小编Nat*_*n N的帖子

我在Xamarin表单应用程序中使用Prism ListView，每个Listitem都有2个图像，一个编辑图像和一个删除图像。

我已经TapGesturesRecognizers在这2张图片上使用了，并DelegateCommands为它们绑定了_ TapGestureRecognizers。但是，这些DelegateCommands不会被调用。

提前致谢

这是我的XAML代码

<ListView x:Name="lstAddress" HasUnevenRows="True" SeparatorVisibility="None" ItemsSource="{Binding ListItems}" CachingStrategy="RecycleElement" >
        <ListView.Behaviors>
            <b:EventToCommandBehavior EventName="ItemTapped"
          Command="{Binding ListItemSelectCommand}"  EventArgsParameterPath="Item"/>
        </ListView.Behaviors>
        <ListView.ItemTemplate>
            <DataTemplate>
                <ViewCell>
                    <StackLayout Orientation="Horizontal">
                        <Label  Text="{Binding Description}" FontSize="15" TextColor="#959595">
                        </Label>
                        <Image Source="Edit.png"  HeightRequest="50" WidthRequest="50" IsVisible="{Binding ShowEdit}">
                            <Image.GestureRecognizers>
                                <TapGestureRecognizer Command ="{Binding EditAddressCommand}"></TapGestureRecognizer>
                            </Image.GestureRecognizers>
                        </Image>
                        <Image Source="Delete.png" ClassId="{Binding ListID}" HeightRequest="30" WidthRequest="30" IsVisible="{Binding ShowIcon}">
                            <Image.GestureRecognizers>
                                <TapGestureRecognizer Command ="{Binding DeleteAddressCommand}"></TapGestureRecognizer>
                            </Image.GestureRecognizers>
                        </Image>
                    </StackLayout>
                </ViewCell>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>
