Xamarin 日历选择日期

Question

我使用 Xamarin Calendar 我的项目。

https://github.com/lilcodelab/Xamarin.Plugin.Calendar

我希望当我在日历上选择一天时自动加载列表视图。不幸的是， selectedDate 没有加载。在按钮的帮助下，我选择了选定的日期并自己加载列表视图。没有按钮。你有什么建议吗？

            <controls:Calendar x:Name="xxcalendar"
                               VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">

            </controls:Calendar>
            
            <Button Margin="50,0,50,0" x:Name="xxbutton" Text="Listview_Loading" CornerRadius="10" Style="{DynamicResource ButtonStyle}" Clicked="xxbutton_Clicked"/>

            <ListView>...........</ListView>

1. 实现了点击日期显示当天的事件。

2. 已实现获取selectedDate信息。

这里是 xaml 页面：

<StackLayout>
    <controls:Calendar x:Name="ca"
        Events="{Binding Events}">
        <controls:Calendar.EventTemplate>
            <DataTemplate>
                <StackLayout
                Padding="15,0,0,0">
                    <Label
                        Text="{Binding Name}"
                        FontAttributes="Bold"
                        FontSize="Medium" />
                    <Label
                        Text="{Binding Description}"
                        FontSize="Small"
                        LineBreakMode="WordWrap" />
                </StackLayout>
            </DataTemplate>
        </controls:Calendar.EventTemplate>
    </controls:Calendar>
    <Label Text="{Binding Source={x:Reference ca},Path=SelectedDate}"></Label>
</StackLayout>

这是cs页面：

public EventCollection Events { get; set; }
public MainPage()
{
    InitializeComponent();
    Events = new EventCollection
    {
        [DateTime.Now] = new List<EventModel>
        {
            new EventModel { Name = "Cool event1", Description = "This is Cool event1's description!" },
            new EventModel { Name = "Cool event2", Description = "This is Cool event2's description!" }
        },
        [DateTime.Now.AddDays(5)] = new List<EventModel>
        {
            new EventModel { Name = "Cool event3", Description = "This is Cool event3's description!" },
            new EventModel { Name = "Cool event4", Description = "This is Cool event4's description!" }
        },
        [DateTime.Now.AddDays(-3)] = new List<EventModel>
        {
            new EventModel { Name = "Cool event5", Description = "This is Cool event5's description!" }
        },
        [new DateTime(2020, 3, 16)] = new List<EventModel>
        {
            new EventModel { Name = "Cool event6", Description = "This is Cool event6's description!" }
        }
    };
    BindingContext = this;
}
