Question

我有这个代码。我想用<Grid>替换它并简化它。有没有办法可以做到这一点并实现GestureRecognizer？

<ViewCell x:Name="cfs">
    <StackLayout VerticalOptions="CenterAndExpand" Padding="20,0,20,0">
       <StackLayout.GestureRecognizers>
          <TapGestureRecognizer Command="{Binding OpenPickerCommand}" CommandParameter="{x:Reference cfsPicker}" NumberOfTapsRequired="1" />
       </StackLayout.GestureRecognizers>
       <StackLayout Orientation="Horizontal" VerticalOptions="CenterAndExpand">
          <StackLayout HorizontalOptions="StartAndExpand" VerticalOptions="Center">
             <local:LabelBodyRendererClass Text="Card Front Side" YAlign="Center" XAlign="Center" />
          </StackLayout>
          <StackLayout HorizontalOptions="EndAndExpand" Orientation="Horizontal">
             <Picker x:Name="cfsPicker" IsVisible="false" SelectedIndexChanged="cfsOnPickerSelectedIndexChanged" ItemsSource="{Binding Languages}"></Picker>
             <local:LabelBodyRendererClass x:Name="cfsLabel" />
             <Label Text="{x:Static local:FontAwesome.FAAngleRight}" FontFamily="FontAwesome" TextColor="Gray" XAlign="Center" HorizontalOptions="EndAndExpand" />
          </StackLayout>
       </StackLayout>
    </StackLayout>

您是否尝试过Grid.GestureRecognizers ....

<Grid>
    <Grid.GestureRecognizers>
        <TapGestureRecognizer Command="{Binding OpenPickerCommand}" CommandParameter="{x:Reference cfsPicker}" NumberOfTapsRequired="1" />
    </Grid.GestureRecognizers>
</Grid>

当我需要GestureRecognizer时，有没有办法可以使用<stacklayout>替换<grid>？
