问题是这样的显示5个图片在屏幕上
3 4
2 5
1
当按下右键变成这样:(继续按左键就以此类推逆时针转)
4 5
3 1
2
按下左键变成这样:(继续按左键就以此类推顺时针转)
2 3
1 4
5
我的方法感觉比较笨重:
switch(listIndex){
case 0:
g.drawImage(0, 8, 100, Graphics.TOP | Graphics.LEFT);
g.drawImage(1, 8, 100, Graphics.TOP | Graphics.LEFT);
g.drawImage(2, 16, 80, Graphics.TOP | Graphics.LEFT);
g.drawImage(3, 120, 80, Graphics.TOP | Graphics.LEFT);
g.drawImage(4, 128, 100, Graphics.TOP | Graphics.LEFT);
break;
case 1:
g.drawImage(1, 8, 100, Graphics.TOP | Graphics.LEFT);
g.drawImage(2, 8, 100, Graphics.TOP | Graphics.LEFT);
g.drawImage(3, 16, 80, Graphics.TOP | Graphics.LEFT);
g.drawImage(4, 120, 80, Graphics.TOP | Graphics.LEFT);
g.drawImage(0, 128, 100, Graphics.TOP | Graphics.LEFT);
break;
case 2: g.drawImage(2, 8, 100, Graphics.TOP | Graphics.LEFT);
g.drawImage(3, 8, 100, Graphics.TOP | Graphics.LEFT);
g.drawImage(4, 16, 80, Graphics.TOP | Graphics.LEFT);
g.drawImage(0, 120, 80, Graphics.TOP | Graphics.LEFT);
g.drawImage(1, 128, 100, Graphics.TOP | Graphics.LEFT);
break;
case 3: g.drawImage(3, 8, 100, Graphics.TOP | Graphics.LEFT);
g.drawImage(4, 8, 100, Graphics.TOP | Graphics.LEFT);
g.drawImage(0, 16, 80, Graphics.TOP | Graphics.LEFT);
g.drawImage(1, 120, 80, Graphics.TOP | Graphics.LEFT);
g.drawImage(2, 128, 100, Graphics.TOP | Graphics.LEFT);
break;
case 4: g.drawImage(4, 8, 100, Graphics.TOP | Graphics.LEFT);
g.drawImage(0, 8, 100, Graphics.TOP | Graphics.LEFT);
g.drawImage(1, 16, 80, Graphics.TOP | Graphics.LEFT);
g.drawImage(2, 120, 80, Graphics.TOP | Graphics.LEFT);
g.drawImage(3, 128, 100, Graphics.TOP | Graphics.LEFT);
break;
}
按键改变listIndex的值
有没有简单点的算法呢!
------解决方案--------------------------------------------------------
说一下我个人的看法.
如果图片比较少,这种方法是最简单直观的了.
如果拓展到N多图片,那么最好把图片们都放入一个数组中.好比images[].
设置一个偏移量d = 0;
g.drawImage(image[(0 + d) % n], 8, 100, Graphics.TOP | Graphics.LEFT);
