Отображение данных в столбцах Listview вместо строк Xamarin.Forms

Привет, ребята, я пытаюсь отобразить данные в формате столбца, используя список, как показано на рисунке ниже. Как мне добиться этого в Xamarin.Forms или Xamarin.Android.

Отображение столбца

FlexLayout, BindableLayout проверьте официальные документы и выберите один.   -  person EvZ    schedule 12.02.2019

Решение:

Я пишу простой xaml код, чтобы добиться макета на вашей картинке. Я использую Grid:

<ContentPage.Content>
        <Grid x:Name="controlGrid" RowSpacing="2" ColumnSpacing="2">
            <Grid.RowDefinitions>
                <RowDefinition Height="*" />
                <RowDefinition Height="*" />
            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="*" />
            </Grid.ColumnDefinitions>

            <StackLayout Orientation="Vertical"  Grid.Row="0" Grid.Column="0" BackgroundColor="White">
                <StackLayout Orientation="Horizontal">
                    <Label Text="1" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" HorizontalOptions="CenterAndExpand" HeightRequest="40" />
                    <Label Text="TEXT" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" BackgroundColor="Blue" WidthRequest="50" HeightRequest="40"/>
                </StackLayout>
                <BoxView  BackgroundColor="Gray" VerticalOptions="FillAndExpand"/>
            </StackLayout>

            <StackLayout Orientation="Vertical"  Grid.Row="0" Grid.Column="1" BackgroundColor="White">
                <StackLayout Orientation="Horizontal">
                    <Label Text="2" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" HorizontalOptions="CenterAndExpand"  HeightRequest="40" />
                    <Label Text="TEXT" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" BackgroundColor="Blue" WidthRequest="50" HeightRequest="40"/>
                </StackLayout>
                <BoxView   BackgroundColor="Orange" VerticalOptions="FillAndExpand" />
            </StackLayout>

            <StackLayout Orientation="Vertical"  Grid.Row="0" Grid.Column="2" BackgroundColor="White">
                <BoxView   BackgroundColor="Green"  />
                <BoxView   BackgroundColor="Pink" VerticalOptions="FillAndExpand"/>
            </StackLayout>

            <StackLayout Orientation="Vertical"  Grid.Row="0" Grid.Column="3" BackgroundColor="White">
                <BoxView   BackgroundColor="Green" />
                <BoxView   BackgroundColor="Yellow" VerticalOptions="FillAndExpand" />
            </StackLayout>


            <StackLayout Orientation="Vertical"  Grid.Row="1" Grid.Column="0" BackgroundColor="White">
                <StackLayout Orientation="Horizontal">
                    <Label Text="5" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" HorizontalOptions="CenterAndExpand"  HeightRequest="40" />
                    <Label Text="TEXT" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" BackgroundColor="Blue" WidthRequest="50" HeightRequest="40"/>
                </StackLayout>
                <BoxView  BackgroundColor="Gray" VerticalOptions="FillAndExpand"/>
            </StackLayout>

            <StackLayout Orientation="Vertical"  Grid.Row="1" Grid.Column="1"  BackgroundColor="White">
                <BoxView   BackgroundColor="Green" />
                <BoxView   BackgroundColor="Pink" VerticalOptions="FillAndExpand" />
            </StackLayout>

            <StackLayout Orientation="Vertical"  Grid.Row="1" Grid.Column="2" BackgroundColor="White" >
                <Label  Text="777" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" BackgroundColor="Green" HeightRequest="40"/>
                <BoxView   BackgroundColor="Orange" VerticalOptions="FillAndExpand" />
            </StackLayout>

            <StackLayout Orientation="Vertical"  Grid.Row="1" Grid.Column="3" BackgroundColor="White">
                <StackLayout Orientation="Horizontal">
                    <Label Text="8" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" HorizontalOptions="CenterAndExpand"  HeightRequest="40" />
                    <Label Text="TEXT" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" BackgroundColor="Blue" WidthRequest="50" HeightRequest="40"/>
                </StackLayout>
                <BoxView   BackgroundColor="Gold" VerticalOptions="FillAndExpand" />
            </StackLayout>

        </Grid>
    </ContentPage.Content> 

И я установил BackgroundColor="Black" ContentPage так, чтобы между Grids были черные линии.

Вы можете настроить свой собственный макет с помощью changing элементов управления в моих кодах.

Привет, парень, спасибо за все ответы. Я сделал макет с помощью плагина DLToolkit.Forms.Controls.FlowListView.

Список столбцов
