Question

我一直为此苦苦挣扎。我有一个简单的列表视图，该视图使用数据模型提取数据。我要做的就是在背景中放一个与屏幕大小相同的图像

<ContentPage Padding="0,-20,0,0" xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="xxxxxxxx.Pages.PrayersByCategory">
<ContentPage.Content>
    <ListView RowHeight="55"  x:Name="lv_prayers_categories_page" VerticalOptions="FillAndExpand" HasUnevenRows="false" SelectedItem="Handle_ItemSelected" BackgroundColor="Transparent" SeparatorVisibility="None">
        <ListView.ItemTemplate>
            <DataTemplate>
                <ViewCell>
                        <Grid x:Name="cellGrid" Padding="15">
                        <Grid.ColumnDefinition></Grid.ColumnDefinition>
                        <Label x:Name="lblPrayerCategory" Text = "{Binding prayerCategory}" FontSize="16" Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2"/>
                        <Label x:Name="lblPrayerCount" Text = "{Binding prayerCategoryID}" FontSize="16" Grid.Row="0" Grid.Column="2" Grid.ColumnSpan="2"/></Grid></ViewCell>        
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>
</ContentPage.Content>

如果列表视图填充了页面，则可以设置 ContentPage 背景颜色：

    <ContentPage Padding="0,-20,0,0" 
    xmlns="http://xamarin.com/schemas/2014/forms" 
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" 
    x:Class="xxxxxxxx.Pages.PrayersByCategory"
    BackgroundImage="star_outline.png">
