Visual State Manager 和 Entry && 触发键盘 xamarin 表单的问题

Question

在第一部分中，我使用网格的代码，我必须在输入字段上点击 2 次才能触发键盘，而在第二部分没有网格，仅从第一次开始，我不明白为什么

  <ContentPage.Content>
            <Grid  VerticalOptions="FillAndExpand">
                <Grid.ColumnSpacing>
                    <OnIdiom x:TypeArguments="x:Double"
                 Phone="0"
                 Tablet="40"/>
                </Grid.ColumnSpacing>
                <Grid.RowSpacing>
                    <OnIdiom x:TypeArguments="x:Double"
                 Phone="20"
                 Tablet="20"/>
                </Grid.RowSpacing>
                <Grid.Padding>
                    <OnIdiom x:TypeArguments="Thickness"
                 Phone="10, 30, 10, 30"
                 Tablet="20, 20, 20, 0"/>
                </Grid.Padding>

                <Grid.RowDefinitions>
                    <RowDefinition Height="3*"/>
