直接调用Android的webview加载URL时，由于需要登录的session导致URL无法显示，解决方案是在需要访问的URL中加session：
String reporturl = "http://xxx.xxx.xx";
CookieSyncManager.createInstance(getApplication());
CookieManager cookieManager = CookieManager.getInstance();
CookieSyncManager.getInstance().startSync();
List<Cookie> sessionCookie = MyApplication.getAppCookie();
String re= cookieManager.getCookie(reporturl);
if (sessionCookie != null) {
for (int i = 0; i < sessionCookie.size(); i++) {
Cookie cookie = sessionCookie.get(i);
String cookieString=cookie.getName() + "=" + cookie.getValue() //path与Domain必须加上
+ "; path=" + cookie.getPath()
+ "; domain=" + cookie.getDomain();
cookieManager.setCookie(reporturl, cookieString);
}
String re2= cookieManager.getCookie(reporturl);
CookieSyncManager.getInstance().sync();
}
其中sessionCookie是在登录时放入MyApplication中的：
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params, "UTF-8")); httpClient.getParams().setIntParameter("http.socket.timeout", 3000); HttpResponse response = httpClient.execute(httpPost); String result = EntityUtils.toString(response.getEntity(),HTTP.UTF_8); Log.d(TAG, "HTTP Response: " + result); List<Cookie> cookies = httpClient.getCookieStore().getCookies(); MyApplication.setAppCookie(cookies);
然后可以加载URL了：
myWebView.getSettings().setJavaScriptEnabled(true); myWebView.getSettings().setSupportZoom(true); myWebView.getSettings().setAppCacheEnabled(true); //设置缓存模式 myWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT); myWebView.loadUrl(reporturl); myWebView.getSettings().setBuiltInZoomControls(true); myWebView.getSettings().setUseWideViewPort(true); myWebView.getSettings().setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN); myWebView.getSettings().setLoadWithOverviewMode(true); myWebView.setWebViewClient(new WebViewClient(){ public boolean shouldOverrideUrlLoading(WebView view, String url) { //重写此方法表明点击网页里面的链接还是在当前的webview里跳转，不跳到浏览器那边 view.loadUrl(url); return true; }});
