Here is the code that show that how can i add add data into hashmap and the expandable list view. as u see there is an hashmap for expandable list view and and in the adaoter i put the title from api respose but the header for listview parent is static and the data in the child re dynamic so you can see the diffrance
You've added a lot of code but I think this is the only one which is important for your question :-
expandableListTitle.add("Today's Task")
expandableListTitle.add("Tommorow's Task")
expandableListTitle.add("Upcoming Task")
expandableListDetail.put(expandableListTitle[0], todaystitle)
expandableListDetail.put(expandableListTitle[1], tommrowtask)
expandableListDetail.put(expandableListTitle[2], upcomingtask)
Log.e("task", expandableListTitle.get(0) + " = " + expandableListDetail.put(expandableListTitle.get(0), todaystitle))
Log.e("task", expandableListTitle.get(1) + " = " + expandableListDetail.put(expandableListTitle.get(1), tommrowtask))
Log.e("task", expandableListTitle.get(2) + " = " + expandableListDetail.put(expandableListTitle.get(2), upcomingtask))
expandableListAdapter = CustomExpandableListAdapter(activity, expandableListTitle, expandableListDetail)
expandableListView!!.setAdapter(expandableListAdapter)
So As much as I have understood from the image you have added in the link what you need is you need to show the number of elements present in the child in your header right.
What you can do is simply add the total number of elements present in your list like this :-
expandableListTitle.add("Today's Task (${todaystitle.count()})") //.count() gives the total number of elements present in list
It will add title as Today's Task (10) \\ here 10 would be the number of elements present in your list. Now you can simply format in any way you want
