关于WindowManager,一直都很想写一篇博客分享一下,一直在忙别的,今天抽空把这个分享一下

在弹窗在移动开发是一个很常见的交互,很多时候我们都需要进行弹窗,比如我们需要询问用户的一些操作,提供更丰富的交互,又比如我们需要弹出一个框提示用户给我们好评

WP系统提供关于对话框的操作只有一个MessageBox,MessageBox样式简单,并且无法扩展,比如我们需要自定义按钮的文字都不可以,极大限制了我们的发挥,如果我们需要弹窗,还有Popup控件可以用,比如Coding4fun就对Popup进行了扩展,提供了更丰富对话框样式

用CM(Caluburn.Micro)也有一段时间了,CM不仅提供了MVVM的支持,还提供了IoC依赖注入容器,还提供了WindowManager的支持(这是一个非常值得深入研究的开源框架)可以在页面的ViewModel中直接通过控件对应的ViewModel构造控件进行显示,下面我们对控件进行

 

一、页面框架层次

首先说明一下页面框架的层次关系:

  Frame:最底层

  Page:页面在Frame的上层

  Popup:在页面的上层,弹出的控件会在覆盖在页面的上面

  ApplicationBar:应用程序栏不会被Popup覆盖,所以自定义的弹窗是不能把ApplicationBar给遮住的

  键盘和MessageBox:键盘在系统弹窗会把上面所有的元素都覆盖,如果ApplicationBar存在的时候,键盘会在ApplicationBar上面

 

二、WindowManager职责

  WindowManager通过封装Popup,给为外部提供很方便的弹窗操作,下面列举一下WindowManager关于弹窗所做的操作(基于CM)

    1、新建一个Host:当我们显示弹窗之前,我们需要一个容器(ContentControl)用于内部管理

    2、通过ViewModel找到对应的View(控件),并且将ViewModel绑定到View上(CM)

    3、Host.Content = view

    4、ApplySetting:通过反射设置信息,CM默认的WindowManager提供了对Host的设置

    5、判断ViewModel是否实现IActivate和IDeactivate事件,如果有,则绑定事件(在弹窗打开和关闭的时候触发)

    6、接管BackKey:比如用户按返回键是否需要关闭弹窗

    7、接管ApplicationBar:由于Popup在ApplicationBar下层,无法遮住ApplicationBar,一般的做法是隐藏掉ApplicationBar,或者是禁用掉ApplicationBar上的按钮和MenuItem,在弹窗关闭后,恢复ApplicationBar原有的状态

    8、接管Page.OrientationChanged事件:一般我们不处理该事件

    9、Popup.IsOpen = true;  打开弹窗(打开之前一般设置其Opacity为0,防止闪一下)

    10、开启弹窗动画(CM默认没有提供动画的支持,后面我们自定义的时候加入该支持)

 

定义WindowManager主要就是上面一些操作,这里不分析CM中的WindowManager的源码了,有兴趣的可以去看,但是CM提供的WindowManager还是不够用,我们需要可以更多自定义的一些配置,比如:

  1、弹窗的时候是否隐藏ApplicationBar

  2、弹窗的时候点击其他区域是否关闭弹窗

  3、弹窗是否需要用一个遮罩遮住原来页面

  4、弹窗是否支持动画注入(支持扩展)

  5、弹窗是否可以被返回键关闭

三、定义与实现

  原本是想直接继承WindowManager来做的,但是发现WindowManager提供的属性和方法太少了,很难扩展,所以下面通过自定义的方式扩展

  定义接口

 

    public interface ICustomWindowManager : IWindowManager
    {
        void ShowDialog(object rootModel, bool isTapClose = true, double maskOpacity = 0.8, IWindowAnimator windowAnimator = null, bool isHideApplicationBar = true, bool canClose = true);
    }

 

  实现:

    动画接口

    /// <summary>
    /// WindowManager动画的接口(用于扩展动画)
    /// </summary>
    public interface IWindowAnimator
    {
        void Enter(FrameworkElement viewContainer, FrameworkElement host);
        void Exit(FrameworkElement viewContainer, FrameworkElement host, Action complete);
    }

    WindowAnimator动画默认实现

    /// <summary>
    /// 默认弹窗动画的实现(渐入和渐出)
    /// </summary>
    public class DefaultWindowAnimator : IWindowAnimator
    {
        public void Enter(FrameworkElement viewContainer, FrameworkElement host)
        {
            var storyboard = new Storyboard();
            var doubleAnimation = new DoubleAnimation
            {
                Duration = new Duration(TimeSpan.FromSeconds(0.1)),
                From = 0,
                To = 1
            };
            Storyboard.SetTarget(doubleAnimation, host);
            Storyboard.SetTargetProperty(doubleAnimation, new PropertyPath("Opacity", new object[0]));
            storyboard.Children.Add(doubleAnimation);
            storyboard.Begin();
        }

        public void Exit(FrameworkElement viewContainer, FrameworkElement host, Action complete)
        {
            var storyboard = new Storyboard();
            var doubleAnimation = new DoubleAnimation
            {
                Duration = new Duration(TimeSpan.FromSeconds(0.1)),
                From = 1,
                To = 0
            };
            Storyboard.SetTarget(doubleAnimation, host);
            Storyboard.SetTargetProperty(doubleAnimation, new PropertyPath("Opacity", new object[0]));
            storyboard.Children.Add(doubleAnimation);
            storyboard.Completed += (sender, e) => complete.Invoke();
            storyboard.Begin();
        }
    }

                From = 90,
                To = 0

            };
            Storyboard.SetTarget(doubleAnimation, host);
            Storyboard.SetTargetProperty(doubleAnimation, new PropertyPath("Opacity", new object[0]));
            storyboard.Children.Add(doubleAnimation);
            storyboard.Begin();
        }

        {

            var doubleAnimation = new DoubleAnimation
            {
                Duration = new Duration(TimeSpan.FromSeconds(DURATION_SECONDS)),
                From = 0,
                To = 90
            };

            Storyboard.SetTarget(doubleAnimation, viewContainer.Projection);
            Storyboard.SetTargetProperty(doubleAnimation, new PropertyPath("RotationX", new object[0]));
            storyboard.Children.Add(doubleAnimation);

            doubleAnimation = new DoubleAnimation
            {
                Duration = new Duration(TimeSpan.FromSeconds(DURATION_SECONDS)),
                From = 1,
                To = 0
            };
            Storyboard.SetTarget(doubleAnimation, host);
            Storyboard.SetTargetProperty(doubleAnimation, new PropertyPath("Opacity", new object[0]));
            storyboard.Children.Add(doubleAnimation);


            storyboard.Completed += (sender, e) => complete.Invoke();
            storyboard.Begin();
        }

                maskingLayer.Dispatcher.BeginInvoke(() => animator.Enter(Content, host));
            }

            Uri currentPageUri;
            void OnNavigating(object sender, System.Windows.Navigation.NavigatingCancelEventArgs e)

                if (IsSystemDialogNavigation(e.Uri))

        {
        }
    }
CustomWindowManager

 

四、使用

 

  使用很简单,首先我们定义一个自定义窗口

bubuko.com,布布扣
<UserControl x:Class="XTuOne.Friday.Controls.Views.CommonDialogView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             VerticalAlignment="Top"
             FontFamily="{StaticResource PhoneFontFamilyNormal}"
             FontSize="{StaticResource PhoneFontSizeNormal}"
             Foreground="{StaticResource PhoneForegroundBrush}"
             d:DesignHeight="480"
             d:DesignWidth="480"
             mc:Ignorable="d">

    <Grid Background="#1F1F1F">
        <StackPanel Margin="12 48 12 12">
            <TextBlock x:Name="Title"
                       Margin="{StaticResource PhoneHorizontalMargin}"
                       FontFamily="{StaticResource PhoneFontFamilySemiBold}"
                       FontSize="{StaticResource PhoneFontSizeLarge}"
                       Foreground="White"
                       TextWrapping="Wrap" />
            <TextBlock x:Name="Text"
                       Margin="12 24"
                       Foreground="White"
                       Style="{StaticResource PhoneTextTitle3Style}"
                       TextWrapping="Wrap" />
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition />
                    <ColumnDefinition />
                </Grid.ColumnDefinitions>
                <Button x:Name="Ok"
                        Grid.Column="0"
                        BorderBrush="White"
                        Foreground="White">
                    <TextBlock x:Name="OkText" Text="Ok" />
                </Button>
                <Button x:Name="Cancel"
                        Grid.Column="1"
                        BorderBrush="White"
                        Foreground="White">
                    <TextBlock x:Name="CancelText" Text="Cancel" />
                </Button>
            </Grid>
        </StackPanel>
    </Grid>
</UserControl>
自定义弹窗控件:CommonDialogView

  后台没有内容,就不贴,然后定义控件对应的ViewModel

bubuko.com,布布扣
    public enum DialogResult
    {
        Cancel,
        Ok,
        Close,
    }

    public class CommonDialogViewModel : Screen
    {
        //返回值
        public DialogResult Result { get; private set; }

        //对话框的标题
        public string Title { get; set; }

        //对话框的文字
        public string Text { get; set; }

        //左边按钮的文字
        public string OkText { get; set; }

        //右边按钮的文字
        public string CancelText { get; set; }


        public CommonDialogViewModel()
        {
            Result = DialogResult.Close;
            OkText = "Ok";
            CancelText = "Cancel";
        }

        public void Ok()
        {
            Result = DialogResult.Ok;
            TryClose();
        }

        public void Cancel()
        {
            Result = DialogResult.Cancel;
            TryClose();
        }
    }
CommonDialogViewModel

  接下来是使用

    var windowAnimator = new FlipWindowAnimator();
    var customWindowManager = new CustomWindowManager();

    var commonDialog = new CommonDialogViewModel
    {
        Title = "提示",
        Text = "该手机号已经注册过,您可以:",
        CancelText = "换个手机",
        OkText = "直接登录"
    };

    commonDialog.Deactivated += (s, e) =>
    {
        if (commonDialog.Result == DialogResult.Ok)
        {
            //用户点击左边按钮
           
        }
        else if (commonDialog.Result == DialogResult.Cancel)
        {
            //用户点击右边按钮
        }
        else
        {
            //非用户点击按钮关闭(用户点击返回键或离开App)
        }
    };
    customWindowManager.ShowDialog(commonDialog, false, 0.8, flipWindowAnimator, false);

  效果图

注意:  

  为了防止多个弹窗导致HideApplicationBar冲突问题
  由于这里是通过ApplicationBar.IsMenuEnable来判断是否被禁用的
  所以请保证ApplicationBar.IsMenuEnable为true
