A generic Android ViewHolder class that simplifies the standard ViewHolder pattern. Credit goes to http://www.piwai.info/android-adapter-good-practices/

ViewHolder.java

public class ViewHolder {
    @SuppressWarnings("unchecked")
    public static <T extends View> T get(View view, int id) {
        SparseArray<View> viewHolder = (SparseArray<View>) view.getTag();
        if (viewHolder == null) {
            viewHolder = new SparseArray<View>();
            view.setTag(viewHolder);
        }
        View childView = viewHolder.get(id);
        if (childView == null) {
            childView = view.findViewById(id);
            viewHolder.put(id, childView);
        }
        return (T) childView;
    }
}


// USAGE in getView() of a BaseAdapter

// if (convertView == null) {
//     convertView = LayoutInflater.from(context).inflate(R.layout.my_layout, parent, false);
// }

// ImageView bananaView = ViewHolder.get(convertView, R.id.banana);
