我有一个自定义列表视图，其中每个列表项有5个条目，这些条目来自SQLite 数据库。此列表视图中有8个列表项。我的自定义适配器代码是：
public class VaccinListAdapter extends BaseAdapter
{
private Context context;
private List<VaccinInfoPOJO> vaccinInfo;
public VaccinListAdapter(Context c,List<VaccinInfoPOJO> list)
{
context=c;
vaccinInfo=list;
}
@Override
public int getCount() {
return vaccinInfo.size();
}
@Override
public Object getItem(int pos) {
return vaccinInfo.get(pos);
}
@Override
public long getItemId(int i) {
return i;
}
@Override
public View getView(int position, View convertView, ViewGroup viewGroup) {
ViewHolder holder;
VaccinInfoPOJO entry=vaccinInfo.get(position);
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.vaccin_list_style, null);
holder=new ViewHolder();
holder.diseasevalue=(TextView)convertView.findViewById(R.id.vaccin_lv_disease);
holder.animals=(TextView)convertView.findViewById(R.id.vaccin_lv_animalnames);
holder.vaccinname= (TextView)convertView.findViewById(R.id.vaccin_lv_vaccinname);
holder.dosevalue=(TextView)convertView.findViewById(R.id.vaccin_lv_dosagevalue);
holder.timevalue= (TextView)convertView.findViewById(R.id.vaccin_lv_timevalue);
convertView.setTag(holder);
}
else {
holder = (ViewHolder) convertView.getTag();
}
holder.diseasevalue.setText(entry.getDisease());
holder.animals.setText(entry.getAnimal());
holder.vaccinname.setText(entry.getVaccine());
holder.dosevalue.setText(entry.getDose());
holder.timevalue.setText(entry.getTime());
return convertView;
}
}
我正在使用此ViewHolder类建议here：
static class ViewHolder
{
TextView diseasevalue,animals,vaccinname,dosevalue,timevalue;
}

现在去哪儿了？任何帮助都会很明显。
修改::
我犯了一个很大的愚蠢错误。当我运行循环以使用数据填充Arraylist时，循环就像：
for(cursor.moveToFirst();!cursor.isAfterLast();cursor.moveToFirst())
这里最后一次移动ToFirst将此循环变为无限状态。我将它改为moveToNext。哇...上帝保佑我。!!!
