Android矢量绘制<defs>不支持。如何解决它？

|得到这个错误时，试图从AndroidStudio 2.2生成本地SVG文件矢量资源，Ubuntu的14.04Android矢量绘制<defs>不支持。如何解决它？

Could not generate a preview 
In icon.svg 
[email protected] line 6 <defs> is not supported 
[email protected] line 25 <use> is not supported

Here is the svg icon

我谷歌和发现发生，因为AndroidStudio不支持<defs>，<use> ...
但我不知道如何解决它？
我可以将<defs>更改为AndroidStudio支持的另一个标签吗？
或者我从来不能从这个SVG文件生成矢量素材？
任何帮助或建议将不胜感激。

这完全取决于''和''标签中的内容。但是，如果没有看到文件中的内容，有点难以提出建议。 –

@PaulLeBeau对不起，我的坏解释。我添加了svg图标。我确定当你将这个svg图标导入到AndroidStudio中时，你将会遇到像我一样的错误。我在另一台电脑上测试 –

您的SVG使用<linearGradient>，为了制作模糊的阴影，它使用了SVG滤镜（<filter>）。这些都不受VectorDrawables支持。所以任何解决方案都会涉及到删除这些。

它看起来像是在Sketch中创建的文件。您可以尝试删除Sketch中的这些项目并再次尝试导入。

如果仍然不起作用，那么您可能需要手动修复导入程序不支持的其他元素：<use>。好消息是，解决问题很容易。

我已经在下面包含了一个手动编辑的文件版本，它修复了这三个问题。它应该导入到Android Studio中，但我不知道它是否符合您的审美需求。

直接从草图导入SVG时到Android Studio中我有同样的问题

，我用这个tool将其转换为矢量绘制，然后导入它。

Android矢量绘制<defs>不支持。如何解决它？
