如何在懒人适配器的帮助下刷新列表到android ...的基础适配器?

我正在使用http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/导航dwarwer我的图片未在列表中正确下载,以及如何在自定义列表视图中点击图片。?

   public class NavDrawerListAdapter extends BaseAdapter {

    private Context context;
    private ArrayList<NavDrawerItem> navDrawerItems;

    public NavDrawerListAdapter(Context context, ArrayList<NavDrawerItem> navDrawerItems){
        this.context = context;
        this.navDrawerItems = navDrawerItems;
    }

    @Override
    public int getCount() {
        return navDrawerItems.size();
    }

    @Override
    public Object getItem(int position) {       
        return navDrawerItems.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            LayoutInflater mInflater = (LayoutInflater)
                    context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
            convertView = mInflater.inflate(R.layout.drawer_list_item, null);
        }

        ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
        TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
        TextView txtCount = (TextView) convertView.findViewById(R.id.counter);

        imgIcon.setImageResource(navDrawerItems.get(position).getIcon());        
        txtTitle.setText(navDrawerItems.get(position).getTitle());

        // displaying count
        // check whether it set visible or not
        if(navDrawerItems.get(position).getCounterVisibility()){
            txtCount.setText(navDrawerItems.get(position).getCount());
        }else{
            // hide the counter view
            txtCount.setVisibility(View.GONE);
        }

        return convertView;
    }

}

提前谢谢
