ios - MvvmCross:如何设置MvxCollectionViewController的itemsize占据全屏尺寸？

Question

如何将 ItemSize 设置为全尺寸宽度和高度？还可以在旋转屏幕时动态更改 ItemSize？

 public class SearchResultView : MvxCollectionViewController
    {
        private bool _isInitialised;

        public SearchResultView()
            : base(new UICollectionViewFlowLayout()
            {
                ItemSize = new SizeF(UIScreen.MainScreen.Bounds.Width, UIScreen.MainScreen.Bounds.Height),
                ScrollDirection = UICollectionViewScrollDirection.Horizontal,
            })
        {

        }
    }

How to set the ItemSize as full size width and height? Also dynamic change the ItemSize based when rotated the screen?

您可以在 DidRotate 期间更改 Collection View 的布局 - 例如:

public override void DidRotate(UIInterfaceOrientation fromInterfaceOrientation)
{
    CollectionView.SetCollectionViewLayout(new UICollectionViewFlowLayout()
        {
            ItemSize = new SizeF(View.Frame.Width, View.Frame.Height),
            ScrollDirection = UICollectionViewScrollDirection.Horizontal,
        });
}

为了使此效果产生良好的视觉显示，我猜您的 Collection View 单元格(以及任何补充 View )也需要调整大小。
