Xamarin表单MasterDetailPage MasterBounds

Question

can someone tell me how to edit the value for MasterBounds in XF-MasterDetailPage. My changes have no effect (MasterDetailPageRenderer/Android):

protected override void OnLayout(bool changed, int l, int t, int r, int b)
{
  base.OnLayout(changed, l, t, r, b);
  if (page != null && page.MasterBehavior == MasterBehavior.Split)
  {
    if (((IMasterDetailPageController)page).MasterBounds.Y > 0)
    {
      Rectangle rect = ((IMasterDetailPageController)page).MasterBounds;
      rect.Y = 0;
      ((IMasterDetailPageController)page).MasterBounds = rect;
    }
  }
}

I need to do this, because the value for Y is wrong on some Devices, so there is a bit of space at the top.

Thanks!

In case someone else needs this, here is the solution:

public override void AddView(Android.Views.View child)
{
  child.GetType()?.GetProperty("TopPadding")?.SetValue(child, 0);
  base.AddView(child);
}
