点击Viewpager Xamarin Android

Question

我是Xamarin Android Development的新手.我使用ViewPager创建了Image滑块.现在我想点击那个ViewPager的图像.我可以实现吗？我试过这个但没有用过:

{
  viewpage = mview.FindViewById<ViewPager> (Resource.Id.viewpager);
  viewpage.Adapter = new itemadapter (ChildFragmentManager);
  viewpage.Click += Viewpage_Click;
}
public void Viewpage_Click (object sender, EventArgs e)
{
    ViewModel.DetailViewCommand.Execute ();
}

只实现onclick listener了imageview在viewpager's适配器如果你只有图像滑块.

编辑:imageslider viewpager从Web下载图像的完整源代码.

public class ImageSliderAdapter : PagerAdapter
    {
        Context _context;
        List<string> _imageUrls;

        public ImageSliderAdapter (Context context, List<string> imageUrls)
        {
            _imageUrls = imageUrls;
            _context = context;
        }

        public override bool IsViewFromObject (Android.Views.View view, Java.Lang.Object @object)
        {
            return view == ((LinearLayout)@object);
        }

        public override int Count {
            get {
                return _imageUrls.Count;
            }
        }

        public override void DestroyItem (ViewGroup container, int position, Java.Lang.Object objectValue)
        {
        }

        public override Java.Lang.Object InstantiateItem (ViewGroup container, int position)
        {

            View view = container;
            var inflater = _context.GetSystemService (Context.LayoutInflaterService) as LayoutInflater;
            view = inflater.Inflate (Resource.Layout.image_slider_item, null);
            var child = view.FindViewById<ImageView> (Resource.Id.image_slider_item);
            child.Click += (o, e) =>
            {
                //your code here
            };

            Bitmap image = null;
            Task.Run (() => {
                URL url = new URL (_imageUrls [position]);
                image = BitmapFactory.DecodeStream (url.OpenConnection ().InputStream);
            }).ContinueWith (t => {
                (_context as MainView).RunOnUiThread (() => {
                    child.SetImageBitmap (image);
                });
            });

            container.AddView (view);
            return view;
        }
    }

在活动中:

            var imageViewer = FindViewById<ViewPager> (Resource.Id.pager);
            imageViewer.Adapter = new ImageSliderAdapter (this, imageUrls);
