加载了一个图片,怎样让他响应键盘上的方向键移动呢?代码越精简越好!有会的都教下,谢谢!

你先贴一下你的吧..觉得用网格布局..然后监听键盘..对它位置调整...

在窗体事件中写，img为图片对象。至于超过了窗体的大小停止移动，自己比较一下就可以了。
this.addKeyListener(new KeyAdapter(){
            public void keyPressed(KeyEvent arg0) {
                int imgX = (int) img.getLocation().getX();
                int imgY = (int) img.getLocation().getY();
                switch (arg0.getKeyCode()) {
                    case KeyEvent.VK_UP:
                        img.setLocation((int) (imgX),(int) (imgY-5));
                        break;
                    case KeyEvent.VK_DOWN:
                        img.setLocation((int) (imgX),(int) (imgY+5));
                        break;
                    case KeyEvent.VK_LEFT:
                        img.setLocation((int) (imgX-5),(int) (imgY));
                        break;
                    case KeyEvent.VK_RIGHT:
                        img.setLocation((int) (imgX+5),(int) (imgY));
                        break;
                    default:
                        break;
                }    
            }
        });

我写了断代码,可是完全不响应,就把他删掉了,现在在重写,谁能不能帮我写断完整的啊,让我参考下!

你可以把上面代码改一下啊....加个窗体类....自己改才有收获...

    }
    public void paint(Graphics g)
    {
      g.drawImage(img,50,80,this);     
    }
 }
只能写成这样了,好多方法还不会使用,那些方法,使用也有错,高手帮忙改下~,谢谢

上面我错了点，img是jlabel，不是图像对象。。。
给你一个完整的。。

高手啊，代码太长了。不懂~！！！
用java仅仅做图片移动总觉得有点得不偿失的感觉。。

你可以把它改成贪吃蛇..俄罗斯啊..呵呵..思路而已

很有几天又没学JAVA了，伤心，我怎么来的时候看到你老在线上哦，我好像看某某女生的QQ空间里面看到你的头像了，不知道是不是你，呵呵，高手加个QQ357567696啊，
这几天就为做一个简单的迷宫游戏。
