在xamarin foms xaml中居中对齐堆栈内容

我正在尝试将堆栈布局中心与网格单元对齐，但无法实现，请查看此代码，并告诉我是否进行了任何错误的对齐

我想在stacklayout中水平和垂直放置两个标签，堆栈应该在网格单元中填充和展开

请你方提出一些建议

谢谢，

尝试使用此代码。在这两种布局中，我使用了网格代替stacklayout。它会很好用的

        <Grid>

            <RowDefinition Height="Auto"></RowDefinition>
          </Grid.RowDefinitions>

          <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"></ColumnDefinition>
            <ColumnDefinition Width="*"></ColumnDefinition>
