android - android webview 全屏显示 youtube.com/tv 视频

Question

我正在制作一个用于在电视机上显示 youtube.com/tv 的应用程序。它具有简单而漂亮的布局，并且还具有一些不错的功能，例如通过智能手机配对和控制它。所以.. 我使用 webview 来获取网址：youtube.com/tv

一切正常，除了我希望它在选择 vid 时自动全屏显示。

通常我已经找到了我所有的答案，（在这里）但是这个很难。

我希望一切都发生在 webview 中。那应该可以吗？还是我需要开始一个新的意图，或者创建一个新类 videoview.java 来调用 eks。视频视图.xml？对此真的不确定.. 我问的原因是，当一个视频开始时，youtube.com/tv 会像播放列表一样自动播放下一个，希望保持这种状态。

我在http://developer.android.com/reference/android/webkit/WebChromeClient.html#onShowCustomView(android.view.View , android.webkit.WebChromeClient.CustomViewCallback)找到了一些关于 HTML5 全屏的文档，但是仍然很困惑。这是要走的路吗？使用：

public void onShowCustomView(View view, WebChromeClient.CustomViewCallback callback)

和：

public void onHideCustomView ()

这是我的主要 TV.java 直到现在。请温柔一点，因为我对这些东西很陌生。
