在 Xamarin Forms 中,我想实现一个水平列表视图(如下图所示)。通过旋转这是可能的,但我无法更改行宽。是否也有可能让第二个布局在第一个布局下开始?
提前致谢!
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="Recipe.Pages.SearchPage"
Title="Search">
<ContentPage.Content>
<StackLayout Spacing="5" x:Name="layout" Orientation="Vertical" >
<StackLayout x:Name="layoutButtons" HorizontalOptions="FillAndExpand" Orientation="Horizontal" Spacing="5" BackgroundColor="Red">
<Button x:Name="btn1" BackgroundColor="White" Image="@drawable/scan" />
<Button x:Name="btn2" BackgroundColor="White" Image="@drawable/menu" />
<Button x:Name="btn3" BackgroundColor="White" Image="@drawable/search" />
</StackLayout>
<StackLayout x:Name="layoutList" >
<ListView x:Name="listView" Rotation="270" RowHeight="75" >
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout BackgroundColor="#eee" Orientation="Vertical" >
<StackLayout Orientation="Horizontal" >
<Button BackgroundColor="White" Rotation="90" Image="{Binding Recipe}" />
</StackLayout>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
</StackLayout>
</ContentPage.Content>
</ContentPage>
EDIT我还尝试在列表视图中使用网格。有同样的问题。
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="Recipe.Pages.SearchPage"
Title="Search">
<ContentPage.Content>
<StackLayout Spacing="5" x:Name="layout" Orientation="Vertical" >
<StackLayout x:Name="layoutButtons" HorizontalOptions="FillAndExpand" Orientation="Horizontal" Spacing="5" BackgroundColor="Red">
<Button x:Name="btn1" BackgroundColor="White" Image="@drawable/scan" />
<Button x:Name="btn2" BackgroundColor="White" Image="@drawable/menu" />
<Button x:Name="btn3" BackgroundColor="White" Image="@drawable/search" />
</StackLayout>
<StackLayout x:Name="layoutList" >
<ListView x:Name="listView" Rotation="270" RowHeight="75" >
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="75" />
</Grid.ColumnDefinitions>
<Button Grid.Column="0" BackgroundColor="White" Rotation="90" Image="{Binding Recipe}" />
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
</StackLayout>
</ContentPage.Content>
</ContentPage>
我也面临同样的问题。我使用下面的 xaml 代码来管理高度和宽度ListView
.
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="VCRoom.HorizontalScroll">
<ContentPage.Content >
<RelativeLayout>
<ListView x:Name="TestListView"
RowHeight="80"
Rotation="270"
RelativeLayout.XConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width, Factor=0.5, Constant=-40}"
RelativeLayout.YConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width, Factor=-0.5, Constant=40}"
RelativeLayout.WidthConstraint="{ConstraintExpression Type=Constant, Constant=80}"
RelativeLayout.HeightConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width, Factor=1}"
>
</ListView>
</RelativeLayout>
</ContentPage.Content>
</ContentPage>
Change RowHeight
and Constant
in XConstraint
and YConstraint
管理水平的宽度和高度ListView
因此。
仅供参考下面是我用来填充的自定义单元格ListView
项目。我在每个列表项中显示垂直标签。
<?xml version="1.0" encoding="UTF-8"?>
<ViewCell xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="VCRoom.TestCell">
<ViewCell.View>
<StackLayout Orientation="Horizontal" HorizontalOptions="End" VerticalOptions ="Center">
<Label Rotation="90" Text="{Binding Day}" TextColor="#000000" HorizontalOptions="StartAndExpand" VerticalOptions="Start"/>
<Label Rotation="90" Text="{Binding mDate}" TextColor="#000000" HorizontalOptions="StartAndExpand" VerticalOptions="Start"/>
</StackLayout>
</ViewCell.View>
</ViewCell>
希望这对未来的用户有所帮助。
