推荐答案

在将 HTML 内容加载到 WebView 之前添加这些行.

Add these lines before loading HTML content to your WebView.

wv.setWebChromeClient(new WebChromeClient() {
});

来自文档:

为了在您的应用程序中支持内嵌 HTML5 视频，您需要打开硬件加速，并设置一个 WebChromeClient.对于全屏支持，需要实现 onShowCustomView(View, WebChromeClient.CustomViewCallback) 和 onHideCustomView()，getVideoLoadingProgressView() 是可选的.

In order to support inline HTML5 video in your application, you need to have hardware acceleration turned on, and set a WebChromeClient. For full screen support, implementations of onShowCustomView(View, WebChromeClient.CustomViewCallback) and onHideCustomView() are required, getVideoLoadingProgressView() is optional.
