解决方案
您需要实现 showCustomView &您的AndroidManifest文件中还需要 hideCustomView WebChromeClient的方法，您需要 android：hardwareAccelerated =true
我在这里发布我的示例项目。
我做的是在我的main.xml中保存一个Framelayout（customContainer），并在这里添加在showCustomView中接收的视图，并在onHide中删除它。相应地隐藏/显示webview。

Hi I created a webview app for my video site. The design of the site is a hybrid that loads for mobile users. Only videos compatible with mobile devices are loaded onto the hybrid. The players are from Vk, dailymotion, youtube, quicktime. The videos only play on sdk 11 and higher but when I click on the player button to go full screen it only stops the video from playing while never launching into full screen mode. I'm including as much code as I can in hopes someone can help me. I've googled this to death with no progress made. Any help would be greatly appreciated.

解决方案
You need to implement showCustomView & hideCustomView method of WebChromeClient, also You need android:hardwareAccelerated="true" in your AndroidManifest File.
I am posting my sample project here.
What i have done is kept one Framelayout(customContainer) in my main.xml, and adding view received in showCustomView here, and removing it in onHide. Also hiding/showing webview accordingly. Below code works perfectly on device.
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.webview"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8"/>
<uses-permission android:name="android.permission.INTERNET"/>
<application android:label="@string/app_name" android:icon="@drawable/ic_launcher"
android:hardwareAccelerated="true">
<activity android:name="MyActivity"
android:configChanges="orientation|keyboardHidden"
android:hardwareAccelerated="true"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>
</manifest>
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<WebView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/webView"
android:layout_gravity="center"
/>
<FrameLayout
android:id="@+id/customViewContainer"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:visibility="gone"
/>
</LinearLayout>
