Question

我使用此代码在webview中呈现pdf：

        webView.Settings.JavaScriptEnabled = true;
        webView.Settings.AllowFileAccess = true;
        webView.Settings.AllowUniversalAccessFromFileURLs=true;
        webView.Settings.LoadWithOverviewMode = true;
        webView.Settings.UseWideViewPort = true;
        webView.SetWebViewClient(new PDFWebViewClient());
        string pdf = "http://www.adobe.com/devnet/acrobat/pdfs/pdf_open_parameters.pdf";
        webView.LoadUrl ("http://docs.google.com/viewer?embedded=true&url="+pdf);
        webView.Invalidate ();

问题是pdf被切断并且没有填满webView的宽度。滚动也非常滞后

webviewclient（内部类）：

class PDFWebViewClient : WebViewClient 
{

    public override bool ShouldOverrideUrlLoading (WebView view, string url)
    {
        view.LoadUrl(url);
        return true;
    }
}

应用程序输出/控制台在滚动时显示：

[webclipboard] clipservice: android.sec.clipboard.ClipboardExManager@41bf5db8
WIDTHSCALE 1.25
[WML_SISO] InitPasteboardJni
[SlidingMenu] setting padding
[CustomViewBehind] behind INVISIBLE
[OpenGLRenderer] Flushing caches (mode 0)
[GATE] <GATE-M>DEV_ACTION_COMPLETED</GATE-M>
[skia] xxxxxxxxxxxxxxxxxx clip not implemented
[skia] xxxxxxxxxxxxxxxxxx clip not implemented
[skia] xxxxxxxxxxxxxxxxxx clip not implemented

在WebView中加载pdf很慢并且大小不正确
