[Question] How to justify text in a label?

[JuanFcoMiranda]

Hi all,

I have a label that displays on more than a line and I would like to justify the text in it (align left and right).

What is the best way to achieve that?

[JuanFcoMiranda]

Nevermind, I figured it out how to do it.

Thanks.

This is the way I did it. I created a new class that inherits from Label, just like this:

public class JustifiedLabel : Label
{
    public static readonly BindableProperty JustifyTextProperty =
        BindableProperty.Create(
            propertyName: nameof(JustifyText),
            returnType: typeof(bool),
            declaringType: typeof(JustifiedLabel),
            defaultValue: false,
            defaultBindingMode: BindingMode.OneWay
        );

    public bool JustifyText
    {
        get => (bool)GetValue(JustifyTextProperty);
        set => SetValue(JustifyTextProperty, value);
    }
}

Then I also had to create a handler:

public class MyJustifiedLabelHandler : LabelHandler
{
    private static readonly IPropertyMapper<JustifiedLabel, MyJustifiedLabelHandler> PropertyMapper = new PropertyMapper<JustifiedLabel, MyJustifiedLabelHandler>(Mapper)
    {
        [nameof(JustifiedLabel.JustifyText)] = MapJustificationMode
    };

    public MyJustifiedLabelHandler() : base(PropertyMapper)
    {
    }

    public static void MapJustificationMode(ILabelHandler handler, ILabel label)
    {
        if (Build.VERSION.SdkInt >= BuildVersionCodes.O) // O == API level 26.0
        {
            handler.PlatformView.JustificationMode = JustificationMode.InterWord;
        }
    }
}

And I had to add this on my MauiProgram.cs:

            builder
            .UseMauiApp<App>()
            .ConfigureMauiHandlers(handlers =>
            {
#if ANDROID
                handlers.AddHandler(typeof(JustifiedLabel), typeof(MyJustifiedLabelHandler));
#endif
            });

And use it just like this:

<controls:JustifiedLabel Text="{x:Static texts:TextsResource.History}" TextType="Text" TextColor="White" FontSize="18" JustifyText="True" />
