我目前正在开发我的第一个真正的blackJack程序。它快完成了，但我遇到了一个大问题。
当我运行代码时，它会按计划在中央JPanel中显示玩家卡。但一旦我完成并按下结束转弯，就会只显示经销商卡，而不是同时显示两者。在调整我的卡片图像的大小使其变小之前，它们会显示为又高又窄的条带（只显示卡片中间的一条带，而不是整个东西），从上到下覆盖整个屏幕。
我相信，一旦我结束转弯，卡片图像被添加到南JPanel，它就会最小化中心JPanel（假设是因为组件太高了），并最终占据所有空间。虽然我不确定是不是这样，但这只是猜测。
即使我把图像缩小了，尽管现在整张卡都出现了，但经销商的卡仍然在取代屏幕上的玩家卡。所以我假设我需要以某种方式调整为图像分配的实际空间的大小？
通过stackoverflow搜索，我相信我需要使用gridbglayout并调整卡片的实际空间，但我似乎找不到任何线索来描述如何实际调整大小，尽管我一整天和昨天都在为这个问题而挣扎。
所以，是的，任何帮助或见解都将不胜感激！事先谢谢。
如果你想用卡片，我做了两个zip文件；一张有大卡片，一张有调整大小的卡片：
原始尺寸（大）：http://www.filedropper.com/cardsoriginalsizebigzip
调整大小：http://www.filedropper.com/cardsresizedsmallzip
我的代码：（请记住，它还没有完全完成，我仍然需要修复重新启动游戏按钮，添加一些信息，错误处理等，所以不要担心。此外，这是我的第一个学期，我的老师根本没有帮助我，所以我的编程风格可能真的很糟糕，但请耐心等待，因为我尽了最大努力。）

给你，试试这个，我把它改成了网格图像中的图像
