我正在从网络服务器下载一个 HTML 表单并在 android webview 上显示该表单。 HTML 文件中的图片很少(图片 src 是用 Base64 编码的)。但是图像没有显示。
问题出在哪里？
myBrowser.loadDataWithBaseURL("", downloadedFormContent , "text/html", "UTF-8", null);
我已将表单内容保存到本地 html 文件 (/sdcard/test.html) 并加载 html 文件。但仍然没有显示图像。
myBrowser.loadUrl("file:///sdcard/test.html");
如果我使用网络浏览器(IE、Chrome)打开同一个 HTML 文件，我可以看到所有图像。
我哪里错了？
Here is the src of html file :
<html>
<head>
<title>Assignment Form</title>
<style type="text/css">
//css goes here

</head>
<body>

最佳答案
只是替换
data:image;base64,
与
data:image/png;base64,
您在 src 中缺少图像的 content-type
关于android - 当我通过 android webview 加载 html 文件时，html 文件中缺少图像，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11947354/
