在Swing中画出美丽的泡泡

Question

我想在秋千上创造美丽的泡泡，但结果不是很好...我的意思是我想要更好，更漂亮的东西！

这里是代码我使用：

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(); 
     } 

    } 

} 

任何想法的家伙？

我想要像viber（安卓版本5.0.0）中的语音气泡，但我不知道如何画这样的东西... 任何人都可以帮助我吗？

谢谢！

最后我GeneralPath绘制...

足够接近？ :)）

@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.setPaint(new Color(80, 150, 180)); 
    int width = getWidth(); 
    int height = getHeight(); 
    GeneralPath path = new GeneralPath(); 
    path.moveTo(5, 10); 
    path.curveTo(5, 10, 7, 5, 0, 0); 
    path.curveTo(0, 0, 12, 0, 12, 5); 
    path.curveTo(12, 5, 12, 0, 20, 0); 
    path.lineTo(width - 10, 0); 
    path.curveTo(width - 10, 0, width, 0, width, 10); 
    path.lineTo(width, height - 10); 
    path.curveTo(width, height - 10, width, height, width - 10, height); 
    path.lineTo(15, height); 
    path.curveTo(15, height, 5, height, 5, height - 10); 
    path.lineTo(5, 15); 
    path.closePath(); 
    graphics2D.fill(path); 
}
