This is a small plugin to allow Xamarin Forms apply different language on the fly

Support

• Android
• iOS

How to use

1. Install the plugin to your Xamarin Form project (.net standard project only)

Install-Package Plugin.XF.MultiLanguage

2. Create your string resources file and define key and value

StringRes.resx         //Default
StringRes.es.resx      //Spanish
StringRes.zh.resx      //Chinese

3. Init the library in App.cs with your ResourceManager

    public App()
        {
            InitializeComponent();
            Plugin.XF.MultiLanguage.StringLoader.Instance.Init(StringRes.ResourceManager);
            MainPage = new MainPage();
        }

4. Use in XAML

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:d="http://xamarin.com/schemas/2014/forms/design"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:multiLang="clr-namespace:Plugin.XF.MultiLanguage;assembly=Plugin.XF.MultiLanguage"
             mc:Ignorable="d"
             x:Class="SampleApp.MultiLangage.MainPage">
      <!-- Replace {ResourceKey} to the key, for example, [Hello].Value-->
      <Label  Text="{Binding [{ResourceKey}].Value, Source={x:Static multiLang:StringLoader.Instance}}" 
           HorizontalOptions="Center"
           VerticalOptions="CenterAndExpand"/>
           
</ContentPage>

5. Use in C#

//Replace ResourceKey to to key, for example, Hello
StringLoader.Instance.GetString("ResourceKey").Value;

Change App language

1. Call this below to change the app language in runtime

  Plugin.XF.MultiLanguage.StringLoader.Instance.SetCultureInfo(new CultureInfo(languageCode));

Important to know

As the plugin does not save the language preference, the app should set the language again while launching. Otherwise, it will take DeviceUICultureInfo as the culture info.

Reference

LCID language code in HEX
