我有一个StackLayout,ListView我有一个添加按钮,我想在下面显示ListView.但ListView显示许多行未使用.只是空行,这迫使我的按钮显示在页面底部.我VerticalOptions一整天都搞乱了,但不能让行消失.

这是我的XAML代码:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:LiquitMobileApp"
             x:Class="LiquitMobileApp.MainPage"
             Title="Settings"
             >

    <StackLayout BackgroundColor="LightGray">
        <Label Text="Liquit Zones" TextColor="Gray" FontSize="Small" Margin="10"/>
        <StackLayout AbsoluteLayout.LayoutBounds="10,10,10,10">
            <ListView x:Name="UsingZone" SeparatorColor="LightGray" ItemTapped="ZonesList_ItemTapped" RowHeight="60" BackgroundColor="Green"  >
                <ListView.ItemTemplate>
                    <DataTemplate>
                        <ViewCell>
                            <ViewCell.ContextActions>
                                <MenuItem Clicked="OnEdit" Text="Edit" />
                                <MenuItem Clicked="OnDelete" CommandParameter="{Binding .}" Text="Trash" IsDestructive="True" />
                            </ViewCell.ContextActions>
                            <StackLayout Padding="15, 5, 0, 0" Orientation="Horizontal" BackgroundColor="White">
                                <Image Source="{Binding Image}" HorizontalOptions="Start" AbsoluteLayout.LayoutBounds="250.25, 0.25, 50, 50 "/>
                                <StackLayout Orientation="Vertical">
                                <Label Text = "{Binding Name}" FontSize="20" …
