Xamarin.Forms：用户界面在UWP中正常工作，但不在Android部件上

问题描述：

美好的一天每个人。我目前正在开发一个简单的程序，使用户能够对员工进行CRUD记录。Xamarin.Forms：用户界面在UWP中正常工作，但不在Android部件上

我能够从ASP.NET Web应用程序检索创建的数据并将其显示在我的程序的UWP部分。但是，每当我在Android上运行时，它都无法正常工作。意思是，一些菜单和按钮没有被显示。

我在Xamarin.Forms Portable中编写了所有这些代码。

这是我的菜单页面的代码，应该在两个平台上正确显示。如果你想看更多的代码，请让我知道。非常感谢。

下面是1.截图）UWP和2）机器人。

能否请你告诉UWP的VS Android的截图，所以我们可以得到的区别是什么清晰的画面。 –

@AdamPedley对不起。我添加了先生的截图。 –

答

你可以用它代替StackLayout网格。这在当前情况下最适合。

例如： -

<Grid> 
<Grid.RowDefinitions> 
    <RowDefinition Height="*" /> 
    <RowDefinition Height="*" /> 
    <RowDefinition Height="*" /> 
    <RowDefinition Height="*" /> 
    <RowDefinition Height="*" /> 
    <RowDefinition Height="*" /> 
    <RowDefinition Height="*" /> 
    <RowDefinition Height="*" /> 
</Grid.RowDefinitions> 
<Grid.ColumnDefinitions> 
    <ColumnDefinition Width="*" /> 
</Grid.ColumnDefinitions> 

<Image x:Name="sales" Source="SomeTime1.png" Grid.Column="0" Grid.Row="0"> 
    <Image.GestureRecognizers> 
     <TapGestureRecognizer Tapped="SalesTapGestureRecognizer_OnTapped" NumberOfTapsRequired="1" /> 
    </Image.GestureRecognizers> 
</Image> 

<Image x:Name="sales" Source="SomeTime2.png" Grid.Column="0" Grid.Row="1"> 
    <Image.GestureRecognizers> 
     <TapGestureRecognizer Tapped="PersonnelTapGestureRecognizer_OnTapped" NumberOfTapsRequired="1" /> 
    </Image.GestureRecognizers> 
</Image>
