web view始终是一块白板，真的尽力了

怎么老是出不来啊，我都照着视频编写三遍了，保证代码没有错，但是httpurlconnection那节的webview控件就是一块白板

报错如下

上面代码最后一行的警告是你的xml文件或者setcontentview有问题你可以检查一下如果没有问题重启一下

需要注意的几点：如果你是按照视频里的代码全部一样的话视频里用的网站是http://www.baidu.com 现在的百度是https://www.baidu.com 所以要修改网址因为是https方式访问不是http方式所以 HttpsURLconnection conn=(HttpsURLconnection)httpurl.openconnection 最好把你代码发一下看不到代码

感谢！成功了！把重写代码发一下webView.setWebViewClient(new WebViewClient(){ public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) { return super.shouldOverrideUrlLoading(view, request); }});
