StackLayout two columns each taking half of the space

Question

I am trying to make two labels each taking 50% of the width of the parent (the StackLayout) I tried with Fill, FillAndExpand, StartAndExpand on both Label's but it didn't work:

<StackLayout Orientation="Horizontal">
    <Label Text="AAAAAAAAAAAAAAAAAAAAAAAAA" HorizontalOptions="FillAndExpand" />
    <Label Text="BBBB" HorizontalOptions="FillAndExpand" />
</StackLayout>

Answer 1

Use a Grid instead.

XAML

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <Label Text="AAAAAAAAAAAAAAAAAAAAAAAAA" Grid.Column="0"/>
    <Label Text="BBBB" Grid.Column="1"/>
</Grid>

The two *s mean the columns will have the same width. If you wanted the first column to be twice has big as the second, you could change the first width to 2*.

You can also use EndAndExpand to have the text right-aligned

Answer 2

I know this question was asked last year. But I hope my answer will help other.

Actually with StackLayout you can get the center and cut in half. I love using StackLayout because it has it's own automatic sizing, if you put 3 Views in a StackLayout.Children, the StackLayout will divide these 3 columns at the same exact size.

Here's how I do it in C#:

Content = new StackLayout{
   Orientation = StackOrientation.Horizontal, //Set the StackLayout to start from left to the right
   HorizontalOptions = LayoutOptions.CenterAndExpand, //Expand the layout to full width and center it
   Children = {
      new Label{
         Text = "Test One"//you may add HorizontalOptions in here to if you want the text on the left or right
      },
      new Label{
         Text = "Text Two"
      }
   }
};

Here's how I do it in XAML:

<StackLayout Orientation="Horizontal" HorizontalOptions="CenterAndExpand">
   <Label Text="Test One"></Label>
   <Label Text="Text Two"></Label>
</StackLayout>

I hope this would answer the question on StackLayout :)
