Xamarin.Forms MarkdownTextView NuGet Announcement!

A while back I talked about building your own Markdown Label / TextView to your Xamarin applications including Xamarin Native and Xamarin Forms. I decided to put the control I’ve been working off of over on NuGet so anyone can use its basic form.

Note that this control isn’t final, I am working on some refactoring and enhancements, but if you want something that just works, then give it a shot, or contribute to the repository!

Down below you can find the documentation as it’s found on the GitHub repo!

MarkdownTextView

alt tag

A Xamarin.Forms component to display markdown text in a TextView

Installation

Now on NuGet!

Install-Package MarkdownTextView.Forms

https://www.nuget.org/packages/MarkdownTextView.Forms

Usage

  • Call Init before calling Xamarin.Forms.Init()
  • iOS: SPControls.MarkdownTextView.iOS.MarkdownTextView.Init();
  • Android: SPControls.MarkdownTextView.Droid.MarkdownTextView.Init();
  • Use the control
  • In Xaml:
<ContentPage ...
             xmlns:spcontrols="clr-namespace:SPControls.Forms;assembly=SPControls.MarkdownTextView"
             ...>
  <spcontrols:MarkdownTextView Markdown="{Binding MarkdownString}" />
</ContentPage>
  • or in C#:
var mdTextView = new MarkdownTextView();
mdTextView.Markdown = "# this is my *header* tag";

TODO

  • Add other properties for updating markdown settings
  • Add text color settings
  • Add UWP Support

Xamarin.NuGet – Xamarin.Forms Dynamic Bindable StackLayout

I recently released a component I commonly use in my Xamarin.Forms applications for binding data to a wrapping layout here: Xamarin.NuGet – DynamicWrapLayout Announcement! In the spirit of this type of control, I’ve also released a new NuGet package for a bindable DynamicStackLayout. It’s a simple control that allows you to create a StackLayout and bind an ItemsSource collection and an ItemTemplate. This is useful for smaller, but dynamic collections with the use of the orientation changing of a StackLayout. This means you could have a horizontally scrolling list of cards, bind the orientation or change it to vertical, and play with positioning more easily than using a ListView. I would still highly suggest using a ListView over this control for a standard vertical stack of dynamic content since this control does NOT use any view recycling or virtualization which can cause performance issues with large collections or constantly changing collection.

Get it here

NuGet: https://www.nuget.org/packages/DynamicStackLayout

Github: https://github.com/SuavePirate/DynamicStackLayout

In the end, you get something like this!

Be sure to read the documentation below:

DynamicStackLayout

A Xamarin.Forms layout for creating dynamically wrapped views. Inspired by the WrapLayout example: https://developer.xamarin.com/samples/xamarin-forms/UserInterface/CustomLayout/WrapLayout/

Installation

It’s on NuGet! https://www.nuget.org/packages/DynamicStackLayout/

Install-Package DynamicStackLayout

Be sure to install in all projects that use it.

Usage

There are two key properties that make this control useful – the ItemsSource (like a ListView) and the ItemTemplate (although, you can also just add children to the view – it does both!)
Be sure to wrap it in a ScrollView though

XAML

Add the xmlns:

xmlns:suave=&quot;clr-namespace:SuaveControls.DynamicStackLayout;assembly=SuaveControls.DynamicStackLayout&quot;

Use it in your View:

&lt;ScrollView&gt;
    &lt;suave:DynamicStackLayout ItemsSource=&quot;{Binding Items}&quot; HorizontalOptions=&quot;Fill&quot;&gt;
        &lt;suave:DynamicStackLayout.ItemTemplate&gt;
            &lt;DataTemplate&gt;
                &lt;StackLayout BackgroundColor=&quot;Gray&quot; WidthRequest=&quot;120&quot; HeightRequest=&quot;180&quot;&gt;
                    &lt;Label Text=&quot;{Binding .}&quot; VerticalOptions=&quot;FillAndExpand&quot; HorizontalOptions=&quot;FillAndExpand&quot; VerticalTextAlignment=&quot;Center&quot; HorizontalTextAlignment=&quot;Center&quot; /&gt;
                &lt;/StackLayout&gt;
            &lt;/DataTemplate&gt;
        &lt;/suave:DynamicStackLayout.ItemTemplate&gt;
    &lt;/suave:DynamicStackLayout&gt;
&lt;/ScrollView&gt;

Don’t like data-binding and want to just use child views? You can do that too!

&lt;ScrollView&gt;
    &lt;suave:DynamicStackLayout HorizontalOptions=&quot;Fill&quot;&gt;
      &lt;StackLayout BackgroundColor=&quot;Gray&quot; WidthRequest=&quot;120&quot; HeightRequest=&quot;180&quot;&gt;
          &lt;Label Text=&quot;0&quot; TextColor=&quot;White&quot; VerticalOptions=&quot;FillAndExpand&quot; HorizontalOptions=&quot;FillAndExpand&quot; VerticalTextAlignment=&quot;Center&quot; HorizontalTextAlignment=&quot;Center&quot; /&gt;
      &lt;/StackLayout&gt;
      &lt;StackLayout BackgroundColor=&quot;Gray&quot; WidthRequest=&quot;120&quot; HeightRequest=&quot;180&quot;&gt;
          &lt;Label Text=&quot;1&quot; TextColor=&quot;White&quot; VerticalOptions=&quot;FillAndExpand&quot; HorizontalOptions=&quot;FillAndExpand&quot; VerticalTextAlignment=&quot;Center&quot; HorizontalTextAlignment=&quot;Center&quot; /&gt;
      &lt;/StackLayout&gt;
      &lt;StackLayout BackgroundColor=&quot;Gray&quot; WidthRequest=&quot;120&quot; HeightRequest=&quot;180&quot;&gt;
          &lt;Label Text=&quot;2&quot; TextColor=&quot;White&quot; VerticalOptions=&quot;FillAndExpand&quot; HorizontalOptions=&quot;FillAndExpand&quot; VerticalTextAlignment=&quot;Center&quot; HorizontalTextAlignment=&quot;Center&quot; /&gt;
      &lt;/StackLayout&gt;
      &lt;StackLayout BackgroundColor=&quot;Gray&quot; WidthRequest=&quot;120&quot; HeightRequest=&quot;180&quot;&gt;
          &lt;Label Text=&quot;3&quot; TextColor=&quot;White&quot; VerticalOptions=&quot;FillAndExpand&quot; HorizontalOptions=&quot;FillAndExpand&quot; VerticalTextAlignment=&quot;Center&quot; HorizontalTextAlignment=&quot;Center&quot; /&gt;
      &lt;/StackLayout&gt;
      &lt;StackLayout BackgroundColor=&quot;Gray&quot; WidthRequest=&quot;120&quot; HeightRequest=&quot;180&quot;&gt;
          &lt;Label Text=&quot;4&quot; TextColor=&quot;White&quot; VerticalOptions=&quot;FillAndExpand&quot; HorizontalOptions=&quot;FillAndExpand&quot; VerticalTextAlignment=&quot;Center&quot; HorizontalTextAlignment=&quot;Center&quot; /&gt;
      &lt;/StackLayout&gt;
    &lt;/suave:DynamicStackLayout&gt;
&lt;/ScrollView&gt;

Features

  • Bindable child views
  • Bindable to collections
  • Handles layout changing well (try rotating the device)
  • Doesn’t require custom renderers (All Xamarin.Forms baby!)

Notes

This does not use any native view virtualization, which means performance does not scale well with extremely large data sets.

Coming soon

  • ItemSelected event and SelectedItem bindable property (for now, you can add custom gestures and commands to your DataTemplate and handle the events yourself)
  • Better Collection Updating

Xamarin.iOS RKNotificationHub NuGet Announcement!

More awesome iOS controls coming our way as Xamarin developers! I’ve gone ahead and added another UI control to NuGet which is an incredibly useful little notification manager to add badges to any control or any frame in our view.

Check out the NuGet and GitHub project:

NuGet: https://www.nuget.org/packages/RKNotificationHub/
GitHub: https://github.com/SuavePirate/Xamarin-RKNotificationHub

Documentation


Xamarin RKNotificationHub

A Xamarin.iOS library for adding badges to any UIView, UIBarButtonItem, or position on the screen. You can also animate your badges!

Installation

Use NuGet!
Install-Package RKNotificationHub
https://www.nuget.org/packages/RKNotificationHub/

Usage

Once installed, create an RKNotificationHub.

var hub = new RKNotificationHub.RKNotificationHub(myView);
// or...
var hub = new RKNotificationHub.RKNotificationHub(myUIBarButtonItem);
// or...
var hub = new RKNotificationHub.RKNotificationHub();

You can then set or change the view or position of the circle:

hub.SetView(myView);
hub.SetCircleAtFrame(myFrame);

You can also set the color:

hub.SetCircleColor(circleColor, labelColor);

Then you can change the value of the notifcation:

hub.Increment();
hub.IncrementBy(10);
hub.Decrement();
hub.DecrementBy(10);
hub.HideCount();
hub.ShowCount();

And of course you can play with styles and animations!

hub.Bump();
hub.Blink();
hub.Pop();
hub.MoveCircleByX(x,y);
hub.ScaleCircleSizeBy(3);

Xamarin iOS Expanding Splash View NuGet Announcement!

Here’s another fun NuGet package I’ve put up for everyone: The ExpandingSplashView is a Xamarin.iOS Binding implementation of the CBZSplashView from CallumBoddy on GitHub: https://github.com/callumboddy/CBZSplashView

It allows you to create a quick expanding view and add it to any ViewController very easily. It also allows for you to create the expanding view from either a rasterized image such as a png icon, or from a vector icon using a UIBezierPath.

Here’s the NuGet Package: https://www.nuget.org/packages/ExpandingSplashView

And the GitHub project for the binding and NuGet: https://github.com/SuavePirate/ExpandingSplashView

Be sure to read the documentation either below here or on the GitHub project!

Documentation


CBZSplashView

A Xamarin.iOS implementation of the popular iOS control CBZSplashView from @callumboddy

Credit where credit is due (I just spent a couple hours fighting with the binding libraries, but @callumboddy did the real work): https://github.com/callumboddy/CBZSplashView

Installation

You can either clone the repository and reference the CBZSplashView project, or you can now use NuGet!

Install-Package ExpandingSplashView

https://www.nuget.org/packages/ExpandingSplashView

Usage

This can be used on any view, but is best suited for covering an entire UIViewController. Simply create either a CBZSplashViewCBZRasterSplashView, or CBZVectorSplashView via their constructors or the static initializer within the CBZSplashView:

var splashView = new CBZRasterSplashView(someUIImage, someUIColor);

Then add the splashview to your View:

View.Add(splashView);

Then start your animation whenever you want:

splashView.StartAnimation();

Here’s an entire ViewController class example:

using System;

using UIKit;
using CBZSplashView;

namespace Example
{
    public partial class ViewController : UIViewController
    {
        private CBZSplashView.CBZSplashView _splashView;
        protected ViewController(IntPtr handle) : base(handle)
        {
        }

        public override void ViewDidLoad()
        {
            base.ViewDidLoad();

            var icon = UIImage.FromFile("snapchatIcon.png");

            _splashView = new CBZSplashView.CBZRasterSplashView(icon, UIColor.Yellow);

            View.Add(_splashView);

        }

        public override void ViewDidAppear(bool animated)
        {
            base.ViewDidAppear(animated);

            if (_splashView != null)
                _splashView.StartAnimation();
        }
    }
}
