问题
我编写了一个自定义 Webview，用于播放嵌入在我网站中的 youtube 视频以全屏显示.
I have written an custom Webview for playing youtube video embedded in my website to go full Screen.
但它仍然不起作用...请帮助
But its still not Working...kindly Help

推荐答案
要实现这一点，您应该:
To achieve this you should:
- 实现
WebChromeClient的showCustomView和hideCustomView方法. - 在
AndroidManifest.xml中将android:hardwareAccelerated="true"设置为您的MainActivity.
- Implement
showCustomViewandhideCustomViewmethods ofWebChromeClient. - Set
android:hardwareAccelerated="true"to yourMainActivityinAndroidManifest.xml.
有两个类继承了代码中的 WebChromeClient(myWebChromeClient 和 MyWebChromeClient).第一个实现了 showCustomView 和 hideCustomView 方法，它似乎完全适用于全屏视频.第二个不要.但是您(意外地?)将第二个设置为 WebChromeClient 到您的 WebView.
There are two classes that inherit the WebChromeClient in your code (myWebChromeClient and MyWebChromeClient). The first implements showCustomView and hideCustomView methods and it seems fully working with full-screen video. The second one don't. But you (accidentally?) set the second as WebChromeClient to your WebView.
要解决这个问题，只需更改行
To fix this just change the line
webView.setWebChromeClient(new MyWebChromeClient());
到
mWebChromeClient = new myWebChromeClient();
webView.setWebChromeClient(mWebChromeClient);
在您的 initWebView() 方法中.
UPD:
要在正常(非全屏)模式下锁定纵向的方向，请将以下行添加到 onHideCustomView() 方法中:
To lock orientation on portrait in normal (not full-screen) mode add following line into onHideCustomView() method:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
为了让系统决定全屏模式下的最佳方向，将此行添加到onShowCustomView(View view, CustomViewCallback callback)方法:
To let the system decide the best orientation in full-screen mode add this line to onShowCustomView(View view, CustomViewCallback callback) method:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
