Ich versuche, schöne Sprechblasen in Schwung zu bringen, aber das Ergebnis ist nicht sehr gut ... Ich meine, ich möchte etwas Besseres und Schöneres!

hier ist der Code, den ich verwende:

import javax.swing.*;
import java.awt.*;
import java.awt.geom.Area;
import java.awt.geom.RoundRectangle2D;

public class BubbleTest {

    public static void main(String[] args) {
        try {
            for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
                if ("Nimbus".equals(info.getName())) {
                    javax.swing.UIManager.setLookAndFeel(info.getClassName());
                    break;
                }
            }
        } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | javax.swing.UnsupportedLookAndFeelException e) {
            e.printStackTrace();
        }
        LeftArrowBubble leftArrowBubble = new LeftArrowBubble();
        JOptionPane.showMessageDialog(null, leftArrowBubble);
        RightArrowBubble rightArrowBubble = new RightArrowBubble();
        JOptionPane.showMessageDialog(null, rightArrowBubble);
    }

    private static class LeftArrowBubble extends JPanel {

        private int strokeThickness = 5;
        private int padding = strokeThickness / 2;
        private int radius = 10;
        private int arrowSize = 6;

        @Override
        protected void paintComponent(final Graphics g) {
            final Graphics2D graphics2D = (Graphics2D) g;
            RenderingHints qualityHints = new RenderingHints(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
            qualityHints.put(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
            graphics2D.setRenderingHints(qualityHints);
            graphics2D.setColor(new Color(80, 150, 180));
            graphics2D.setStroke(new BasicStroke(strokeThickness));
            int x = padding + strokeThickness + arrowSize;
            int width = getWidth() - arrowSize - (strokeThickness * 2);
            int height = getHeight() - strokeThickness;
            graphics2D.fillRect(x, padding, width, height);
            RoundRectangle2D.Double rect = new RoundRectangle2D.Double(x, padding, width, height, radius, radius);
            Polygon arrow = new Polygon();
            arrow.addPoint(14, 6);
            arrow.addPoint(arrowSize + 2, 10);
            arrow.addPoint(14, 12);
            Area area = new Area(rect);
            area.add(new Area(arrow));
            graphics2D.draw(area);
            graphics2D.dispose();
        }

    }

    private static class RightArrowBubble extends JPanel {

        private int strokeThickness = 5;
        private int padding = strokeThickness / 2;
        private int arrowSize = 6;
        private int radius = 10;

        @Override
        protected void paintComponent(final Graphics g) {
            final Graphics2D graphics2D = (Graphics2D) g;
            RenderingHints qualityHints = new RenderingHints(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
            qualityHints.put(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
            graphics2D.setRenderingHints(qualityHints);
            graphics2D.setColor(new Color(20, 130, 230));
            graphics2D.setStroke(new BasicStroke(strokeThickness));
            int width = getWidth() - arrowSize - (strokeThickness * 2);
            int height = getHeight() - strokeThickness;
            graphics2D.fillRect(padding, padding, width, height);
            RoundRectangle2D.Double rect = new RoundRectangle2D.Double(padding, padding, width, height, radius, radius);
            Polygon arrow = new Polygon();
            arrow.addPoint(width, 6);
            arrow.addPoint(width + arrowSize, 10);
            arrow.addPoint(width, 12);
            Area area = new Area(rect);
            area.add(new Area(arrow));
            graphics2D.draw(area);
            graphics2D.dispose();
        }

    }

}

jede Idee Jungs?

Ich möchte so etwas wie Sprechblasen in Viber (Android Version 5.0.0), aber ich weiß nicht, wie ich so etwas zeichnen soll ... kann mir jemand helfen?

Vielen Dank
