我如何将图像绘制到JPanel或JFrame,我已经阅读了oracle的教程,但我似乎无法正确的.我需要将图像“BeachRoad.png”显示在一组特定的坐标上.这是我到目前为止.
public class Level1 extends JFrame implements ActionListener {
static JlayeredPane EverythingButPlayer;
static Level1 l1;
public Level1() {
EverythingButPlayer = new JlayeredPane();
BufferedImage img = null;
try {
img = ImageIO.read(new File("BeachRoad.png"));
} catch (IOException e) {
}
Graphics g = img.getGraphics();
g.drawImage(img,EverythingButPlayer);
this.add(EverythingButPlayer);
}
在Main()中,
l1 = new Level1();
l1.setTitle("poop");
l1.setSize(1920,1080);
l1.setDefaultCloSEOperation(JFrame.EXIT_ON_CLOSE);
l1.setVisible(true);
提前致谢！
解决方法
尝试这个：
package com.sandBox;
import javax.imageio.ImageIO;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.WindowConstants;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
public class SwingSandBox {
public static void main(String[] args) throws IOException {
JFrame frame = buildFrame();
final BufferedImage image = ImageIO.read(new File("C:\\Projects\\MavenSandBox\\src\\main\\resources\\img.jpg"));
JPanel pane = new JPanel() {
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawImage(image,null);
}
};
frame.add(pane);
}
private static JFrame buildFrame() {
JFrame frame = new JFrame();
frame.setDefaultCloSEOperation(WindowConstants.EXIT_ON_CLOSE);
frame.setSize(200,200);
frame.setVisible(true);
return frame;
}
}
