java - JFrame 中的重复 JLabel

Question

我正在用JAVA制作UNO游戏。我遇到重复标签的问题。我有一个 JFrame。其中有 7 个 JPanel。每个 JPanel 内部都有一个 JLabel。 JLabels 存储在另一个类的 arrayList 中。每个 JLabel 内部都有一个图像。 arrayList 内部有重复的 JLabel。我将 JLabels 随机放入 JPanels 中。但是当调用重复的 JLabel 时，它会被跳过。请帮忙。

套牌:

public class Deck {
  private ArrayList<JLabel> cards;

Zero zero = new Zero();
One one = new One();
Two two = new Two();
Three three = new Three();
Four four = new Four();
Five five = new Five();
Six six = new Six();
Seven seven = new Seven();
Eight eight = new Eight();
Nine nine = new Nine();
Reverse reverse = new Reverse();
Skip skip = new Skip();
DrawTwo drawTwo = new DrawTwo();
Wild wild = new Wild();
WildDrawFour wildDrawFour = new WildDrawFour();

public Deck() {
    cards = new ArrayList<JLabel>();
    cards.add(zero.getLabelR());
    cards.add(zero.getLabelY());

Answer 1

Swing 组件不能由多个父组件共享。

但是图标可以共享。

因此您的 get() 方法需要更改为获取随机 Icon，而不是随机标签。然后，一旦检索到 Icon，您就创建一个新的 JLabel 并将 Icon 添加到标签中。然后将标签添加到表单中。
