一.webView獲取html頁面中標簽的方法：

1.在WebViewClient里的onPageFinished回調方法中執行js代碼：

view.loadUrl("javascript:console.log('MAGIC'+document.getElementById('wxImg')['src']);");

2.在WebChromeClient里的onConsoleMessage回調方法中截取LOG信息：

@Override public boolean onConsoleMessage(ConsoleMessage consoleMessage) {if (consoleMessage.message().startsWith("MAGIC")) {String msg = consoleMessage.message().substring(5); // strip off prefixcom.youku.util.Logger.d("dazhu_IntegratedWebView", "msg : " + msg);if (!TextUtils.isEmpty(msg)) {if (oritationChangeActivity != null)oritationChangeActivity.setReceiveImage(msg);}return true;}return super.onConsoleMessage(consoleMessage); }

二.支持縮放，電腦網頁適配手機屏幕

// 支持縮放 wb.getSettings().setBuiltInZoomControls(true); wb.getSettings().setSupportZoom(true); // 電腦網頁最小化適配手機屏幕 wb.getSettings().setUseWideViewPort(true); wb.getSettings().setLoadWithOverviewMode(true);

三.app與webview共用cookie.前提訪問網絡用的是HttpURLConnection。

private void initCookie() {android.webkit.CookieSyncManager.createInstance(this);// unrelated, just make sure cookies are generally allowedandroid.webkit.CookieManager.getInstance().setAcceptCookie(true);// magic starts hereWebkitCookieManagerProxy coreCookieManager = new WebkitCookieManagerProxy(null, java.net.CookiePolicy.ACCEPT_ALL);java.net.CookieHandler.setDefault(coreCookieManager);}

?

public class WebkitCookieManagerProxy extends CookieManager {private android.webkit.CookieManager webkitCookieManager;public WebkitCookieManagerProxy(){this(null, null);}public WebkitCookieManagerProxy(CookieStore store, CookiePolicy cookiePolicy){super(null, cookiePolicy);this.webkitCookieManager = android.webkit.CookieManager.getInstance();}@Overridepublic void put(URI uri, Map<String, List<String>> responseHeaders) throws IOException{// make sure our args are validif ((uri == null) || (responseHeaders == null)) return;// save our url onceString url = uri.toString();// go over the headersfor (String headerKey : responseHeaders.keySet()){// ignore headers which aren't cookie relatedif ((headerKey == null) || !(headerKey.equalsIgnoreCase("Set-Cookie2") || headerKey.equalsIgnoreCase("Set-Cookie"))) continue;// process each of the headersfor (String headerValue : responseHeaders.get(headerKey)){this.webkitCookieManager.setCookie(url, headerValue);}}}@Overridepublic Map<String, List<String>> get(URI uri, Map<String, List<String>> requestHeaders) throws IOException{// make sure our args are validif ((uri == null) || (requestHeaders == null)) throw new IllegalArgumentException("Argument is null");// save our url onceString url = uri.toString();// prepare our responseMap<String, List<String>> res = new java.util.HashMap<String, List<String>>();// get the cookieString cookie = this.webkitCookieManager.getCookie(url);// return itif (cookie != null) res.put("Cookie", Arrays.asList(cookie));return res;}@Overridepublic CookieStore getCookieStore(){// we don't want anyone to work with this cookie store directlythrow new UnsupportedOperationException();} }
