我使用 webview 播放来自各种网站的视频，其中一些有全屏按钮
我希望 webview 响应全屏按钮。
如果我设置webSettings.setUseWideViewPort(false);然后单击全屏按钮时视频卡住，我可以在 logcat 上看到以下错误：

我使用的是 Android 4.0.1，这是我的代码：
setWebViewSettings(mVideoWebView);
String data_html = "<!DOCTYPE HTML> <html xmlns=\"http://www.w3.org/1999/xhtml\" xmlns:og=\"http://opengraphprotocol.org/schema/\" xmlns:fb=\"http://www.facebook.com/2008/fbml\"> <head></head> <body style=\"margin:0 0 0 0; padding:0 0 0 0;\"> <iframe src=\"http://www.dailymotion.com/embed/video/xu4vre\" width=\"300\" height=\"162"\" frameborder=\"0\"></iframe> </body> </html> ";
mVideoWebView.loadData(data_html, "text/html", null);
public static void setWebViewSettings(WebView webview) {
WebSettings webSettings = webview.getSettings();
webSettings.setPluginState(PluginState.ON);
webSettings.setJavaScriptEnabled(true);
webSettings.setAllowFileAccess(true);
webSettings.setLoadWithOverviewMode(false); // zoom y/n
webSettings.setUseWideViewPort(true); // true = like desktop
webSettings.setPluginsEnabled(true);
//webSettings.setAllowContentAccess(true);
webSettings.setAllowFileAccess(true);
//webSettings.setAllowFileAccessFromFileURLs(true);
//webSettings.setAllowUniversalAccessFromFileURLs(true);
webSettings.setDatabaseEnabled(true);
webSettings.setGeolocationEnabled(true);
webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
webSettings.setDomStorageEnabled(true);
}
