setText 到许多按钮 - javaFX

Question

我正在用 java 开发一些纸牌游戏。我正在将 javaFX 用于用户界面，但我有一点问题。我有 25 个按钮，我想为所有按钮添加文本。我已经完成了，但是代码很丑而且很长。我正在使用 scenebuilder 并在那里创建了按钮，每个按钮的唯一 id 为 1 到 25。有没有办法缩短此代码？

   @FXML

Answer 1

当他们说你应该在 java 中而不是在 fxml 中创建这些项目时，每个人的意思就是这样

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {

        GridPane gridPane = new GridPane();

        //This is so you can access them later
        ArrayList<Button> buttonList = new ArrayList<>();

        for (int i = 1; i <= 5; i++) {
            for (int j = 1; j <= 5; j++) {
                Button button = new Button();
                button.setText("Card:"+i*j);
                button.setPrefSize(80,120);
                //If you need to know what card it is add the below line
                button.setId(String.valueOf(i*j));

                buttonList.add(button);

                gridPane.add(button, i, j);
            }
        }

        Scene scene = new Scene(gridPane);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

}

Answer 2

您可以创建如下按钮列表：

List<Button> buttons = Arrays.asList(card1, card2, card3, ..., card25);

然后对其进行迭代：

for (int i = 0; i < buttons.size(); i++) {
    buttons.get(i).setText(board.getListFields().get(i).getWorld().name());
}
