设置多个按钮- javaFX

Question

我正在用java做一些纸牌游戏。我使用javaFX的用户界面，但我有一个小问题。我有25个按钮，我想添加文本到所有这些。我已经这样做了，但是代码很丑而且很长。我用scenebuilder创建了一个按钮，每个按钮都有唯一的id，从1到25。有没有办法缩短这个代码?

@FXML
Button card1;

card7.setText(board.getListFields().get(6).getWord().name());
card8.setText(board.getListFields().get(7).getWord().name());
card9.setText(board.getListFields().get(8).getWord().name());
card10.setText(board.getListFields().get(9).getWord().name());
card11.setText(board.getListFields().get(10).getWord().name());

card22.setText(board.getListFields().get(21).getWord().name());
card23.setText(board.getListFields().get(22).getWord().name());
card24.setText(board.getListFields().get(23).getWord().name());
card25.setText(board.getListFields().get(24).getWord().name());
}```

Answer 1

大家都说应该在java中而不是在fxml中创建这些项

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

您可以创建一个按钮列表，如下所示:

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

然后遍历它:

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