Answer 1

你可以降低ListView的Padding和GridViewHeaderRowPresenter的Margin：

<ListView ... Loaded="lv_Loaded"> 

---

private void lv_Loaded(object sender, RoutedEventArgs e) 
{ 
    ListView lv = sender as ListView; 
    lv.Padding = new Thickness(-2, -1, -2, -1); 
    GridViewHeaderRowPresenter presenter = FindChild<GridViewHeaderRowPresenter>(lv); 
    if (presenter != null) 
     presenter.Margin = new Thickness(1, 0, 2, 0); 
} 

private static T FindChild<T>(DependencyObject dependencyObject) where T : DependencyObject 
{ 
    if (dependencyObject == null) return null; 

    for (int i = 0; i < VisualTreeHelper.GetChildrenCount(dependencyObject); i++) 
    { 
     var child = VisualTreeHelper.GetChild(dependencyObject, i); 

     var result = (child as T) ?? FindChild<T>(child); 
     if (result != null) return result; 
    } 
    return null; 
}
