I want to get the mouse coordinates where ListViewItem clicks. How can I get

<ListView ItemClick="ListItemClick" IsItemClickEnabled="True">
     <ListViewItem>
          <TextBlock Text="data" />
     </ListViewItem>
</ListView>

private void ListItemClick(object sender, ItemClickEventArgs e)
{
    MenuFlyout menu = new MenuFlyout();
    MenuFlyoutItem item1 = new MenuFlyoutItem { Text = "hello world" };
    menu.Items.Add(item1);

    int click_X = 0; // ?
    int click_Y = 0; // ?
    menu.ShowAt(sender as UIElement, new Point(click_X, click_Y));
}
