如何在 xamarin.forms 中为日期选择器实现自定义渲染器?
How to implement custom renderer for date picker in xamarin.forms?
我正在所有平台上创建一个应用程序,但主要关注 UWP
但是当我尝试实现日期选择器时,我遇到了一些在 iOS 和 [=36 中运行良好的问题=].有人可以帮我吗?
1- DatePicker 是否有默认设置的最大宽度?目前我在 Grid.Row 的 DatePicker 中添加了 属性 "HorizontalOptions="FillAndExpand"。
代码:
<local:ExtendedDatePicker HorizontalOptions="FillAndExpand" Date="{Binding DOBDate}" Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="9">
</local:ExtendedDatePicker>
2- 我想让角变圆。我可以使用渲染完成 iOS 和 Android。但我不知道如何在 UWP 中制作。我试过以下代码。
代码:
protected override void OnElementChanged(ElementChangedEventArgs<DatePicker> e)
{
base.OnElementChanged(e);
if (Control != null)
{
Control.BorderThickness = new Windows.UI.Xaml.Thickness(5);
Control.Margin = new Windows.UI.Xaml.Thickness(0);
Control.FontFamily = new Windows.UI.Xaml.Media.FontFamily("Roboto");
Control.FontSize = 14;
Control.Padding = new Windows.UI.Xaml.Thickness(0);
}
}
3- 如何设置日期选择器的格式。我尝试使用以下代码,它在 iOS 和 Android 中运行良好。但是,它在 UWP 中保持相同的格式。
<local:ExtendedDatePicker HorizontalOptions="FillAndExpand" Date="{Binding DOBDate}" Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="9">
<DatePicker.Format>dd/MM/yyyy</DatePicker.Format>
</local:ExtendedDatePicker>
第一点可以看到的图片。
求推荐。
Is there any maximum width set by default for DatePicker?

是 DatePicker

MinWidthand
MaxWidth` 属性 创建 DatePickerStyle
以在源代码中编辑样式。对于这种方式,您不需要创建自定义渲染。

在上面的xaml代码的基础上,将合适的CornerRadius
添加到ContentPresenter x:Name="ContentPresenter"
中,就会显示异常
