Single selection in RecyclerView

Question

I know there are no default selection methods in recyclerview class, But I have tried in following way,

public void onBindViewHolder(ViewHolder holder, final

The solution for the issue:

public class yourRecyclerViewAdapter extends RecyclerView.Adapter {

private static CheckBox lastChecked = null;
private static int lastCheckedPos = 0;


public void onBindViewHolder(ViewHolder holder, final int position) {

    holder.mTextView.setText(fonts.get(position).getName());
    holder.checkBox.setChecked(fonts.get(position).isSelected());
    holder.checkBox.setTag(new Integer(position));

    //for default check in first item
    if(position == 0 && fonts.get(0).isSelected() && holder.checkBox.isChecked())
    {
       lastChecked = holder.checkBox;
       lastCheckedPos = 0;
    }

    holder.checkBox.setOnClickListener(new View.OnClickListener() 
    {
        @Override
        public void onClick(View v) 
        {
           CheckBox cb = (CheckBox)v;
           int clickedPos = ((Integer)cb.getTag()).intValue(); 

           if(cb.isChecked())
           {
              if(lastChecked != null)
              {
                  lastChecked.setChecked(false);
                  fonts.get(lastCheckedPos).setSelected(false);
              }                       

              lastChecked = cb;
              lastCheckedPos = clickedPos;
          }
          else
             lastChecked = null;

          fonts.get(clickedPos).setSelected(cb.isChecked);
       }
   });
}
}

Hope this help!
