Xamarin Forms Shell: Handling Android Scrolling in WebViews

2019-07-26 13_14_18-android webview xamarin - Google Search.pngXamarin Forms Shell is an awesome new development tool allowing you to build amazing apps faster. Shell takes care of a lot of the plumbing so you can focus more on the app to make your customer happy, rather than the behind the scenes details needed to support your features.

There is a special case you do need to take care of on Android to allow the app to scroll WebViews as there currently is a bug. When a user tries to scroll, it won’t.

Instead of using WebView in your XAML, change that to use a new custom one that simply inherits from WebView:

namespace App.Views.Common
    /// <summary>
    /// Needed for Android scroll issue
    /// </summary>
    public class MyWebView  : WebView

In your XAML reference it will look like this:


Now we add a renderer to the Android project:

[assemblyExportRenderer(typeof(MyWebView), typeof(MyWebViewRenderer))]
namespace App.Droid.Renderers
    class MyWebViewRenderer : WebViewRenderer
        public MyWebViewRenderer(Context context) : base(context)
        protected override void OnElementChanged(ElementChangedEventArgs<WebViewe)
        public override bool DispatchTouchEvent(MotionEvent e)
            return base.DispatchTouchEvent(e);

 iOS requires no changes.
