how to implement tap gesture in webview to display html not website - xamarin.forms

Question

I need my web view to be tappable and scrolable. Once I implement on touch the scroll doesnt work. This way i managed to get it working however now i dont know how to make the web view tappable? the ButtonPress does nothing and if i use Move then i am just scrolling
This my my render in mu droid project
class ExtendedWebViewClient : WebViewClient
{
WebView _webView;
public async override void OnPageFinished(WebView view, string url)
{
try
{
_webView = view;
if (_xwebView != null)
{
view.Settings.JavaScriptEnabled = true;
await Task.Delay(100);
string result = await _xwebView.EvaluateJavaScriptAsync("(function(){return document.body.scrollHeight;})()");
_xwebView.HeightRequest = Convert.ToDouble(result);
}
base.OnPageFinished(view, url);
}
catch (Exception ex)
{
Console.WriteLine($"{ex.Message}");
}
}
public override bool ShouldOverrideUrlLoading(Android.Webkit.WebView view, IWebResourceRequest request)
{
return true;
}
}
protected override void OnElementChanged(ElementChangedEventArgs<Xamarin.Forms.WebView> e)
{
base.OnElementChanged(e);
_xwebView = e.NewElement as ExtendedWebView;
_webView = Control;
if (e.OldElement == null)
{
_webView.SetWebViewClient(new ExtendedWebViewClient());
}
if (e.OldElement != null)
{
Control.Touch -= ControlOnTouch;
Control.ScrollChange -= ControlOnScrollChange;
}
if (e.NewElement != null)
{
Control.Touch += ControlOnTouch;
Control.ScrollChange += ControlOnScrollChange;
}
}
private void ControlOnScrollChange(object sender, ScrollChangeEventArgs scrollChangeEventArgs)
{
if (scrollChangeEventArgs.ScrollY > 0 && scrollChangeEventArgs.OldScrollY == 0)
{
Control.Parent.RequestDisallowInterceptTouchEvent(true);
}
}
private void ControlOnTouch(object sender, Android.Views.View.TouchEventArgs e)
{
// Executing this will prevent the Scrolling to be intercepted by parent views
switch (e.Event.Action)
{
case MotionEventActions.Down:
Control.Parent.RequestDisallowInterceptTouchEvent(true);
break;
case MotionEventActions.Up:
Control.Parent.RequestDisallowInterceptTouchEvent(false);
break;
case MotionEventActions.ButtonPress:
Console.WriteLine("press");
break;
case MotionEventActions.Mask:
Console.WriteLine("mask");
break;
}
// Calling this will allow the scrolling event to be executed in the WebView
Control.OnTouchEvent(e.Event);
}

Instead of using the gesture recognizer on your webview, you can use the Focused event like following . It will been invoked when you tap the WebView .
var wb = new WebView
{
HorizontalOptions = LayoutOptions.FillAndExpand,
VerticalOptions = LayoutOptions.FillAndExpand,
Source = "xxx",
};
wb.Focused += (sender, event) =>
{
//Handle your logic here!
wb.Unfocus();
};
Unfocus() is used if you want to implement your logic everytime the webview is tapped.
