Tizen XAML App Template

1) Create project

• Select 'Tizen XAML App' template on 'New project'.

• Select only wearable device at Tizen project wizard.

  

• Search Xamarin.Forms NuGet package and install latest version (supports version 3.1.0.583944 and higher) via NuGet package manager. Package source is Nuget.org.

  

• Search Tizen.Wearable.CircularUI NuGet package and install latest version via NuGet package manager. Package source is Nuget.org.

  

• Install Tizen.Wearable.CircularUI NuGet at portable class library (PCL) project.

  

2) Insert CircularUI control code

• Remove SampleCircleApp.cs that is generated automatically at PCL.

• Add App.xaml and App.xaml.cs using add item.

• In App.xaml file, remove all of the template code and replace it with the following code. This code defines the user interface for the page:

  • xmlns:w=clr-namespace:Tizen.Wearable.CircularUI.Forms : w prefix means Tizen.Wearable.CircularUI.Forms namespace.
  • <w:CirclePage> : CirclePage derive from Xamarin.Forms.Page. This Page content area has Label and Button.
  • <w:CirclePage.CircleSurfaceItems> : CircleSliderSurfaceItem attached for CircleSurfaceItem of CirclePage.

  • RotaryFocusObject is set reference of the slider. CircleSliderSurfaceItem has rotary focus. CircleSliderSurfaceItem can receive a Rotary Event from the wearable device's bezel interaction.

    For more information, see CirclePage guide.

App.xaml file

                    x:Name="page"
                    NavigationPage.HasNavigationBar="False"
                    RotaryFocusObject="{x:Reference slider}">
                    <w:CirclePage.Content>
                        <StackLayout
                            HorizontalOptions="Center"

                            VerticalOptions="Center">
                            <Label HorizontalTextAlignment="Center" Text="Welcome to Xamarin Forms!" />
                            <Button Clicked="OnButtonClicked" Text="show toast" />
                        </StackLayout>
                    </w:CirclePage.Content>
                    <w:CirclePage.CircleSurfaceItems>
                        <w:CircleSliderSurfaceItem
                            x:Name="slider"
                            Increment="0.5"
                            IsVisible="True"
                            Maximum="15"
                            Minimum="0"
                            Value="3" />
                    </w:CirclePage.CircleSurfaceItems>
                </w:CirclePage>
            </x:Arguments>
        </NavigationPage>
    </Application.MainPage>
</Application>

• In App.xaml.cs, remove all of the template code and replace it with the following code:
  • OnButtonClicked is an event handler of Button Clicked event. The following code simply displays Toast popup during three seconds:

App.xaml.cs file

using Tizen.Wearable.CircularUI.Forms;
using System;

using Xamarin.Forms;
using Xamarin.Forms.Xaml;

namespace SampleCircleApp
{
    [XamlCompilation(XamlCompilationOptions.Compile)]
    public partial class App : Application
    {
        public App()
        {
            InitializeComponent();
        }

        public void OnButtonClicked(object sender, EventArgs e)
        {
            Toast.DisplayText("Toast popup", 3000);
        }
    }
}

• For initializing CircularUI instance, insert FormsCircularUI.Init() code in the Main method in SampleCircleApp.Tizen.Wearable.cs. You must import Tizen.Wearable.CircularUI.Forms.Renderer with using directives.

SampleCircleApp.Tizen.Wearable.cs file

using Tizen.Wearable.CircularUI.Forms.Renderer;


        static void Main(string[] args)
        {
            var app = new Program();
            global::Xamarin.Forms.Platform.Tizen.Forms.Init(app);
            FormsCircularUI.Init();  //must insert this initialize code
            app.Run(args);
        }

2. Build and launch your application.

• Build the solution

  • In the Visual Studio menu, select Build > Build Solution.
  • In the Solution Explorer view, right-click the solution name and select Build.

• Launch Tizen Emulator

  • Click Launch Tizen Emulator button, as displayed in the following image:

    

• For Windows OS, copy the application tpk file from the project binary path to sdb tool path.

  • SampleCircleApp tpk: The file is located in ProjectPath\SampleCircleApp.Tizen.Wearable\bin\Debug\tizen40\org.tizen.example.SampleCircleApp.Tizen.Wearable-1.0.0.tpk.
  • Project path: To locate the project path, in the Solution Explorer view, right-click the solution name and click open folder in file explorer.
  • sdb tool: This is located in c:\tizen\tools\sdb.exe

• For Windows OS, launch Tizen Sdb Command Prompt (Tool > Tizen > Tizen Sdb Command Prompt). For Linux, you can use sdb command directly in your project path.

• Install your app with sdb command

  sdb install org.tizen.example.SampleCircleApp.Tizen.Wearable-1.0.0.tpk
  

• Launch wearable emulator to verify the application
