Xaml Xamarin表单-按钮边距

我有以下Xaml：

<Grid Padding="0">
        <Grid.ColumnDefinitions>
          <ColumnDefinition Width="*"></ColumnDefinition>
          <ColumnDefinition Width="*"></ColumnDefinition>
          <ColumnDefinition Width="*"></ColumnDefinition>
        </Grid.ColumnDefinitions>
        <ContentView Grid.Column="0">
          <Button Text="SomeText" 
                  BorderRadius="0" Grid.Column="0" 
                  BorderWidth="0"
                  BackgroundColor="Red"
                  TextColor="White"
                  ></Button>
        </ContentView>
        <ContentView Grid.Column="0">
          <Button Text="SomeText" 
                  BorderRadius="0" Grid.Column="0" 
                  BorderWidth="0"
                  BackgroundColor="Blue
                  TextColor="White"
                  ></Button>
        </ContentView>
        <ContentView Grid.Column="0">
          <Button Text="SomeText" 
                  BorderRadius="0" Grid.Column="0" 
                  BorderWidth="0"
                  BackgroundColor="Green
                  TextColor="White"
                  ></Button>
        </ContentView>
      </Grid>

渲染时，每个按钮之间都有间隙。我想让按钮按一下。但我在任何地方都看不到任何填充或边距设置？

试试：

<Grid Padding="0" ColumnSpacing="0" RowSpacing="0">

是否需要在每个屏幕上显示ContentVIew？如果我没记错的话，它默认设置了一个填充。或者Button呢，是否有一个默认的模板给它留有空白？另外，您不需要在子元素上有Grid.*声明，只需要在其父元素上有Grid.*声明。Grid对象有

行间距

和

列间距

属性，您可以将其设置为cero；这很有效，谢谢你。真不敢相信我自己找不到那个信息！
