如何獲取ListView中的Picker選定項？

Question

我正在做一個listview，我有一個標籤和Picker.I想要檢測列表視圖中選擇器的選定項目。我無法訪問xaml中選擇器的x：名稱。 cs file.Below是我的代碼。如果我的方向錯誤，任何人都可以幫助我。感謝您的提前。

這裏是我的XAML代碼：

    <ListView x:Name="MasterRoomList" BackgroundColor="Transparent" 
             ItemsSource="{Binding MasterRoomWindowsList}" 
             IsVisible="{Binding RoomsVisibility}" ItemTapped="OnItemTapped" SeparatorVisibility="None"> 
        <ListView.HeightRequest> 
        <OnIdiom x:TypeArguments="x:Double"> 
         <OnIdiom.Phone> 
         <OnPlatform x:TypeArguments="x:Double" iOS="150" Android="150" WinPhone="150" /> 
         </OnIdiom.Phone> 
         <OnIdiom.Tablet> 
         <OnPlatform x:TypeArguments="x:Double" iOS="300" Android="300" WinPhone="300" /> 
         </OnIdiom.Tablet> 
        </OnIdiom> 
        </ListView.HeightRequest> 
        <ListView.ItemTemplate> 
        <DataTemplate> 
         <ViewCell> 
         <Grid Padding="2"> 
          <Grid.ColumnDefinitions> 
          <ColumnDefinition Width="*"/> 
          <ColumnDefinition Width="*"/> 
          </Grid.ColumnDefinitions> 
          <Label Grid.Column="0" Text="{Binding RoomName}" TextColor="Black" FontFamily="Avenir Book" VerticalTextAlignment="Center"> 
          <Label.FontSize> 
           <OnIdiom x:TypeArguments="x:Double"> 
           <OnIdiom.Phone> 
            <OnPlatform x:TypeArguments="x:Double" iOS="13" Android="13" WinPhone="13" /> 
           </OnIdiom.Phone> 
           <OnIdiom.Tablet> 
            <OnPlatform x:TypeArguments="x:Double" iOS="20" Android="20" WinPhone="20" /> 
           </OnIdiom.Tablet> 
           </OnIdiom> 
          </Label.FontSize> 
          </Label> 
          <Picker x:Name="CurtainPicker" BackgroundColor="Transparent" TextColor="Black" ItemsSource="{Binding CurtainsTypeList}" SelectedIndexChanged="CurtainPicker_OnSelectedIndexChanged" Title="Select Style" Grid.Column="1" HorizontalOptions="FillAndExpand" VerticalOptions="CenterAndExpand"> 
          <Picker.HeightRequest> 
           <OnIdiom x:TypeArguments="x:Double"> 
           <OnIdiom.Tablet> 
            <OnPlatform x:TypeArguments="x:Double" iOS="40" Android="40"/> 
           </OnIdiom.Tablet> 
           <OnIdiom.Phone> 
            <OnPlatform x:TypeArguments="x:Double" iOS="30" Android="30"/> 
           </OnIdiom.Phone> 
           </OnIdiom> 
          </Picker.HeightRequest> 
          </Picker> 
         </Grid> 
         </ViewCell> 
        </DataTemplate> 
        </ListView.ItemTemplate> 
       </ListView> 

這是我Xaml.cs代碼：

private void CurtainPicker_OnSelectedIndexChanged(object sender, EventArgs e) 
    { 
     var selectedItem = (string) CurtainPicker.SelectedItem; 


    } 

Answer 1

var picker = (Picker)sender; 
var selectedItem = (string) picker.SelectedItem;
