如何禁用 UWP 应用程序的缩放

Question

我正在设计 uwp 应用程序。我的电脑分辨率是 1920 x 1080，100% 比例。所有元素都是正常布局。但是当运行应用程序在 1920 x 1080、125% 比例的屏幕上显示时，元素不在正确的位置，所有元素都大了 1.25 倍。

那么如何在所有分辨率下禁用缩放，或者有什么解决办法吗？

Answer 1

我给你一个简单的例子，我在其中展示了两个按钮和一个网格，你可以运行在任何分辨率下，左右手边的按钮总是保持在相同的位置，网格会相应地改变分辨率大小

   <Grid HorizontalAlignment="Stretch"  Margin="0,0,0,0" VerticalAlignment="Stretch" >
        <Grid.RowDefinitions>
            <RowDefinition Height="150"/>
            <RowDefinition Height="169*"/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="150"/>
            <ColumnDefinition Width="113*"/>
            <ColumnDefinition Width="150"/>
        </Grid.ColumnDefinitions>
        <Button Content="Button" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="10,55,10,40" />
        <Button Content="Button" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="10,55,10,40" Grid.Column="2" />
        <Grid Grid.Column="1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" BorderBrush="Black" BorderThickness="2" Grid.RowSpan="2"/>
    </Gid>

您的代码示例

   <Grid HorizontalAlignment="Stretch"  Margin="0,0,0,0" VerticalAlignment="Stretch" >
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="945"/>
            <ColumnDefinition Width="945"/>
        </Grid.ColumnDefinitions>
        <TextBlock Text="Color"
            Margin="117, 84, 0, 0"
            FontSize="48"/>
        <Button Grid.Row="1" Content="Red" Width="500" Height="80" HorizontalAlignment="Stretch"  VerticalAlignment="Stretch" 
                Margin="445 30 0 0"
                />
        <Button Grid.Row="1" Grid.Column="1" Content="Yellow" Width="500" Height="80" 
                Margin="0 30 445 0"
                HorizontalAlignment="Center" VerticalAlignment="Center"/>


        <Grid Grid.Row="2" Grid.ColumnSpan="2"
            Margin="84 40 84 0" HorizontalAlignment="Stretch" 
              VerticalAlignment="Stretch" BorderBrush="Black" BorderThickness="2"/>
    </Grid>
