In my BaseExpandableListAdaptar i have List of class AdaptorData. This AdaptorData consists of Date and Object of Payment class. I am getting Payment object for every date in my adaptor. i.e. 25 mar - payment 1 25 mar - payment 2,26 mar payment 3, 26 mar payment 4,26 mar payment 5 etc. In my get group view method i have added logic like if payment data coming from same date then it should come under only that date. All works perfectly, Only when i scroll up my data gets scattered, That is 26 mar records will go under 25 march.
Here is my code-
Adapter-
public class PaymentAdapter extends BaseExpandableListAdapter implemen Filterable {
private LayoutInflater inflater;
private BaseActivity context;
private List<AdaptorData> dataAdaptor;
public String currentDate;
private List<AdaptorData> mStringFilterList;
ValueFilter valueFilter;
private String dateObj;
private ValueFilter mFilter = new ValueFilter();
public PaymentAdapter(final BaseActivity context, final List<AdaptorData> dataAdaptor) {
this.context = context;
this.dataAdaptor = dataAdaptor;
this.mStringFilterList = dataAdaptor;
inflater = LayoutInflater.from(context);
}

public int getGroupCount() {
return dataAdaptor.size();
}

I have tried all ways mentioned [here] (Android - Expandable ListView - using ViewHolder for optimization)! and [here] How ListView's recycling mechanism works)!
Also, I have tried setTag for view and get tag for that view. that code is commented in code. But nothing is working for me.
Can any one help me on this? Please let me know if you want more info.
