
    "<td bgcolor=\"#C0C0C0\">"+
    "<li><font color=red>red</font>\n" +
    "</td>"+
    "</tr>"+
    "<tr>"+
    "<td bgcolor=\"#FF0000\">"+
    "<li><font color=blue>blue</font>\n" +
    "</td>"+
    "</tr>"+
    "<tr>"+
    "<td bgcolor=\"#800000\">"+
    "<li><font color=green>green</font>\n" +
    "</td>"+
    "</tr>"+
    "<tr>"+
    "<td bgcolor=\"#FFFF00\">"+
    "<li><font size=-2>small</font>\n" +
    "</td>"+
    "</tr>"+
    "<tr>"+
    "<td bgcolor=\"#808000\">"+
    "<li><font size=+2>large</font>\n" +
    "</td>"+
    "</tr>"+
    "<tr>"+
    "<td bgcolor=\"#00FFFF\">"+
    "<li><i>italic</i>\n" +
    "</td>"+
    "</tr>"+
    "<tr>"+
    "<td bgcolor=\"#008080\">"+
    "<li><b>bold</b>\n" +
    "</td>"+
    "</tr>"+
    "</ul>\n"+
    "</table>"
    ;
    JFrame f = new JFrame("This is a test");
    f.setSize(400, 150);
    Container content = f.getContentPane();
    content.setBackground(Color.white);
    content.setLayout(new FlowLayout()); 
    content.add(new JLabel(initialText));


    f.setVisible(true);
  }

}

在标签中使用多种背景颜色
