Question

我使用webview播放来自varios网站的视频，其中一些还有一个全屏按钮

enter image description here

我希望webview能够响应全屏按钮。

如果我设置webSettings.setUseWideViewPort(false);，那么当点击全屏按钮时视频会卡住，我可以在logcat上看到以下错误：

10-09 08:32:27.970: D/gralloc(31814): unmmap  pid(1876), vaddr(0x589dc000)

我正在使用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);
}
