我按照https://developer.xamarin.com/guides/android/user_interface/recyclerview/上的指南
在Recyclerview项目上设置了一个带有点击事件的viewholder的recyclerview一切正常。
之后，我想将此组件用于滑动功能 https://components.xamarin.com/view/androidswipelayout
如果工作正常，滑动，但点击recyclerview项目不再触发事件。有什么建议吗？itemlayout是

观看者：
public class BookCardViewHolder : RecyclerView.ViewHolder
{
public SwipeLayout SwipeLayout;
public ImageView Icon;
public ImageView Image { get; private set; }
public TextView Title { get; private set; }
public TextView Author { get; private set; }
public TextView Progress { get; private set; }
public BookCardViewHolder (View itemView, Action<int> listener)
: base (itemView)
{
SwipeLayout = itemView.FindViewById<SwipeLayout> (Resource.Id.swipe_layout);
Icon = itemView.FindViewById<ImageView> (Resource.Id.trash);
Image = itemView.FindViewById<ImageView> (Resource.Id.imageView);
Title = itemView.FindViewById<TextView> (Resource.Id.title);
Author = itemView.FindViewById<TextView> (Resource.Id.author);
Progress = itemView.FindViewById<TextView> (Resource.Id.progress);
itemView.Click += (sender, e) => listener (base.AdapterPosition);
}
}
并在父片段中设置适配器，如下所示：
mAdapter = new BookCardAdapter (Books, this.Activity);
// Register the item click handler (below) with the adapter:
mAdapter.ItemClick += OnItemClick;
mRecyclerView.SetAdapter (mAdapter);
和：
void OnItemClick (object sender, int position)
{
// ProgressDialog progress = new ProgressDialog (this.Activity);
// progress.SetMessage ("Opening Book...");
// progress.Show ();
AndroidUtils.Read (Books [position], this.Activity);
}
