最近做Android的Webview开发，使用iframe中嵌入了很多页面，嵌入的页面却不可用，最后发现是

webView.setWebViewClient(new WebViewClient() { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { return super.shouldOverrideUrlLoading(view, url); } |
不要覆写
shouldOverrideUrlLoading
这个方法，覆写这个方法会拦截ifame中的事件。
补充知识：Android 原生WebView访问使用iFrame网页问题（页面找不到了）
问题：
项目使用原生WebView访问使用了iFrame的网页出现的问题，列表页使用iFrame跳转到淘宝客的地址，单独访问淘宝客地址是能够打开。但列表页跳转过去总是提示“页面找不到了”，尝试很多方法，最终发现是WebView对第三方Cookie支持的问题。
解决：
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
CookieManager.getInstance().setAcceptThirdPartyCookies(mWebView, true);
