前言
本文主要是將最近工作中遇到的一個問題進行總結分享，主要介紹的是如何讓WebView中H5頁面全屏播放視頻。關于這個問題，做一下簡單分析，希望對大家有所幫助，下面話不多說了，來看看詳細的介紹吧。

運行效果
其實很簡單，就是配置問題。關鍵地方配好了，基本沒什么問題了。
在清單需要配置的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>
這里需要注意的是：啟動硬件加速可以 在application 啟動這個硬件加速，也可以在對應的activity啟動
android:hardwareAccelerated="true"
還有這個
configChanges="orientation|screenSize|keyboardHidden"
必須是
orientation|screenSize|keyboardHidden
當然記得加上網絡權限
<uses-permission android:name="android.permission.INTERNET" />
下面給出全部源碼
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>
