我使用下面的代码在包含 的 android WebView 中播放视频，我将视频和海报图像放在 Assets 文件夹中。
vWebview = (WebView)findViewById(R.id.VWebview);
vWebview.getSettings().setJavaScriptEnabled(true);
vWebview.getSettings().setPluginsEnabled(true);
ViewContent(raw);
InputStream fileStream = getResources().openRawResource(R.raw.test);
int fileLen = fileStream.available();
byte[] fileBuffer = new byte[fileLen];
fileStream.read(fileBuffer);
fileStream.close();
String displayText = new String(fileBuffer);
vWebview.loadDataWithBaseURL("fake://not/needed", displayText, "text/html", "utf-8", "");
html文件是这样的:
<!DOCTYPE HTML>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Hello World</title>
<body>
<div>
<p>
<video src="file:///android_asset/bigbuck.m4v" poster="file:///android_asset/test.jpg" onclick="this.play();"/>
</p>
</div>
</body>
</html>
它工作正常。海报图片显示正确，我一点击它就出现错误:

最佳答案
我将视频文件放在 RAW 文件夹中，并通过以下代码访问 default.html 文件中的视频文件:
video.src ="android.resource://ProjectPackageAame/raw/bigbuck";
video.type = "video/mp4";
video.load();
video.play();
它按我想要的方式播放视频。还在 AndroidManifest 文件中添加了以下行。
android:hardwareAccelerated="true"
