<任何想法的家伙？
我想要viber中的语音泡泡（android version 5.0.0），但我不知道如何绘制类似的东西...
can任何人都可以帮助我？
谢谢！

c> GeneralPath ...
足够接近？ ）
保护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）;

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（宽度，高度 - 10，宽度，高度，宽度 - 10，高度）;
path.lineTo（15，height）;
path.curveTo（15，height，5，height，5，height - 10）;

I am trying to create beautiful speech bubbles in swing but the result is not very good...I mean I want something better and more beautiful!
here is the code i'm using:
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;

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();
}
}
}
any idea guys?
I want something like speech bubbles in viber (android version 5.0.0) but I don't know how to draw something like that... can anyone help me?
Thanks!
解决方案
finally I draw it with GeneralPath...
close enough? :))
@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);
}
