ExpandableListView in Scrollview

expandablelistview_oncreate.java

@Override

    View view = inflater.inflate(R.layout.expandable, container, false);

    ExpandableAdapter adapter = new ExpandableAdapter();

            setExpandableListViewHeight(parent, position);
            return false;
        }
    });
    return view;

    for (int i = 0; i < listAdapter.getGroupCount(); i++) {
        View groupItem = listAdapter.getGroupView(i, false, null, listView);
        groupItem.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED);
 
        totalHeight += groupItem.getMeasuredHeight();
 
        if (((listView.isGroupExpanded(i)) && (i != group))
                || ((!listView.isGroupExpanded(i)) && (i == group))) {
            for (int j = 0; j < listAdapter.getChildrenCount(i); j++) {
                View listItem = listAdapter.getChildView(i, j, false, null,
                        listView);
                listItem.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED);
 
                totalHeight += listItem.getMeasuredHeight();
 
            }
        }
    }
 
    ViewGroup.LayoutParams params = listView.getLayoutParams();
    int height = totalHeight
            + (listView.getDividerHeight() * (listAdapter.getGroupCount() - 1));
    if (height < 10)
        height = 200;
    params.height = height;
    listView.setLayoutParams(params);
    listView.requestLayout();
 
}

Please share me the setExpandableListViewHeight(expandableListView,-1) Method codes., Thanks in Advance

This works really fine below method

Perfectly Worked.

awesome, thank you!

Why use this line setExpandableListViewHeight(expandableListView, -1); ?
Because when I use this my ExpandabeListView is showing in scroll initially but it set normal when i expanded any item

remains lots of space before click on any group,after clicking everything ok

give me solution

Excelente lo de shobishani , me funciono al 100

I would only add after children loop

totalHeight += (listView.getDividerHeight() * (listAdapter.getChildrenCount(i) - 1));

I used this method on my extendedListView but at first unnecessary extra space remains in my activity. Then I clicked a group, and it fixed. How to fix this problem?

I solved it. You can use it.
