我正在使用Xamarin.Forms构建我的应用程序。在登录页面中,我有以下布局

<ScrollView>
    <Grid 
        RowSpacing="{StaticResource MediumSpacing}" 
        ColumnSpacing="{StaticResource MediumSpacing}">
        <Grid.RowDefinitions>

            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

在Android模拟器上运行时,我可以在&#34; EntryLine&#34;中输入文字。一切似乎都很好。 但是,当我试图在IOS模拟器上运行它时,文本变得不可用,即只读。基本上在IOS模拟器上,StackLayout内部的所有内容都变成了#ReadOnly&#34; 我也尝试过使用表格&#34; Entry&#34;而不是FormsToolKit.EntryLine,但没有结果。 我在上面的代码中遇到了一个问题,只添加一个&#34; Entry&#34;在xaml和IOS模拟器上的测试工作正常。 已经在Xamarin论坛上提出了相同的问题,但是没有找到任何答案。

答案 0 :(得分:1)

您的<AbsoluteLayout>与您的内容重叠并捕获所有输入事件。您必须尝试将其IsVisible属性设置为false(或InputTransparent属性才能尝试)。至少只要活动指标没有运行。

(如果这不起作用,您可能会尝试使用效果(或自定义渲染器)来处理它,特别是在iOS上设置输入透明度)

(你也可以考虑不把它放在滚动视图中,因为它最终会被滚动掉)
