#Xamarin.Forms #表头固定

本文介绍了初学者在Xamarin.Forms中实现固定表头所遇到的困扰，详细讲述了如何避免被ListView.Header误导，并最终通过Grid成功解决问题的方法。通过分享XAML代码，帮助读者理解和应用这一技术。

初学Xamarin 固定表头花了些时间,一开始给ListView.Header误导了,上forums.xamarin.com 也没找到解答.

最后还是通过Grid解决,发一下,怕忘记了.

上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:DataBindingDemos"
             x:Class="DataBindingDemos.SampleSettingsPage"
             Title="Sample Settings"
             BindingContext="{Binding Source={x:Static Application.Current},
                                      Path=Settings}">

    <StackLayout BackgroundColor="{Binding BackgroundColor}"
                 Padding="10"
                 Spacing="10">

        <StackLayout Orientation="Horizontal">
            <Label Text="Name: "
                   VerticalOptions="Center" />

            <Entry Text="{Binding Name}"
                   Placeholder="your name"
                   HorizontalOptions="FillAndExpand"
                   VerticalOptions="Center" />
        </StackLayout>

        <StackLayout Orientation="Horizontal">
            <Label Text="Birth Date: "
                   VerticalOptions="Center" />

            <DatePicker Date="{Binding BirthDate}"
                        HorizontalOptions="FillAndExpand"
                        VerticalOptions="Center" />
        </StackLayout>

        <StackLayout Orientation="Horizontal">
            <Label Text="Do you code in C#? "
                   VerticalOptions="Center" />

            <Switch IsToggled="{Binding CodesInCSharp}"
                    VerticalOptions="Center" />
        </StackLayout>

        <StackLayout Orientation="Horizontal">
            <Label Text="Number of Copies: "
                   VerticalOptions="Center" />

            <Stepper Value="{Binding NumberOfCopies}"
                     VerticalOptions="Center" />

            <Label Text="{Binding NumberOfCopies}"
                   VerticalOptions="Center" />
        </StackLayout>

        <Label Text="Background Color:" />

        <ScrollView VerticalScrollBarVisibility="Always" Orientation="Horizontal"  >
            <StackLayout Orientation="Horizontal"  
                         HorizontalOptions="Center" VerticalOptions="Center" >

                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="30" />
                        <RowDefinition Height="*" />
