Ok, found the answer and here it is!

In order to handle a popup confirmation coming from a webpage in your WebView, you need to override the onJsConfirm method in WebChromeClient to display the popup as an Android Alert dialog. Here is the code to do so.

<pre><code>final Context myApp = this; 
final class MyWebChromeClient extends WebChromeClient {
 @Override
 public boolean onJsConfirm(WebView view, String url, String message, final JsResult result) {
 new AlertDialog.Builder(myApp)
 .setTitle("App Titler")
 .setMessage(message)
 .setPositiveButton(android.R.string.ok,
 new DialogInterface.OnClickListener()
 {
 public void onClick(DialogInterface dialog, int which)
 {
 result.confirm();
 }
 })
 .setNegativeButton(android.R.string.cancel,
 new DialogInterface.OnClickListener()
 {
 public void onClick(DialogInterface dialog, int which)
 {
 result.cancel();
 }
 })
 .create()
 .show();

 return true;
 }
}
</code></pre>

Don't forget to set your WebChromeClient in your WebView...

<pre><code> mWebView.setWebChromeClient(new MyWebChromeClient());
</code></pre>

Note.. this isn't my code, but I found it and it works perfectly for handling javascript confirmation dialogs in a WebView!

Cheers!

Thanks Brockoli for the method. 
I needed this for Xamarin.Android

<pre><code> public class MyWebChromeClient : WebChromeClient
{
 private Context mContext;
 private JsResult res;

 public MyWebChromeClient(Context context)
 {
 mContext = context;
 }


 public override bool OnJsConfirm(WebView view, string url, string message, JsResult result)
 {

 res = result;

 AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
 builder.SetTitle("Confirm:");
 builder.SetMessage(message);
 builder.SetPositiveButton(Android.Resource.String.Ok, OkAction);
 builder.SetNegativeButton(Android.Resource.String.Cancel, CancelAction);
 builder.Create();
 builder.Show();

 return true;


 //return base.OnJsConfirm(view, url, message, result);
 }

 private void CancelAction(object sender, DialogClickEventArgs e)
 {
 res.Cancel();
 }

 private void OkAction(object sender, DialogClickEventArgs e)
 {
 res.Confirm();
 }
}
</code></pre>

This back in the activity where webview is created (web_view)

<pre><code>web_view.SetWebChromeClient(new MyWebChromeClient(this));
</code></pre>

I'm displaying a webpage in a WebView and on the webpage, there is a button. When you click the button, a confirmation dialog is supposed to popup, but it doesn't show in my WebView. It does popup if I go to the same webpage in the android browser. Anyone know how to handle popup dialogs coming from a webpage inside your WebView?

How to handle a webview confirm dialog?

我在WebView中显示网页，网页上有一个按钮。当你点击这个按钮时，一个确认对话框应该会弹出来，但它并没有显示在我的WebView中。如果我在android浏览器中转到相同的网页，它确实会弹出。有谁知道如何在WebView中处理来自网页的弹出对话框？
