dataWebView.setWebViewClient(new VbLinksWebClient() {
     @Override
     public void onPageFinished(WebView webView, String url) {
           super.onPageFinished(webView, url);
     }
});




public class VbLinksWebClient extends WebViewClient
{
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url)
    {
        view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url.trim())));
        return true;
    }
}

检查您的url是否正确。对我来说，url前面有一个不需要的空格。

通过意图查看简单的网站，

Intent viewIntent = new Intent("android.intent.action.VIEW", Uri.parse("http://www.yoursite.in"));
startActivity(viewIntent);  

使用这个简单的代码在android应用程序中查看您的网站。

在清单文件中添加internet权限，

<uses-permission android:name="android.permission.INTERNET" /> 

试试看：

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);

这对我来说很好。

至于缺少的“http://”，我会这样做：

if (!url.startsWith("http://") && !url.startsWith("https://"))
   url = "http://" + url;

我也可能会预先填充用户键入URL时使用“http://”的EditText。

尝试此代码

AndroidManifest.xml

只需使用简短的一个，即可在浏览器中打开您的Url：

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("YourUrlHere"));
startActivity(browserIntent);
