我正在制作一个应用程序,用于在电视机上显示youtube.com/tv。 它有一个简单而漂亮的布局,它还有一些很好的功能,如配对和通过智能手机控制它。 所以.. 我使用webview获取网址:youtube.com/tv
一切正常,exept我希望在选择vid时全屏自动显示。
通常我找到了所有答案,(这里),但这个很难。
我希望所有这些都发生在webview中。那应该是可能的吗?或者我是否需要启动新的意图,或者创建一个新类videoview.java来调用eks。 videoview.xml?真的不确定这个.. 我问的原因是,当vid启动时,youtube.com / tv会像播放列表一样自动播放,很想保持这种状态。
我在http://developer.android.com/reference/android/webkit/WebChromeClient.html#onShowCustomView(android.view.View,android.webkit.WebChromeClient.CustomViewCallback上找到了一些关于HTML5全屏的文档,关于如何做到但仍然困惑。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。请保持温柔,因为我对这些东西很新。
