我没有路径值，我只绘制了所有内容.你是说这有可能吗?

I don't have a path value, I'm only drawing it all. Are you saying this is possible?

请帮助我们很多.预先谢谢你.

推荐答案

第一

• 将您的svg文件拖放到此在线工具中 SVGOMG
• 切换到标记"标签.
• 复制path xml标记的d属性.

• Drag your svg file into this online tool SVGOMG
• Switch to the Markup tab.
• Copy d attribute of the path xml tag.

第二

• 直接使用 react-native-svg 渲染您的svg文件

• Render your svg file directly using react-native-svg

react-native-svg已安装并链接

将显示主页"图标的示例:

Example that would render Home icon:

<Svg
  width="20"
  height="20"
  viewBox="0 0 512 512" // Has to be the same of the original svg file
>
  <Path
    d="M208 448V320h96v128h97.6V256H464L256 64 48 256h62.4v192z"
    fill="red"
  />
</Svg>

这将为您节省加载和读取文件的成本...

This 'd save you as well the cost of loading and reading file ...
