如何加宽这些 Picker 控件并将它们右对齐?
How do I widen these Picker controls and align them on the right?
我脑子里有很多问题,我意识到有更好的方法可以完成您将看到的大部分内容。随着我学习的时间。
在此特定实例中,我创建了一个带有一些控件的 Frame
元素:
<Frame Grid.Column="2" Grid.Row="0" HasShadow="False" BorderColor="Black" Margin="10">
<StackLayout Spacing="10" >
<StackLayout Padding="10" BackgroundColor="DarkSalmon" HorizontalOptions="FillAndExpand">
<Label Text="Report Settings"/>
</StackLayout>
<Label Text="Starting month:"/>
<Picker Title="Select month">
<Picker.ItemsSource>
<x:Array Type="{x:Type x:String}">
<x:String>January</x:String>
<x:String>February</x:String>
<x:String>March</x:String>
<x:String>April</x:String>
<x:String>May</x:String>
<x:String>June</x:String>
<x:String>July</x:String>
<x:String>August</x:String>
<x:String>September</x:String>
<x:String>October</x:String>
<x:String>November</x:String>
<x:String>December</x:String>
</x:Array>
</Picker.ItemsSource>
</Picker>
<StackLayout Orientation="Horizontal">
<Label Text="Number of months:"/>
<Picker Title="Number of months" HorizontalOptions="End" HorizontalTextAlignment="Start">
<Picker.ItemsSource>
<x:Array Type="{x:Type x:String}">
<x:String>1</x:String>
<x:String>2</x:String>
<x:String>3</x:String>
<x:String>4</x:String>
<x:String>5</x:String>
<x:String>6</x:String>
<x:String>7</x:String>
<x:String>8</x:String>
<x:String>9</x:String>
<x:String>10</x:String>
<x:String>11</x:String>
<x:String>12</x:String>
</x:Array>
</Picker.ItemsSource>
</Picker>
</StackLayout>
<StackLayout Orientation="Horizontal">
<Label Text="Number of publishers to visit each month:"/>
<Picker Title="Number of publishers" HorizontalOptions="End">
<Picker.ItemsSource>
<x:Array Type="{x:Type x:String}">
<x:String>1</x:String>
<x:String>2</x:String>
<x:String>3</x:String>
<x:String>4</x:String>
<x:String>5</x:String>
</x:Array>
</Picker.ItemsSource>
</Picker>
</StackLayout>
<Label Text="Starting publisher:"/>
<Picker Title="Number of publishers">
<Picker.ItemsSource>
<x:Array Type="{x:Type x:String}">
<x:String>Name 1</x:String>
<x:String>Name 2</x:String>
<x:String>Name 3</x:String>
<x:String>Name 4</x:String>
<x:String>Name 5</x:String>
</x:Array>
</Picker.ItemsSource>
</Picker>
</StackLayout>
</Frame>
我在 Xamarin 4.8 中使用 Visual Studio for Mac。想使用 5.x 但我得到异常 运行 软件。项目输出为 MacOS。这是我目前看到的:
我想让两个插入 (Number ...) Picker
对象稍宽一些并与右侧对齐。然后标签可以弥补松弛。此刻是错开的,picker变窄了。
我尝试使用 HorizontalOptions
但失败了。
感谢指导。
根据评论中的建议,我能够像这样调整我的 XAML 代码:
<Picker Title="Number of publishers" HorizontalOptions="EndAndExpand" WidthRequest="75">
<Picker.ItemsSource>
<x:Array Type="{x:Type x:String}">
<x:String>1</x:String>
<x:String>2</x:String>
<x:String>3</x:String>
<x:String>4</x:String>
<x:String>5</x:String>
</x:Array>
</Picker.ItemsSource>
</Picker>
我需要使用:
HorizontalOptions
WidthRequest
