如何正确设置此按钮与父ListView ItemsControl的绑定？

<ListView ItemsSource="{Binding MyItems}">
    <ListView.ItemTemplate>
        <DataTemplate>
            <!-- 在这里放置你的数据项模板 -->
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

<DataTemplate>
    <StackPanel>
        <!-- 其他数据项控件 -->
        <Button Content="点击按钮" Command="{Binding DataContext.MyCommand, RelativeSource={RelativeSource AncestorType={x:Type ListView}}}" CommandParameter="{Binding}" />
    </StackPanel>
</DataTemplate>

public ICommand MyCommand { get; private set; }

public MyViewModel()
{
    MyCommand = new RelayCommand(ExecuteMyCommand);
}

private void ExecuteMyCommand(object parameter)
{
    // 处理按钮点击事件的逻辑
}
