J'ai la liste des empilements à charger dynamiquement dans XAML Xamarin Forms.Gestion de l'action Développer avec XAML lui-même
Lorsque vous tapez sur stacklayout, les éléments enfants doivent être étendus.
Voici ce que j'ai essayé jusqu'à présent.
<StackLayout Spacing="1">
<StackLayout Style="{StaticResource ExpandableHeaderStyle}">
<Label Text="Spec" FontSize="16" VerticalOptions="CenterAndExpand"/>
<Image Source="{Binding ImageOne}" HorizontalOptions="EndAndExpand" Margin="0,0,12,0">
<Image.GestureRecognizers>
<TapGestureRecognizer Command ="{Binding ExpandViewFlagCommand}" CommandParameter="1"/>
</Image.GestureRecognizers>
</Image>
</StackLayout>
<StackLayout Spacing="0">
<StackLayout.Triggers>
<DataTrigger TargetType="StackLayout" Binding="{Binding Path=ImageOne}" Value="down_Arrow.png">
<Setter Property="IsVisible" Value="False" />
</DataTrigger>
<DataTrigger TargetType="StackLayout" Binding="{Binding Path=ImageOne}" Value="up_Arrow.png">
<Setter Property="IsVisible" Value="True"/>
</DataTrigger>
</StackLayout.Triggers>
<StackLayout Spacing="0" Style="{StaticResource ExpandableViewStyle}">
<Label Text="spec1" FontAttributes="Bold" FontSize="16"/>
<Label Text="spec detail 1" FontSize="14"/>
</StackLayout>
<StackLayout Spacing="0" Style="{StaticResource ExpandableViewStyle}">
<Label Text="spec1" FontAttributes="Bold" FontSize="16"/>
<Label Text="spec detail 1" FontSize="14"/>
</StackLayout>
</StackLayout>
</StackLayout>
<StackLayout Spacing="0">
<StackLayout Style="{StaticResource ExpandableHeaderStyle}">
<Label Text="Features" FontSize="16" VerticalOptions="CenterAndExpand"/>
<Image Source="{Binding ImageTwo}" VerticalOptions="CenterAndExpand" HorizontalOptions="EndAndExpand" Margin="0,0,12,0">
<Image.GestureRecognizers>
<TapGestureRecognizer Command ="{Binding ExpandViewFlagCommand}" CommandParameter="2"/>
</Image.GestureRecognizers>
</Image>
</StackLayout>
<StackLayout Spacing="0">
<StackLayout.Triggers>
<DataTrigger TargetType="StackLayout" Binding="{Binding Path=ImageTwo}" Value="down_Arrow.png">
<Setter Property="IsVisible" Value="False" />
</DataTrigger>
<DataTrigger TargetType="StackLayout" Binding="{Binding Path=ImageTwo}" Value="up_Arrow.png">
<Setter Property="IsVisible" Value="True"/>
</DataTrigger>
</StackLayout.Triggers>
<StackLayout Style="{StaticResource ExpandableViewOneItemStyle}">
<Image Source="bulletIcon.png" HeightRequest="6" WidthRequest="6"/>
<Label Text="feature 1" Style="{StaticResource ExpandableViewChildLabelStyle}" />
</StackLayout>
<StackLayout Style="{StaticResource ExpandableViewOneItemStyle}">
<Image Source="bulletIcon.png" HeightRequest="6" WidthRequest="6"/>
<Label Text="feature 2" Style="{StaticResource ExpandableViewChildLabelStyle}"/>
</StackLayout>
</StackLayout>
<StackLayout Spacing="0">
<StackLayout Style="{StaticResource ExpandableHeaderStyle}">
<Label Text="Applications" FontSize="16" VerticalOptions="CenterAndExpand"/>
<Image Source="{Binding ImageThree}" VerticalOptions="CenterAndExpand" HorizontalOptions="EndAndExpand" Margin="0,0,12,0">
<Image.GestureRecognizers>
<TapGestureRecognizer Command ="{Binding ExpandViewFlagCommand}" CommandParameter="3"/>
</Image.GestureRecognizers>
</Image>
</StackLayout>
<StackLayout Spacing="0">
<StackLayout.Triggers>
<DataTrigger TargetType="StackLayout" Binding="{Binding Path=ImageThree}" Value="down_Arrow.png">
<Setter Property="IsVisible" Value="False" />
</DataTrigger>
<DataTrigger TargetType="StackLayout" Binding="{Binding Path=ImageThree}" Value="up_Arrow.png">
<Setter Property="IsVisible" Value="True"/>
</DataTrigger>
</StackLayout.Triggers>
<StackLayout Style="{StaticResource ExpandableViewOneItemStyle}">
<Image Source="bulletIcon.png" HeightRequest="6" WidthRequest="6"/>
<Label Text="application 1" Style="{StaticResource ExpandableViewChildLabelStyle}"/>
</StackLayout>
<StackLayout Style="{StaticResource ExpandableViewOneItemStyle}">
<Image Source="bulletIcon.png" HeightRequest="6" WidthRequest="6"/>
<Label Text="application 2" Style="{StaticResource ExpandableViewChildLabelStyle}"/>
</StackLayout>
</StackLayout>
</StackLayout>
Je souhaite que le nombre d'empilements à afficher soit dynamique.
Si j'apprends à modifier la visibilité des éléments enfants dans la disposition de la pile sur le tap pour contrôler XAML lui-même, cela suffira également.
Besoin d'aide sur ce produit.
