Toast equivalent for Xamarin Forms

Question

Is there any way using Xamarin Forms (not Android or iOS specific) to have a pop-up, like Android does with Toast, that needs no user interaction and goes away after a (short) period of time?

From searching around all I'm seeing are alerts that need user clicks to go away.

There is a simple solution for this. By using the DependencyService you can easily get the Toast-Like approach in both Android and iOS.

Create an interface in your common package.

public interface IMessage
{
    void LongAlert(string message);
    void ShortAlert(string message);
}

Android section

[assembly: Xamarin.Forms.Dependency(typeof(MessageAndroid))]
namespace Your.Namespace
{
    public class MessageAndroid : IMessage
    {
        public void LongAlert(string message)
        {
            Toast.MakeText(Application.Context, message, ToastLength.Long).Show();
        }
    
        public void ShortAlert(string message)
        {
            Toast.MakeText(Application.Context, message, ToastLength.Short).Show();
        }
    }
}

iOS section

In iOs there is no native solution like Toast, so we need to implement our own approach.

[assembly: Xamarin.Forms.Dependency(typeof(MessageIOS))]
namespace Your.Namespace
{
    public class MessageIOS : IMessage
    {
        const double LONG_DELAY = 3.5;
        const double SHORT_DELAY = 2.0;

        NSTimer alertDelay;
        UIAlertController alert;

        public void LongAlert(string message)
        {
            ShowAlert(message, LONG_DELAY);
        }
        public void ShortAlert(string message)
        {
            ShowAlert(message, SHORT_DELAY);
        }

        void ShowAlert(string message, double seconds)
        {
            alertDelay = NSTimer.CreateScheduledTimer(seconds, (obj) =>
            {
                dismissMessage();
            });
            alert = UIAlertController.Create(null, message, UIAlertControllerStyle.Alert);
            UIApplication.SharedApplication.KeyWindow.RootViewController.PresentViewController(alert, true, null);
        }

        void dismissMessage()
        {
            if (alert != null)
            {
                alert.DismissViewController(true, null);
            }
            if (alertDelay != null)
            {
                alertDelay.Dispose();
            }
        }
    }
}

Please note that in each platform, we have to register our classes with DependencyService.

Now you can access out Toast service in anywhere in our project.

DependencyService.Get<IMessage>().ShortAlert(string message); 
DependencyService.Get<IMessage>().LongAlert(string message);

Did you try the code? If you toast the second message before first one dismiss, the UI will stuck. The second message will never disappear. – Meng Tim Feb 22 '18 at 16:36
@MengTim I have tried this code and working well, but didn't check with simultaneous toasts. Will check and update here. – Alex Chengalan Feb 26 '18 at 06:00

@MengTim I seem to have fixed the stuck UI by creating a new alert and timer every time. Both need to be passed to `DismissMessage`. – Ian Warburton Jun 11 '18 at 14:58
@Ian Warburton Do you have a code sample for this? Thanks so much. I still need this function. – Meng Tim Jun 14 '18 at 22:01
@AlexChengalan-Could you tell me why interface needed here. However without interface also we can do it. – R15 Aug 22 '18 at 12:42
@Arvindraja Its because I followed something like this: https://xamarinhelp.com/xamarin-forms-dependency-injection/ and I think which is better for dependency injection. – Alex Chengalan Aug 24 '18 at 04:27

Here's a version of Alex Chengalan's iOS code that avoids the UI sticking when multiple messages are shown...

public class MessageIOS : IMessage
    {
        const double LONG_DELAY = 3.5;
        const double SHORT_DELAY = 0.75;

        public void LongAlert(string message)
        {
            ShowAlert(message, LONG_DELAY);
        }

        public void ShortAlert(string message)
        {
            ShowAlert(message, SHORT_DELAY);
        }

        void ShowAlert(string message, double seconds)
        {
            var alert = UIAlertController.Create(null, message, UIAlertControllerStyle.Alert);

            var alertDelay = NSTimer.CreateScheduledTimer(seconds, obj =>
            {

                alertDelay.Dispose();
            }
        }

You can use SnackBar from Xamarin Community toolkit package, which uses native implementation in platforms where natively supported, because Toast is deprecated in API level 30, a SnackBar without an Action is equivalent to a Toast.

This method was deprecated in API level 30. Custom toast views are deprecated. Apps can create a standard text toast with the makeText(android.content.Context, java.lang.CharSequence, int) method, or use a Snackbar when in the foreground. Starting from Android Build.VERSION_CODES#R, apps targeting API level Build.VERSION_CODES#R or higher that are in the background will not have custom toast views displayed. (source).

Starting with Xamarin Community toolkit

Install the Package on all your projects
include the namespace using Xamarin.CommunityToolkit.Extensions;
In your page code-behind show a SnackBar upon an event

await this.DisplayToastAsync("This is a Toast Message");
await this.DisplayToastAsync("This is a Toast Message for 5 seconds", 5000);

You may specify a duration for the SnackBar to disappear (in milliseconds) or leave the default one which equals 3 seconds.

Resources

SnackBar Sample

Official Repo https://github.com/xamarin/XamarinCommunityToolkit

Official Docs https://learn.microsoft.com/en-us/xamarin/community-toolkit/

EDIT

Anchored Toast: You may anchor the toast above a view (like screenshot above) by simply calling the extension method DisplayToastAsync() from that view (anchor) object instead from the page instance (this):

<Button x:name="floatingButton" .../>

await floatingButton.DisplayToastAsync("This is a Toast Message for 5 seconds", 5000);

Padding and corner radius: (starting from xct version 1.3.0 preview-1)

You can set the corner radius and the padding for your Toast like the following example:

var messageOptions = new MessageOptions
{
    Message = "Toast with Padding and round corner",
    Foreground = Color.White,
    Font = Font.SystemFontOfSize(16),
    Padding = new Thickness(20)
};

var options = new ToastOptions
    {
        MessageOptions = messageOptions,
        CornerRadius = new Thickness(40, 40, 0, 0),
        BackgroundColor = Color.FromHex("#CC0000")
    };

await this.DisplayToastAsync(options);

PS: The same properties could be applied for the SnackBar view.

EDIT2

If what xct SnackBar offers doesn't fulfil your requirements or you want to display not only text but some complexe view, you might have to use a popup instead.

I wish I had seen this before trying the top voted answer. Good lord. — Krausladen, Feb 21 '22 at 21:22

Gábor · Answer 5 · 2020-01-14T20:35:19.737

Adding to Alex's answer, here's the UWP variant:

public class Message : IMessage {
  private const double LONG_DELAY = 3.5;
  private const double SHORT_DELAY = 2.0;

  public void LongAlert(string message) =>
    ShowMessage(message, LONG_DELAY);

  public void ShortAlert(string message) =>
    ShowMessage(message, SHORT_DELAY);

  private void ShowMessage(string message, double duration) {
    var label = new TextBlock {
      Text = message,
      Foreground = new SolidColorBrush(Windows.UI.Colors.White),
      HorizontalAlignment = HorizontalAlignment.Center,
      VerticalAlignment = VerticalAlignment.Center,
    };
    var style = new Style { TargetType = typeof(FlyoutPresenter) };
    style.Setters.Add(new Setter(Control.BackgroundProperty, new SolidColorBrush(Windows.UI.Colors.Black)));
    style.Setters.Add(new Setter(FrameworkElement.MaxHeightProperty, 1));
    var flyout = new Flyout {
      Content = label,
      Placement = FlyoutPlacementMode.Full,
      FlyoutPresenterStyle = style,
    };

    flyout.ShowAt(Window.Current.Content as FrameworkElement);

    var timer = new DispatcherTimer { Interval = TimeSpan.FromSeconds(duration) };
    timer.Tick += (sender, e) => {
      timer.Stop();
      flyout.Hide();
    };
    timer.Start();
  }
}

Coloring and styling is up to you, the MaxHeightis actually required to keep the height at the minimum.

So registering it as a Dependency Service does not need for the UWP? — Olorunfemi Davis, Oct 05 '18 at 19:45
It works exactly as the other two variants. Yes, a dependency service. — Gábor, Oct 06 '18 at 07:40

We'd normally use Egors Toasts plugin, but as it requires permissions on iOS for a current project we've gone a different route using Rg.Plugins.Popup nuget (https://github.com/rotorgames/Rg.Plugins.Popup).

I wrote a basic xaml/cs page of type PopupPage,

<?xml version="1.0" encoding="utf-8" ?>
<popup:PopupPage xmlns="http://xamarin.com/schemas/2014/forms"
         xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
         xmlns:popup="clr-namespace:Rg.Plugins.Popup.Pages;assembly=Rg.Plugins.Popup"
         x:Class="YourApp.Controls.ToastPage">
...

and had it created by a service, whose interface you registered at app start or use Xamarin.Forms.DependencyService to fetch the service would be viable too.

The service news up the PopupPage derived page, and does

await PopupNavigation.PushAsync(newToastPage);
await Task.Delay(2000);
await PopupNavigation.PopAllAsync();

The Popup page can be dismissed by the user by tapping outside the page display (assuming it hasn't filled the screen).

This seems to work fine on iOS/Droid, but I'm open to correction if anyone knows what this is a risky way of doing it.

rg popups are great. I do similar workaround for loading display or activity indicator on full page. problem with other plugins are they are dependent on async functions and main thread but rg popup can run on 2nd thread which makes it very useful. good idea indeed but I wish to have native look like on android toasts. — Emil, Jul 16 '18 at 00:28
So far this is the best method to do cross platform toast. Rg.Popup is super flexibile, and i use it in almost every project. No need to use other plugins or platform code to display toasts, — GiampaoloGabba, May 04 '19 at 09:15

You can use IUserDialog NuGet and simply use it's toastAlert

var toastConfig = new ToastConfig("Toasting...");
toastConfig.SetDuration(3000);
toastConfig.SetBackgroundColor(System.Drawing.Color.FromArgb(12, 131, 193));

UserDialogs.Instance.Toast(toastConfig);

@MengTim, to fix the multiple toast issue in @alex-chengalan's solution, I simply wrapped everything within ShowAlert() with a check to see if alert and alertDelay are null, then within DismissMessage, nulled out alert and alertDelay.

void ShowAlert(string message, double seconds)
    {
        if(alert == null && alertDelay == null) {
            alertDelay = NSTimer.CreateScheduledTimer(seconds, (obj) =>
            {
                DismissMessage();
            });
            alert = UIAlertController.Create(null, message, UIAlertControllerStyle.Alert);
            UIApplication.SharedApplication.KeyWindow.RootViewController.PresentViewController(alert, true, null);
        }
    }

    void DismissMessage()
    {
        if (alert != null)
        {
            alert.DismissViewController(true, null);
            alert = null;
        }
        if (alertDelay != null)
        {
            alertDelay.Dispose();
            alertDelay = null;
        }
    }

That seemed to at least clear up the UI hang, if you are looking for a quick fix. I was trying to display the toast on navigation to a new page, and believe that the PresentViewController being set was essentially cancelling out my navigation. Sorry I did not comment within the thread, my reputation is too low :(

This is my improved ShowAlert version of Ian Warburton's version to ensure that the toast is displayed even on popup page. Furthermore, the toast is dissmissed if the user click outside the toast. I used UIAlertControllerStyle.ActionSheet that look likes toast but it also work with UIAlertControllerStyle.Alert

    void ShowAlert(string message, double seconds)
    {
        var alert = UIAlertController.Create(null, message, UIAlertControllerStyle.ActionSheet);

        var alertDelay = NSTimer.CreateScheduledTimer(seconds, obj =>
        {
            DismissMessage(alert, obj);
        });

        var viewController = UIApplication.SharedApplication.KeyWindow.RootViewController;
        while (viewController.PresentedViewController != null)
        {
            viewController = viewController.PresentedViewController;
        }
        viewController.PresentViewController(alert, true, () =>
        {
            UITapGestureRecognizer tapGesture = new UITapGestureRecognizer(_ => DismissMessage(alert, null));
            alert.View.Superview?.Subviews[0].AddGestureRecognizer(tapGesture);
        });
    }

I hope this will help someone !

There is no built-in mechanism in Forms, but this nuget package supplies something similar

https://github.com/EgorBo/Toasts.Forms.Plugin

Note: These are not Android style toasts as requested in the question but UWP style toasts which are system wide notifications.

I customised a custom popup with Rg.Plugins.Popup NuGet this is an example:

        DurationIn="600"
        DurationOut="600"
        EasingIn="Linear"
       EasingOut="Linear"/>
</pages:PopupPage.Animation>

<Frame CornerRadius="10"  
    HeightRequest="30"
       VerticalOptions="End"
       HorizontalOptions="Fill"
       HasShadow="False"
        Padding="0" Margin="40,50"
       OutlineColor="LightGray">
    <StackLayout 
    Opacity="0.4"
       BackgroundColor="White">
    <Label
        x:Name="lbl"
        LineBreakMode="WordWrap"
        HorizontalTextAlignment="Center"

                <Label.FontFamily>
                    <OnPlatform x:TypeArguments="x:String">
                        <On Platform="iOS" Value="NewJuneMedium" />
                    </OnPlatform>
                </Label.FontFamily>
            </Label>
</StackLayout>
    </Frame>

then in your basecontentpage you can add the following code, to show and hide the "toast" after a while:

public async void showpopup(string msg)
    {
        await Navigation.PushPopupAsync(new Toast(msg));
        await Task.Delay(3000);
        await Navigation.PopPopupAsync(true);   
    }

The iOS answers above worked for me but for one little problem -- a warning: Attempt to present UIAlertController ... whose view is not in the window hierarchy!

After some search, I came across this unrelated answer which helped. The poster commented "This looks stupid but works", which is right on both counts.

So, I modified the ShowAlert() function above with these lines, which seem to work:

    var rootVC = UIApplication.SharedApplication.KeyWindow.RootViewController;
    while ( rootVC.PresentedViewController != null) {
        rootVC = rootVC.PresentedViewController;

    rootVC.PresentViewController( alert, true, null);

Install nuget Acr.UserDialogs. It contains Toasts exactly what you are looking for.

ToastEvent toastEvent = new ToastEvent();
var toastConfig = new ToastConfig(toastEvent,"Toasting...","");
toastConfig.SetDuration(2000);

UserDialogs.Instance.Toast(toastConfig);

Currently use xamarin essential in android:

//access mainthread
MainThread.BeginInvokeOnMainThread(() =>
{
     Toast.MakeText(Application.Context, message, ToastLength.Short).Show();       
});

Adding Alex's code, for UWP variant, I found a great implementation here https://www.c-sharpcorner.com/article/xamarin/

Just come and leave a clap for him :)

[assembly:Xamarin.Forms.Dependency(typeof(Toast_UWP))]  
namespace ToastMessage.UWP  
{  
    class Toast_UWP : Toast  
    {  
        public void Show(string message)  
        {  
            ToastTemplateType toastTemplate = ToastTemplateType.ToastImageAndText01;  
            XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(toastTemplate);  
  
            XmlNodeList toastTextElements = toastXml.GetElementsByTagName("text");  
            toastTextElements[0].AppendChild(toastXml.CreateTextNode(message));  
              
            XmlNodeList toastImageAttributes = toastXml.GetElementsByTagName("image");  
            ((XmlElement)toastImageAttributes[0]).SetAttribute("src", "ms-appx:///Assets/Logo.scale-240.png");  
            ((XmlElement)toastImageAttributes[0]).SetAttribute("alt", "logo");  
  
            IXmlNode toastNode = toastXml.SelectSingleNode("/toast");  
            ((XmlElement)toastNode).SetAttribute("duration", "short");  
  
            var toastNavigationUriString = "#/MainPage.xaml?param1=12345";  
            var toastElement = ((XmlElement)toastXml.SelectSingleNode("/toast"));  
            toastElement.SetAttribute("launch", toastNavigationUriString);  
  
            ToastNotification toast = new ToastNotification(toastXml);  
  
            ToastNotificationManager.CreateToastNotifier().Show(toast);  
        }  
    }  
}

By default, your messages will be queued and notified one after one, delayed based on the message duration. If you want to replace the existing message by the new one immediately just add more code like below

ToastNotificationManager.History.Remove("YOUR_TAG");

// Code to create Toast message, like the above method

toast.Tag = "YOUR_TAG";

If you want to add audio to your toast message, add this to your code

var audio = toastXml.CreateElement("audio");
audio.SetAttribute("src", "ms-winsoundevent:Notification.Default");

You could use the Xamarin.Toolkit and follow this information provided by MS. https://learn.microsoft.com/en-us/xamarin/community-toolkit/views/popup

In my application I could manage it by putting every code-thing between a viewmodel, the view and a method called DismissThisPopup(). So it is possible to controll it from outside of the current Mainpage.

To acomplish your request. You could call await Task.Delay(5000); //as example 5sec after you called your popup.Open(); so it might look like:

    ...
var vm = new MyPopUpViewModel()
vm.DisplayText = "this could be your text";
vm.DelayTimeForDismiss = 5000;
vm.IsLightDismissAllowed = false; //used that you can not close the popup by clicking around
await vm.OpenPopupAsync();

then in your vm OpenPopUpAsync()

...other properties and stuff
internal PopUpLoadingView popup = new PopUpLoadingView();//this is the view created with the informations from MS

public async Task OpenPopUp()
{
 popup.BindingContext = this;            
 Application.Current.MainPage.Navigation.ShowPopup(popup: popup);
 await Task.Delay(DelayTimeForDismiss);
 popup.DismissThisPopup();
}

and in your PopUpLoadingView, insert this method:

...other stuff
        public void DismissThisPopup()
        {
            Dismiss(this);
        }

You can use DisplayAlert("", "", "", "" );

This doesn't at all react like a toast, it needs an action to continue. – CennoxX Nov 14 '19 at 11:06
