我建议每个菜单项都使用ViewModel。你可以在那里设置ImageSource可绑定属性，它可以在点击命令时更新。

public class ItemViewModel : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler? PropertyChanged;
    // You can set here your images as constants or 
    // create properties to provide image source during object initialization
    private const string DotNetBotImage = "dotnet_bot.png";
    private const string MapFillImage = "map_fill.svg";
    public ItemViewModel()
    {
        ItemTapCommand = new Command(ItemTap);
    }
    private string _itemImage = DotNetBotImage;
    public string ItemImage
    {
        get => _itemImage;
        set
        {
            _itemImage = value;
            OnPropertyChanged();
        }
    }
    private string _itemLabel = string.Empty;
    public string ItemLabel
    {
        get => _itemLabel;
        set
        {
            _itemLabel = value;
            OnPropertyChanged();
        }
    }
    public ICommand ItemTapCommand { get; private set; }
    // Update image on tap
    private void ItemTap()
    {
        if (ItemImage == DotNetBotImage)
        {
            ItemImage = MapFillImage;
        }
        else
        {
            ItemImage = DotNetBotImage;
        }
    }
    protected void OnPropertyChanged([CallerMemberName] string? propertyName = null)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

字符串
在此之后，请随意为ListView创建ObservableCollection：

public ObservableCollection<ItemViewModel> Items { get; } = new ObservableCollection<ItemViewModel>
{
    new ItemViewModel
    {
        ItemLabel = "Test1"
    },
    new ItemViewModel
    {
        ItemLabel = "Test2"
    },
    new ItemViewModel
    {
        ItemLabel = "Test3"
    }
};

下面是ListView的标记（不要忘记设置BindingContext以访问ObservableCollection）。

<ListView ItemsSource="{Binding Items}">
    <ListView.ItemTemplate>
        <DataTemplate x:DataType="vm:ItemViewModel">
            <ViewCell>
                <Grid>
                    <Grid.GestureRecognizers>
                        <TapGestureRecognizer Command="{Binding ItemTapCommand}"/>
                    </Grid.GestureRecognizers>
                    <Grid.ColumnDefinitions >
                        <ColumnDefinition Width="Auto"  />
                        <ColumnDefinition Width="*" />
                    </Grid.ColumnDefinitions>
                    <Image Grid.Column="0" Source="{Binding ItemImage}" Margin="10"/>
                    <Label Text="{Binding ItemLabel}" Grid.Column="1" HorizontalOptions="Start" HeightRequest="30"/>
                </Grid>
            </ViewCell>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>
