如何解决Xamarin-专注于入门且TapGestureRecognizer无法正常工作
<StackLayout Orientation="Horizontal" FlowDirection="RightToLeft" HorizontalOptions="EndAndExpand" Spacing="0">
<StackLayout.GestureRecognizers>
<TapGestureRecognizer Tapped="GoToBasket"></TapGestureRecognizer>
</StackLayout.GestureRecognizers>
<Frame x:Name="frmBasket" CornerRadius="24" Padding="8" BackgroundColor="#FFFFFF">
<StackLayout Orientation="Horizontal">
<Entry x:Name="lblTotalBasket" TextChanged="lblTotalBasket_TextChanged" HorizontalOptions="FillAndExpand" IsReadOnly="True" Text="{Binding TotalPrice,StringFormat='₺{0:0.00}'}" Margin="0,5,0" HorizontalTextAlignment="Center" FontSize="13" VerticalTextAlignment="Center" FontAttributes="Bold" BackgroundColor="#FFFFFF" TextColor="{StaticResource Primary}"></Entry>
<Label x:Name="lblBasketIcon" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" BackgroundColor="Transparent" Text="" FontSize="15" TextColor="{StaticResource Primary}" Margin="8,0" FontFamily="{StaticResource FontAwesomeSolid}"></Label>
</StackLayout>
</Frame>
</StackLayout>
StackLayout TapGestureRecognizer工作,但Entry元素除外。我尝试为Entry元素添加TapGestureRecognizer和Focused属性,但还是没有用。
StackLayout TapGestureRecognizer如何在输入元素点击上工作?
解决方法
如果将IsReadOnly=false
设置为条目,则TapGestureRecognizer将不起作用,因为在点击时它将被聚焦,并且用户可以键入内容。因此,您可以在foucsed
事件中调用方法:
<Entry x:Name="lblTotalBasket" Focused="lblTotalBasket_Focused"/>
在后面的代码中:
private void lblTotalBasket_Focused(object sender,FocusEventArgs e)
{
Console.WriteLine("lblTotalBasket_Focused-entry");
}
如果将IsReadOnly=ture
设置为条目,则TapGestureRecognizer将执行,也可以将TapGestureRecognizer直接添加到条目:
<Entry x:Name="lblTotalBasket" Focused="lblTotalBasket_Focused" HorizontalOptions="FillAndExpand" IsReadOnly="True" Text="{Binding TotalPrice,StringFormat='₺{0:0.00}'}" Margin="0,5,0" HorizontalTextAlignment="Center" FontSize="13" VerticalTextAlignment="Center" FontAttributes="Bold" BackgroundColor="#FFFFFF">
<Entry.GestureRecognizers>
<TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped"></TapGestureRecognizer>
</Entry.GestureRecognizers>
</Entry>
在后面的代码中:
private void TapGestureRecognizer_Tapped(object sender,EventArgs e)
{
Console.WriteLine("TapGestureRecognizer_Tapped-entry");
}
更新:
在Android中,您还需要设置isEnable = false
才能使TapGestureRecognizer
工作:
<Entry x:Name="lblTotalBasket" IsEnabled="False"/>
