超链接

本文演示了如何在形状上使用 Aspose.Slides for Android via Java 添加、访问、删除和更新超链接。

添加超链接

创建一个矩形形状，并为其添加指向外部网站的超链接。

static void addHyperlink() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
        shape.getTextFrame().setText("Aspose");

        IParagraph paragraph = shape.getTextFrame().getParagraphs().get_Item(0);
        IPortion textPortion = paragraph.getPortions().get_Item(0);
        textPortion.getPortionFormat().setHyperlinkClick(new Hyperlink("https://www.aspose.com"));
    } finally {
        presentation.dispose();
    }
}

访问超链接

读取形状文本部分的超链接信息。

static void accessHyperlink() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
        shape.getTextFrame().setText("Aspose");

        IParagraph paragraph = shape.getTextFrame().getParagraphs().get_Item(0);
        IPortion textPortion = paragraph.getPortions().get_Item(0);
        textPortion.getPortionFormat().setHyperlinkClick(new Hyperlink("https://www.aspose.com"));

        IHyperlink hyperlink = textPortion.getPortionFormat().getHyperlinkClick();
    } finally {
        presentation.dispose();
    }
}

删除超链接

清除形状文本中的超链接。

static void removeHyperlink() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
        shape.getTextFrame().setText("Aspose");

        IParagraph paragraph = shape.getTextFrame().getParagraphs().get_Item(0);
        IPortion textPortion = paragraph.getPortions().get_Item(0);
        textPortion.getPortionFormat().setHyperlinkClick(new Hyperlink("https://www.aspose.com"));

        textPortion.getPortionFormat().setHyperlinkClick(null);
    } finally {
        presentation.dispose();
    }
}

更新超链接

更改现有超链接的目标。使用 HyperlinkManager 修改已包含超链接的文本，这模拟了 PowerPoint 安全更新超链接的方式。

static void updateHyperlink() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
        shape.getTextFrame().setText("Aspose");

        IParagraph paragraph = shape.getTextFrame().getParagraphs().get_Item(0);
        IPortion textPortion = paragraph.getPortions().get_Item(0);
        textPortion.getPortionFormat().setHyperlinkClick(new Hyperlink("https://old.example.com"));

        // 在已存在的文本中更改超链接应通过
        // HyperlinkManager 而不是直接设置属性。
        // 这模拟了 PowerPoint 安全更新超链接的方式。
        textPortion.getPortionFormat().getHyperlinkManager().setExternalHyperlinkClick("https://new.example.com");
    } finally {
        presentation.dispose();
    }
}
