WebView，无法正确加载 html

Question

我试图通过 AsyncTask 使用 HttpUrlConnection 将网页加载到 WebView 中变得更聪明。以前我使用 WebView 的 .loadurl()

我用 http://www.google.co.uk 测试过，似乎工作正常。我从日志中得到下面的输出，不幸的是我无法确定加载这个特定页面的实际问题是什么。

我想不通的是为什么它谈论的是支持或不支持的音频/视频编解码器。网页与这些无关

将 HTML 加载到 webview 时，我使用：

view.loadData(result, "text/html; charset=UTF-8", null);

抱歉提出如此直率的问题。

Answer 1

这个问题归结为网页 HTML 不足。包括 <!DOCTYPE HTML> 解决了这个问题。 Logcat 错误的相关性仍然未知

导致此问题的另一个问题是对样式和 javascript 资源使用相对路径。我有一个网页视图指向的 iframe。由于我将 HTML 直接加载到视图中，因此视图不知道到哪里寻找资源。我想虽然使用 loadDataWithBaseUrl() 会解决这个问题。然而，这并没有。

作为修复，我不得不将我的 HTML 页面上的所有相对路径更改为静态。
