我到目前为止在Xaml中得到的是：

这是我的Xaml：

<ScrollView>
    <StackLayout>
        <ActivityIndicator IsRunning="{Binding IsFetching}" />
        <ListView ItemsSource="{Binding Events}" Header="2015" Footer="">
            <ListView.ItemTemplate>

                        <ViewCell.View>
                            <StackLayout Orientation="Horizontal" Padding="5" BackgroundColor="White">                                                          
                                <StackLayout>

Answer 1

您可以使用Grid而不是Stack尝试此操作，还可以将RowHeight添加到ListView

<ListView ... RowHeight="55">
 ...
 <ViewCell Height="55">
   <Grid> 
     <Grid.ColumnDefinitions>
       <ColumnDefinition Width="44"/>
       <ColumnDefinition Width="*"/>
       <ColumnDefinition Width="44"/> <!-- for the checkmark -->
     </Grid.ColumnDefinitions>
     <Grid Grid.Column="0">
       <Grid.RowDefinitions>
          <RowDefinition Height="5" />
          <RowDefinition Height="22" />
          <RowDefinition Height="17" />
       </Grid.RowDefinitions>
       <BoxView Grid.Row="0" WidthRequest="44" HeightRequest="5" BackgroundColor="Purple"/>
       <!-- experiment with the vertical alignment to get it right -->
       <Label Grid.Row="1" Text="AUG" .../>
       <Label Grid.Row="2" Text="31" .../>
     </Grid>
<Grid Grid.Column="0">
       <Grid.RowDefinitions>
          <RowDefinition Height="22" />
          <RowDefinition Height="22" /> 
       </Grid.RowDefinitions> 
       <!-- if the vertical alignment doesn't work well add two more rows for top and bottom padding -->
       <Label Grid.Row="0" Text="Relay for life" VerticalOptions="End" .../>
       <Label Grid.Row="1" Text="Hope city" VerticalOptions="Start" .../>
     </Grid>
   </Grid>
 </ViewCell>
