在RecyclerView Cell元素上具有多种单击类型-Xamarin.Android

Question

For having Click listner on a cell in RecyclerView in Xamarin.Android we have a general methode which is :

mAdapter.ItemClick += OnItemClick; // in OnCreate

and

void OnItemClick (object sender, int position)
        {
            // Display a toast that briefly shows the enumeration of the selected photo:
            int photoNum = position + 1;
            Toast.MakeText(this, "This is photo number " + photoNum, ToastLength.Short).Show();
        }

In ViewHolder we put this code :

itemView.Click += (sender, e) => listener (base.LayoutPosition);

And in RecyclerView.Adapter we have :

public event EventHandler<int> ItemClick;

with :

// Raise an event when the item-click takes place:
        void OnClick (int position)
        {
            if (ItemClick != null)
                ItemClick (this, position);
        }

Everything works well, BUT IF I want to have more than one type of click on items in ViewHolder, how can I manage this?

For example, I want to define a click on Image which open an activity. And if user click on TextView in the same ViewHolder, it does another action.

Image = itemView.FindViewById<ImageView> (Resource.Id.imageView); 
Image.Click += (sender, e) => listener (base.LayoutPosition); 
Caption = itemView.FindViewById<TextView> (Resource.Id.textView); 
Caption.Click += ???

Answer 1

You can use an interface to handle this case.

I have post my project on github .

Update:

You can use View 's setTag method to store the position.
