本文主要是将最近工作中遇到的一个问题进行总结分享，主要介绍的是如何让WebView中H5页面全屏播放视频。关于这个问题，做一下简单分析，希望对大家有所帮助，下面话不多说了，来看看详细的介绍吧。
效果图
运行效果
其实很简单，就是配置问题。关键地方配好了，基本没什么问题了。
在清单需要配置的AndroidManifest.xml
这里需要注意的是：启动硬件加速可以 在application 启动这个硬件加速，也可以在对应的activity启动
android:hardwareAccelerated="true"
还有这个
configChanges="orientation|screenSize|keyboardHidden"
必须是
orientation|screenSize|keyboardHidden
当然记得加上网络权限
