愿你出走半生,归来仍是少年！ 

环境：.NET 7

        在开发中，最常用的弹窗之一表示确认弹窗，为了减少重复的开发工作，所以需要基于Popup进行封装。

1.布局

        分为标题、确认内容、按钮三个区域，都是可供调整的。

<?xml version="1.0" encoding="utf-8" ?>
<toolkit:Popup xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MauiLib.Utility.Controls.Popups.ConfirmPopup"
             xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"
             x:Name="popup" 
                xmlns:config="clr-namespace:MauiLib.Utility.Configs;assembly=MauiLib.Utility"
             Color="Transparent" 
               
              >

    <VerticalStackLayout x:Name="outLyt"     BackgroundColor="Transparent">

        <Border  WidthRequest="400"   BackgroundColor="White"  StrokeThickness="1"  StrokeShape="RoundRectangle 10,10,10,10"  HorizontalOptions="Center">

            <VerticalStackLayout  >

                <Label x:Name="lbTitle" Text="标题" HorizontalOptions="Center" Padding="0,10,0,10" FontSize="18"/>

                <Border Stroke="{Static config:ThemeConfig.SubTitle}" BackgroundColor="{Static config:ThemeConfig.SubTitle}" WidthRequest="400" StrokeThickness="0.2"  />

                <Label x:Name="lbContent" 
                       Margin="15" 
                       FontSize="14" 
                       MinimumHeightRequest="100" 
                       VerticalOptions="CenterAndExpand" 
                       Text="确认内容"/>

                <FlexLayout AlignContent="Center" AlignItems="Stretch" Direction="Row">
                    <Button x:Name="btnCancle" 
                      BackgroundColor="Transparent" 
                      TextColor="Black"  
                      FlexLayout.Grow="1"  
                      BorderColor="{Static config:ThemeConfig.SubTitle}"
                      BorderWidth="0.2"
                      CornerRadius="0"   
                      Text="取消" 
                      Clicked="btnCancle_Clicked" />

                    <Button x:Name="btnOk"   
                        BackgroundColor="Transparent" 
                        TextColor="Black"   
                        FlexLayout.Grow="1"  
                        BorderColor="{Static config:ThemeConfig.SubTitle}"
                        BorderWidth="0.2"
                        CornerRadius="0"
                        Text="确认" 
                        Clicked="btnOk_Clicked"/>





                </FlexLayout>


            </VerticalStackLayout>
        </Border>
    </VerticalStackLayout>
</toolkit:Popup>

2.代码

        通过两个不同的构造函数，实现只确认和可选择确认的两种弹窗对象。然后通过回调的方式实现选择后的操作。

public partial class ConfirmPopup : CommunityToolkit.Maui.Views.Popup
{
    private Action OkAction;

    private Action CancleAction;

    /// <summary>
    /// 只确认
    /// </summary>
    /// <param name="title">标题</param>
    /// <param name="content">内容</param>
    /// <param name="okAction">确认回调</param>
    /// <param name="okText">确认按钮文本</param>
    public ConfirmPopup(string title,string content,Action okAction=null,string okText="确认")
	{
		InitializeComponent();

        lbTitle.Text = title;

        lbContent.Text = content;

        btnOk.Text = okText;

        this.OkAction = okAction;

        btnCancle.IsVisible = false;
	}

    /// <summary>
    /// 可确认、取消
    /// </summary>
    /// <param name="title">标题</param>
    /// <param name="content">内容</param>
    /// <param name="okAction">确认回调</param>
    /// <param name="cancleAction">取消回调</param>
    /// <param name="okText">确认按钮文本</param>
    /// <param name="cancleText">取消按钮文本</param>
    public ConfirmPopup(string title, string content, Action okAction,Action cancleAction,string okText="确认",string cancleText="取消")
    {
        InitializeComponent();

        lbTitle.Text = title;

        lbContent.Text = content;

        btnOk.Text = okText;

        btnCancle.Text = cancleText;
         
        this.OkAction = okAction;

        this.CancleAction = cancleAction;
         
    }

    private void btnOk_Clicked(object sender, EventArgs e)
    {
        OkAction?.Invoke();

        this.Close(true);
    }

    private void btnCancle_Clicked(object sender, EventArgs e)
    {
        CancleAction?.Invoke();

        this.Close(false);
    }
}

3.使用

3.1.只需确认的弹窗

ConfirmPopup popup = new ConfirmPopup("通知","当前版本为测试版本，若出现闪退等情况请及时联系管理员进行修复！",null);

this.ShowPopup(popup);

3.2.可选择的确认弹窗

ConfirmPopup popup = new ConfirmPopup("通知", 
    "当前版本为测试版本，若出现闪退等情况请及时联系管理员进行修复！",
    async () =>
    {
      await  Toast.Make("已提交修复工单").Show();
    },
   async () =>
    {
        await Toast.Make("已取消").Show();
    });

this.ShowPopup(popup);
