I use following html page to display your svg:我使用以下 html 页面来显示您的 svg：
<html>
<head>
<title>SVG Test</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width">
</head>
<body>
<svg xmlns="http://www.w3.org/2000/svg" height="100%"
preserveAspectRatio="xMidYMid meet" version="1.1"
viewBox="0 0 3288 2188" width="100%"
xmlns:xlink="http://www.w3.org/1999/xlink">
<image width="3288" height="2188"
xlink:href="file:///android_asset/image.jpg"></image>
</svg>
</body>
</html>
To display embedded image into svg you should use path with file:///android_asset/ prefix.要将嵌入的图像显示到 svg 中，您应该使用带有file:///android_asset/前缀的路径。 If you want to embed image from another location then assets folder, you also should use file:/// prefix.如果您想从其他位置嵌入图像，然后是资产文件夹，您还应该使用file:///前缀。

Do you mean you can't change response from server?你的意思是你不能改变服务器的响应？
This case you can wrap <svg> tag with necessary <html> and <body>在这种情况下，您可以使用必要的<html>和<body>包裹<svg>标签
Try this:尝试这个：
String svgContent = ... // Your code of svg here
String pageContent = "<html><head><meta charset='UTF-8'><meta name='viewport' content='width=device-width'></head><body>" + svgContent + "</body></html>";
webview.loadData(pageContent, "text/html", "utf-8");
