更新時(shí)間：2017年04月23日 10:20:54 作者：愛(ài)開(kāi)發(fā)

最近在工作遇到一個(gè)需求，需要讓W(xué)ebView中的HTML5頁(yè)面實(shí)現(xiàn)視頻全屏播放的效果，通過(guò)查找相關(guān)的資料終于找到了解決的方法，所以想著分享給大家，所以本文介紹了關(guān)于Android如何讓W(xué)ebView中的HTML5頁(yè)面實(shí)現(xiàn)視頻全屏播放的相關(guān)資料，需要的朋友可以參考學(xué)習(xí)。

前言

本文主要是將最近工作中遇到的一個(gè)問(wèn)題進(jìn)行總結(jié)分享，主要介紹的是如何讓W(xué)ebView中H5頁(yè)面全屏播放視頻。關(guān)于這個(gè)問(wèn)題，做一下簡(jiǎn)單分析，希望對(duì)大家有所幫助，下面話不多說(shuō)了，來(lái)看看詳細(xì)的介紹吧。

運(yùn)行效果

其實(shí)很簡(jiǎn)單，就是配置問(wèn)題。關(guān)鍵地方配好了，基本沒(méi)什么問(wèn)題了。

硬件加速
設(shè)置WebView

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(dòng)硬件加速可以在application 啟動(dòng)這個(gè)硬件加速，也可以在對(duì)應(yīng)的activity啟動(dòng)

android:hardwareAccelerated="true"

還有這個(gè)

configChanges="orientation|screenSize|keyboardHidden"

必須是

orientation|screenSize|keyboardHidden

當(dāng)然記得加上網(wǎng)絡(luò)權(quán)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"?>

 android:layout_width="match_parent"
