如何在MvxLIstView中获取所选项目

private ObservableCollection<ItemModel> selectedItems;
public ObservableCollection<ItemModel> SelectedItems
{
    get { return selectedItems; }
    set { SetProperty(ref selectedItems, value); }
}

<MvxListView
    ItemsSource="{Binding Items}"
    SelectedItem="{Binding SelectedItems, Mode=TwoWay}">
    <!-- ListView的其他设置 -->
</MvxListView>

private ObservableCollection<ItemModel> selectedItems;
public ObservableCollection<ItemModel> SelectedItems
{
    get { return selectedItems; }
    set
    {
        SetProperty(ref selectedItems, value);
        // 处理所选项目的变化
        // 例如，你可以在这里触发一个命令来执行特定的操作
    }
}
