Xamarin 在 Visual Studio 2022 中表单 Android => 图像按钮点击手势识别器不起作用

Question

My xaml is:

        <ContentPage.Resources>
        <ResourceDictionary>
            <DataTemplate x:Key="displayItemTemplate">
                <StackLayout>
                    <Frame  CornerRadius="3" HasShadow="False" Margin="10,2" Padding="5,0"
                            BorderColor="{Binding BindingContext.AppSettings[MPLVItemFrameBorderColor], Source={x:Reference this}}"
                            BackgroundColor="{Binding BindingContext.AppSettings[MPLVItemFrameBackgroundColor], Source={x:Reference this}}">
                        <StackLayout Orientation="Horizontal">
                            <BoxView BackgroundColor="Transparent" Color="{Binding Status, Converter={StaticResource NoteStatusToColorConverter}}" Margin="4" HeightRequest="32" WidthRequest="32" CornerRadius="5">
                                <BoxView.GestureRecognizers>
                                    <TapGestureRecognizer Command="{Binding Source={x:Reference this}, Path=BindingContext.NoteStatusSwitchCommand}" CommandParameter="{Binding .}"/>
                                </BoxView.GestureRecognizers>
                            </BoxView>
                            <Label BackgroundColor="Transparent" Text="{Binding Description}" TextDecorations="{Binding Status, Converter={StaticResource NoteStatusConverter}}" HorizontalOptions="FillAndExpand" VerticalTextAlignment="Center" HorizontalTextAlignment="Start">
                                <Label.GestureRecognizers>
                                    <TapGestureRecognizer NumberOfTapsRequired="2" Command="{Binding Source={x:Reference this}, Path=BindingContext.NoteEditCommand}" CommandParameter="{Binding .}"/>
                                </Label.GestureRecognizers>
                            </Label>
                            <ImageButton BackgroundColor="Transparent" Source="{Binding ItemImagePath, Converter={StaticResource ImagePathToImageSourceConverter}}" HeightRequest="32" WidthRequest="32"><!--Command="{Binding Source={x:Reference this}, Path=BindingContext.ItemImage1TapCommand}" CommandParameter="{Binding .}">-->
                                <ImageButton.GestureRecognizers>
                                    <TapGestureRecognizer NumberOfTapsRequired="1" Command="{Binding Source={x:Reference this}, Path=BindingContext.ItemImage1TapCommand}" CommandParameter="{Binding .}"/>
                                    <!--<TapGestureRecognizer NumberOfTapsRequired="2" Command="{Binding Source={x:Reference this}, Path=BindingContext.ItemImage2TapsCommand}" CommandParameter="{Binding .}"/>-->
                                </ImageButton.GestureRecognizers>
                            </ImageButton>
                            <ImageButton BackgroundColor="Transparent" Source="NoteDelete.png" HeightRequest="32" WidthRequest="32"
                                         Command="{Binding Source={x:Reference this}, Path=BindingContext.NoteDeleteCommand}" CommandParameter="{Binding .}"/>
                        </StackLayout>
                    </Frame>
                </StackLayout>
            </DataTemplate>
            <DataTemplate x:Key="emptyItemTemplate">
                <Grid/>
            </DataTemplate>

ImageButton中的TapGestureRecognizer命令永远不会被调用。
如果我删除识别器并在ImageButton中添加一个普通的Command属性，则该命令将被调用。
我在这个2天，尝试多个测试和互联网浏览。有谁能帮帮我吗?
注意:按键在中工作良好:
.BoxView
.Label控制
当我ImageButton置评。gestererecogizers，并把Command直接作为ImageButton的属性。

! !找到解决方案了!!
我在StackLayout中包含了ImageButton，在这个StackLayout中包含了Recognizers，在ImageButton中没有更多。
看来问题解决了。

您需要做的就是将ImageButton移动到StackLayout中。你必须确保Recognizers在你创建的StackLayout里面而不是在ImageButton里面
