Android如何让WebView中的HTML5页面实现视频全屏播放

前言

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。

• 硬件加速
• 设置webview
  

在清单需要配置的androidmanifest.xml

<application
 android:allowbackup="true"
 android:icon="@mipmap/ic_launcher"
 android:label="@string/app_name"
 android:supportsrtl="true"
 android:theme="@style/apptheme">
 <activity
 android:name=".webviewactivity"
 android:configchanges="orientation|screensize|keyboardhidden"
 android:hardwareaccelerated="true">
 <intent-filter>
  <action android:name="android.intent.action.main" />
  <category android:name="android.intent.category.launcher" />
 </intent-filter>
 </activity>
</application>

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

<uses-permission android:name="android.permission.internet" />

下面给出全部源码

activity_webview.xml

<?xml version="1.0" encoding="utf-8"?>
<framelayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/mframelayout"
 android:layout_width="match_parent"
 android:layout_height="match_parent">

 <webview
 android:id="@+id/mwebview"
 android:layout_width="match_parent"
 android:layout_height="match_parent" />
</framelayout>
