In my application i used custom list view adapter. In the list view item i added another layout. because in my service one order have any number of order items. For showing the order items i added the order item layout below to custom list view item.it is working fine. but when scroll the list view the data is changed.
adapter class:
public class PreviousDataAdapter extends BaseAdapter {
ArrayList<PreviousOrderData> bpData;
private ArrayList<PreviousOrderData> arraylist;
ArrayList<OrderItemData> opData;
private ArrayList<OrderItemData> arraylist1;
private Activity activity;
private LayoutInflater inflater;
String g_orderid;
DatabaseHandler db;
SharedPreferences m_sharedPreference;
SharedPreferences.Editor m_editor;
ArrayList<String> circless = new ArrayList<String>();
public PreviousDataAdapter(Activity activity, ArrayList<PreviousOrderData> bpData,ArrayList<OrderItemData> opdata) {
// TODO Auto-generated constructor stub
this.activity = activity;
this.bpData = bpData;
this.opData=opdata;//k?
// this.opData=bpData.get()//opdata;
inflater = LayoutInflater.from(activity);
db = new DatabaseHandler(activity);
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return bpData.size();
}
@Override
public Object getItem(int location) {
// TODO Auto-generated method stub
return bpData.get(location);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
private int lastPosition = -1;
