How to handle a webview confirm dialog?

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.

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;    }}

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

    mWebView.setWebChromeClient(new MyWebChromeClient());

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

 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();    }}

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

web_view.SetWebChromeClient(new MyWebChromeClient(this));
