如何以Xamarin形式滚动框架？

Question

我已经用Xamarin Forms设计了一页，使用了StackLayout和Frame Combination。 但是ContentPage不会滚动。 页面上未显示最后一帧。如何管理滚动？ 另外Listview自动添加滚动，我不想在Listview中显示滚动。 怎么可能 我的代码是：

<ContentPage.Content>
    <StackLayout >
        <StackLayout>
            <Frame>
                <StackLayout>
                    <Grid >
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="0"/>
                            <ColumnDefinition Width="40*"></ColumnDefinition>
                            <ColumnDefinition Width="60*"></ColumnDefinition>
                            <ColumnDefinition Width="0"/>
                        </Grid.ColumnDefinitions>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="0"></RowDefinition>
                            <RowDefinition Height="Auto"></RowDefinition>
                            <RowDefinition Height="Auto"></RowDefinition>
                            <RowDefinition Height="Auto"></RowDefinition>
                            <RowDefinition Height="Auto"></RowDefinition>
                            <RowDefinition Height="0"></RowDefinition>
                        </Grid.RowDefinitions>

Answer 1

以此替换您的代码

<ContentPage.Content>
   <ScrollView x:Name="MainScroll" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">
       <StackLayout >
          //Your main StackLayout code
       </StackLayout>
     </ScrollView>
</ContentPage.Content>

对于基于内容的列表视图展开，将以下代码放入xaml.cs页面的构造函数中。

设置您的ListView名称和特定的RowHeight。

MyListView.PropertyChanged += (object sender, System.ComponentModel.PropertyChangedEventArgs e) =>
            {
                if (e.PropertyName == "ItemsSource")
                {
                    try
                    {
                        if (MyListView.ItemsSource != null)
                        {
                            var tmp = (IList)MyListView.ItemsSource;
                            MyListView.HeightRequest = tmp.Count * MyListView.RowHeight;
                        }
                    }
                    catch (Exception ex)
                    {
                        ex.Track();
                    }
                }
            };
