推荐答案

而不是直接通过视频网址（以下你的例子），我会用在HTML文件中的标记。例如：

Instead of passing directly the video URL (following you example), i would have used tokens in the Html file. For example:

<embed src="$VIDEO_URL$" autostart="false" />

其中 $ VIDEO_URL $ 将令牌至极将与真正的视频在运行时被替换网​​址

where the $VIDEO_URL$ will be the token wich will be replaced during the runtime with a real video URL.

此外，因为你不能在运行时更改您的资产文件夹的内容，你应该在html文件的内容加载到一个字符串变量，并使用替换方法来替代令牌一个真正的网​​址，并最终传递字符串的网页视图。事情是这样的：

Also, since you cannot change the contents of your asset folder during runtime you should load the html file contents into a String variable and use the replace method to replace the token with a real URL and, finally, pass that string to your webview. Something like this:

//The html variable has the html contents of the file stored in the assets folder
//and real_video_url string variable has the correct video url
html = html.replace("$VIDEO_URL$", real_video_url);
webview.loadData(html, "text/html", "utf-8");
