Google文档查看器：删除放大和弹出窗口

Question

我们如何从Android应用中的谷歌文档查看器中删除弹出和放大选项？

我试过这个：但它不会删除弹出图标下方的黑色背景。

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);

        }
    })
