Changing recyclerView child layout at runtime.

I am trying to make some modifications to the layout of a recyclerView child at runtime. This means for example switching between two images in a child view as the user touches on it. How can i do it ? Do i have to rebind the ViewHolder? Thank you in advance

You have a Viewholder class that has a reference to the view passed into it when you create it. So extend the Viewholder class and create a setContent method in that class. There you can set an OnClick listener or whatever is needed for your view.

@Override
public void onBindViewHolder(RecyclerView.ViewHolder viewHolder, int position) {
   //cast the viewholder here to the correct viewholder type
   MyViewHolder myViewHolder = (MyViewHolder) viewHolder;
   myViewHolder.setContent();
}

public class MyViewHolder extends RecyclerView.ViewHolder {

View mView;

public MyViewHolder(View itemView) {
    super(itemView);
    mView = itemView;
}

@Override
public void setContent() {
    //set click listeners here
}
