                document.getElementById("masthead").remove();
                document.getElementsByClass("site-footer clearfix").remove();
                document.getElementsByTag("<p>").remove();

            } catch (IOException e) {
                e.printStackTrace();
            }
            return document;
        }

        @Override
        protected void onPostExecute(final Document document) {
            super.onPostExecute(document);
            webView.loadDataWithBaseURL(url, document.toString(), "text/html", "utf-8", "");
            webView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
            webView.setWebViewClient(new WebViewClient() {
                @Override
                public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
                    return true;
                }

                @Override

                    super.onPageFinished(view, url);


                }
            });

        }
    }

这应该是正确的方法

document = Jsoup.connect(url).get();
            document.getElementById("masthead").remove();
            document.getElementsByClass("site-footer").remove(); 
            document.getElementsByTag("p").remove();
