android - 如何在 Android webview 中播放全屏 youtube 视频？

Question

我是 Android 开发人员的新手。我有 2 个问题:

1. 如何在点击播放标志后立即制作全屏视频？
2. 当视频处于正常大小并且用户想要滚动具有页眉且处于静态模式的页面时，视频将覆盖页眉。当用户滚动到标题时，它应该在标题下方。当用户将页面滚动到标题位置时，如何使视频位于标题下方？

这是我的代码:

        String widthAndHeight = "width='220' height='200'";
        String videoURL = "http://www.youtube.com/v/AyeJyctGhSc&feature=youtube_gdata";

        String temp = "<object "+widthAndHeight+">" +
        "<param name='allowFullScreen' value='false'>" +
        "</param><param name='allowscriptaccess' value='always'>" +
        "</param><embed src='"+ videoURL +"'" +
        " type='application/x-shockwave-flash' allowscriptaccess='always' allowfullscreen='true'" + widthAndHeight +
        "></embed></object>";

        video.getSettings().setPluginState(PluginState.ON);
        video.getSettings().setJavaScriptEnabled(true);
        video.getSettings().setJavaScriptCanOpenWindowsAutomatically(false);
        video.getSettings().setPluginsEnabled(true);
        video.getSettings().setSupportMultipleWindows(false);
        video.getSettings().setSupportZoom(false);
        video.setVerticalScrollBarEnabled(false);
        video.setHorizontalScrollBarEnabled(false);
        video.loadData(temp,"text/html", "utf-8");

使用此源播放 Youtube 视频

        String video = "<iframe class=\"youtube-player\" style=\"border: 0; width: 100%; height: 100%; padding:0px; margin:0px\" id=\"ytplayer\" type=\"text/html\" src=\"http://www.youtube.com/embed/"
                + youtubeId +
                "?autoplay=1"
                + "&fs=0\" frameborder=\"0\">\n"
                + "</iframe>\n";
        mWebview.getSettings().setPluginState(PluginState.ON);
        mWebview.setWebChromeClient(new WebChromeClient());
        mWebview.getSettings().setJavaScriptEnabled(true);
        mWebview.setHorizontalScrollBarEnabled(false);
        mWebview.setVerticalScrollBarEnabled(false);
        mWebview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        mWebview.getSettings().setBuiltInZoomControls(false);
        mWebview.getSettings().setAppCacheEnabled(true);
        mWebview.setInitialScale(0);
        mWebview.getSettings().setLoadWithOverviewMode(true);
        mWebview.getSettings().setUseWideViewPort(true);
        mWebview.loadData(video,"text/html","UTF-8");
