我在 JLabel 中进行 HTML 渲染时遇到问题。我不太确定会发生什么,但是当我第一次调用 setFadedVisible 时,它​​似乎计算了未呈现 html 的大小,绘制它,呈现 html,重新计算并重新绘制 agian。在正确重新粉刷之前,我只能瞥见错误的尺寸,但这足以让我恼火。当我将非 HTML 文本放入 textlabel 时,它不会发生(因为我猜它是单行)。你能帮我解决这个问题吗?

public class LevelEndLayeredPane extends FadedLayer {
    ...

    private void showMessageAndSetVisible(String mes) {
        mes = mes.replaceAll("\n", "<br>");
        mes = "<html><center>" + mes + "</center></html>";
        textLabel.setText(mes);
        setFadedVisible(true);
    }
    ...
}


public class FadedLayer extends JLayeredPane{

private JComponent fadedLayer;
private JComponent groundLayer;
private JComponent topLayer;

public FadedLayer(JComponent groundLayer) {
    setLayout(new OverlayLayout(this));
    setOpaque(false);
    createFadedLayer();
    add(groundLayer, Integer.valueOf(0));
    add(fadedLayer, Integer.valueOf(1));
    fadedLayer.setVisible(false);
}

public FadedLayer(JComponent groundLayer, JComponent topLayer) {
    this(groundLayer);
    setTopLayer(topLayer);
}

public void setFadedVisible(boolean show){
    fadedLayer.setVisible(show);
}

public boolean isFadedVisible() {
    return fadedLayer.isVisible();
}
...

}
