Android Webview Custom Renderer

I have my custom renderer working well for iOS but can't seem to figure out how these items translate to Android:

Here is iOS:

    protected override void OnElementChanged(VisualElementChangedEventArgs e)
    {
        base.OnElementChanged (e);
        if (e.OldElement == null) 
        {   
            var webView = this;

            Frame = new System.Drawing.RectangleF(0, 0, UIScreen.MainScreen.Bounds.Width-10, 1);

            webView.ScrollView.ScrollEnabled = false;

            webView.LoadFinished += (sender, f) => 
            {
                webView.SizeToFit();
                float height = webView.ScrollView.ContentSize.Height;
                Frame = new System.Drawing.RectangleF(0, 0, UIScreen.MainScreen.Bounds.Width-10, height);
            };
        }
    }

What Im unsure of is, in Android, how do I access the LoadFinished event? And How do I set the frame?

Thanks!
