Android：重写SampleAdapter（示例参考）

public class SampleAdapter extends ArrayAdapter<SampleItem> {public SampleAdapter(Context context) {super(context, 0);}public View getView(int position, View convertView, ViewGroup parent) {if (convertView == null) {convertView = LayoutInflater.from(getContext()).inflate(R.layout.row, null);}ImageView icon = (ImageView) convertView.findViewById(R.id.row_icon);icon.setImageResource(getItem(position).iconRes);TextView title = (TextView) convertView.findViewById(R.id.row_title);title.setText(getItem(position).tag);return convertView;}}
