在ListView中切换不会触发

如何解决在ListView中切换不会触发

我正在列表视图中填充设置，但是我想让它保持通用状态，只是像这样设置类，但是当我切换值时，它不会触发命令 对于我的开关，我已经使用它添加了命令。 它在列表https://damienaicheh.github.io/xamarin/xamarin.forms/2019/05/17/how-to-add-command-to-a-switch-in-xamarin-forms-en.html

之外有效

public class Settings
{
    public string Type { get; set; }
    public bool Value { get; set; }
    public Command command { get; set; }
}

然后我正在加载这样的特定设置

public CustomSettingsviewmodel()
{
    LoadSetting();
   
}

private void LoadSetting()
{
    foreach (var setting in _customSettings.ScanSettings)
    {
        var detail = new Settings()
        {
            Type = setting.Type,Value = setting.Value,command = new Command<Settings>((value) => ExecutePageCommand(value))
        };
        Setting.Add(detail);
    }
}

命令

private void ExecutePageCommand(Settings settings)
{
    foreach (var result in _customSettings.ScanSettings.Where(d => d.Type == settings.Type))
    {
        var detail = new ScanSetting()
        {
            Value = settings.Value,};
    }
}

<Grid  BackgroundColor="{DynamicResource PageBackgroundColor}"  x:Name="grid" HorizontalOptions="FillAndExpand" ColumnSpacing="0">
  <!--Data-->
  <Label Grid.Row="0" Text ="{Binding Type}"   Style="{StaticResource SubLabelStyle}" HorizontalOptions="Start" Padding="10" VerticalOptions="End"   />
  <Switch Grid.Row="0"  IsToggled="{Binding Value}" HorizontalOptions="End" VerticalOptions="CenterandExpand" >
    <Switch.Behaviors>
      <control:SwitchBehavIoUr Command="{Binding  command}" />
    </Switch.Behaviors>
  </Switch>
</Grid>    

但是，我不确定如何更改确切属性上开关的值，因此它只会更改一个值。你能请教吗？
