android - 如何删除谷歌文档查看器中的弹出图标？

Question

我在 android 中使用谷歌文档查看器来显示 pdf。我想删除弹出选项。请参阅随附的屏幕截图。 Screenshot of google docs

这是我用来在 webview 中加载的代码。

webview= (WebView) findViewById(R.id.text_studyguide);
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("https://docs.google.com/viewer?embedded=true&url="+pdfURL);
webview.setWebViewClient(new Callback());

private class Callback extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(
            WebView view, String url) {
        view.loadUrl(url);
        return false;
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        // TODO Auto-generated method stub
        super.onPageFinished(view, url);

    }
}

webview.setWebViewClient(new WebViewClient() {
            @Override
            public void onReceivedError(WebView view, int errorCode,
                                        String description, String failingUrl) {

            }

            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return true;
            }

            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                webview.loadUrl("javascript:(function() { " +
                        "document.getElementsByClassName('ndfHFb-c4YZDc-GSQQnc-LgbsSe ndfHFb-c4YZDc-to915-LgbsSe VIpgJd-TzA9Ye-eEGnhe ndfHFb-c4YZDc-LgbsSe')[0].style.display='none'; })()");
            }

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);

            }
        })
