从url查看Android Webview中的pdf文件

Question

我正试图从以下URL在Android WebView中打开一个pdf文件：

http://bijsluiters.fagg-afmps.be/registrationsearchservlet?key=be-tu441865&leaflettype=leafletnl

public class BijsluiterFragment : Android.Support.V4.App.Fragment
{
    //Title = DomainController.Instance.GetWord("BijsluiterTitle");
    private View view;
    private WebView webview;
    private string url;

    public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        view = inflater.Inflate (Resource.Layout.BijsluiterFragment, container, false);
        webview = view.FindViewById<WebView> (Resource.Id.webView);
        webview.Settings.JavaScriptEnabled=true;
        webview.Settings.SetPluginState (WebSettings.PluginState.On);
        if(!String.IsNullOrEmpty(url))
        {
            webview.LoadUrl ("http://docs.google.com/gview?embedded=true&url="+url);
        }
        return view;
    }

    public void SetUrl(string url)
    {
        this.url = url;
    }
}

我也尝试了'LoadWithBaseURL'方法，但也不起作用...

我用这个解决了同样的问题：

if (url.endsWith(".pdf")) {
    try {
         String urlEncoded = URLEncoder.encode(url, "UTF-8");
         url = "http://docs.google.com/viewer?url=" + urlEncoded;
    } catch (UnsupportedEncodingException e) {
         e.printStackTrace();
    }

}

希望对你有帮助！！
