Question

我在列表视图上有一个浮动操作按钮。当列表为空或具有较少条目时，浮动操作按钮工作正常，但当列表填满浮动操作按钮时无法点击。在这种情况下，当我尝试单击浮动操作按钮时，单击列表项。

  <AbsoluteLayout>
            <StackLayout AbsoluteLayout.LayoutBounds="0, 0, 1, 1" AbsoluteLayout.LayoutFlags="All">
                <ListView IsPullToRefreshEnabled="{Binding CanExecute}"
                          IsRefreshing="{Binding CanExecute, Converter={StaticResource xyzConverter}}"
                          ItemsSource="{Binding Assessments, Converter={StaticResource abcConverter}}"
                          IsEnabled="{Binding CanExecute}"
                          HasUnevenRows="True"
                          x:Name="ListContent">
                    <ListView.ItemTemplate>
                        <DataTemplate>

尝试此操作，将您的按钮插入StackLayout

<StackLayout>
    <Custom:FloatingActionButtonView 
                AbsoluteLayout.LayoutBounds="1, 1, AutoSize, AutoSize"
                AbsoluteLayout.LayoutFlags="PositionProportional"
                HasShadow="True"
                Size="Normal"
                ImageName="new.png"
                x:Name="FAB"
                ColorNormal="{x:Static Constants:Colors.Primary}"
                Command="{Binding MyCommand}"/>
</StackLayout>
