添加到 actionPerformed 功能：在每个动作之前检查你当前的位置，所以当你按下 f/e 时它是否在左下方。按钮 2 什么都不会发生。或者我没有得到你的问题。

我不想为某些网格禁用某些按钮，但不是为所有网格禁用相同的按钮

GridLayout使用组件的left-to-right方向，它会按照您添加的顺序布置组件。所以对于一个2x2 网格：

 jPanel1.setLayout(new GridLayout(2, 2));

 jPanel1.add(button1); //button1 is at grid (1, 1)
 jPanel1.add(button2); //button2 is at grid (1, 2)
 jPanel1.add(button3); //button3 is at grid (2, 1)
 jPanel1.add(button4); //button4 is at grid (2, 2)

所以，要在网格单元中找到一个组件(row, col)并使用它，实际上很容易：首先，找到组件的索引，然后要求jPanel1返回它：

GridLayout layout = (GridLayout) jPanel1.getLayout();
int numCol = layout.getColumns();
int index = (row-1)*numCol + col-1; 

if(index < jPanel1.getComponentCount())
    jPanel1.getComponent(index).setEnabled(false);

你记下棋子在哪里

 int x=0, y=0;

移动棋子时，检查 x 是否 == 1，如果是，则禁用右侧按钮，如果 == 0，则禁用左侧按钮。然后你对 y 做同样的事情。

每次移动时确保并更新它们。

 //change x and y based on button clicked

 if (x==1)
 {
  //disable right buttons & enable left
 }
 else if (x==0)
 {
 //disable left buttons & enable right
 }

 if (y==1)
 {
  //disable down buttons & enable up
 }
 else if (y==0)
 {
 //disable up buttons & enable down
 }

好吧，我知道我做这个有点晚了，我可能应该比现在早一点回来，但我想分享我开始工作的代码，以防万一还有其他人想要制作棋盘好吧，我只做了一个 2x2，但你可能会从这个扩展
