我有一个带10x10按钮的GridPane。全部放在名为＆＃39;按钮的ArrayList中。现在我需要知道，当单击一个按钮时，它应该记住一个按钮，当单击另一个按钮时执行一个动作。所以你会得到一个方法 makeTurn（按钮1，按钮2）; 现在问我的问题，我该怎么做？这是我制作GUI的第一堂课

您只需存储在某处点击的第一个Button即可。此外，我建议使用ToggleButton，因为用户可以更清楚地看到哪个Button被按下了：
public class Main extends Application {
private final ObjectProperty<ToggleButton> rememberMe = new SimpleObjectProperty<>();
private final List<ToggleButton> buttons = new ArrayList<>();
@Override
public void start(Stage primaryStage) {
GridPane grid = new GridPane();
grid.setHgap(5);
grid.setVgap(5);
grid.setPadding(new Insets(5));
for (int row = 0; row < 10; row++) {
for (int col = 0; col < 10; col++) {
ToggleButton button = new ToggleButton(row + " | " + col);
button.selectedProperty().addListener((w, o, n) -> {
if (n) {
if(rememberMe.get() != null) {
turn(rememberMe.get() , button);
}
else {
rememberMe.set(button);
}
}
});
grid.add(button, col, row);
buttons.add(button);
}
}
Scene scene = new Scene(grid, 500, 500);
primaryStage.setScene(scene);
primaryStage.show();
}
private void turn(ToggleButton pButton1, ToggleButton pButton2) {
rememberMe.set(null);
System.out.println(pButton1 + " - " + pButton2);
buttons.forEach(tb -> tb.setSelected(false));
}
public static void main(String[] args) {
launch(args);
}
}
从现在开始，创建突出显示和其余游戏逻辑应该非常简单。

您可以使用节点的方法setUserData和getUserData来存储各种信息，例如您是否点击了按钮。
作为替代方案，您可以使用BitSet来存储布尔状态。
