I have a custom listview where each list item has 5 entries and these entries come from SQLite database. There are such 8 list-items in this listview. My code for custom adapter is:
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;
}
}
And I am using this ViewHolder class as suggested here:
static class ViewHolder
{
TextView diseasevalue,animals,vaccinname,dosevalue,timevalue;
}
I am getting Out of memory exception after a long stream of this grow heap sequence::

Where to go now? Any help would be appreciable.
EDIT::
I had made a huge silly mistake. When I was running a loop to fill the Arraylist with data the loop was like:
for(cursor.moveToFirst();!cursor.isAfterLast();cursor.moveToFirst())
here the last moveToFirst was getting this loop into infinite state. I changed it to moveToNext. Whoa...God bless me.!!!
