Recycling views in custom array adapter: how exactly is it handled?

Question

I am having an unclear issue concerning the recycling of views in a getView method of a custom array adapter.

I understand that elements are reused, but how do I kn

Answer 1

You want to create a ViewHolder class in your MainActivity. Something like

 static class ViewHolder
    {
        TextView tv1;
        TextView tv2;
    }

then in your getView, the first time you get your Views from your xml in the if and reuse them after that in the else

View rowView = convertView;
        if (rowView == null)
        {
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            rowView = inflater.inflate(R.layout.layout_name_to_inflate, parent, false);
            holder = new ViewHolder();
            holder.tv1= (TextView) rowView.findViewById(R.id.textView1);
            holder.tv2 = (RadioGroup) rowView.findViewById(R.id.textView2);             
            rowView.setTag(holder);
        }
        else
        {
            holder = (ViewHolder) rowView.getTag();
        }
