Android实现listview tag,重写adapter

public class SoftListAdapter extends BaseAdapter {private Context context;private ArrayList<Map<String, Object>> list;public SoftListAdapter(Context con, ArrayList<Map<String, Object>> lis) {this.context = con;this.list = lis;}// 决定 getView循环几次@Overridepublic int getCount() {return list.size();}@Overridepublic Object getItem(int arg0) {return arg0;}@Overridepublic long getItemId(int position) {return position;}// 自定义适配方法@Overridepublic View getView(int position, View convertView, ViewGroup parent) {if (list.get(position).get("tag") != null&& (Boolean) list.get(position).get("tag")) {// 如果是标签项convertView = LayoutInflater.from(context.getApplicationContext()).inflate(R.layout.permission_soft_vlist_tag, null);} else {// 否则就是数据项convertView = LayoutInflater.from(context.getApplicationContext()).inflate(R.layout.permission_soft_vlist, null);ImageView img = (ImageView) convertView.findViewById(R.id.img);img.setImageDrawable((Drawable) list.get(position).get("img"));}TextView text = (TextView) convertView.findViewById(R.id.text);text.setText(list.get(position).get("text").toString());return convertView;}}

ArrayList<Map<String, Object>> data = new ArrayList<Map<String, Object>>();map.put("text", tagString);map.put("tag", true);data.add(map);
