How to keep the ExpandableListView Opened?

Question

I am working on the ExpandableListView I have completed the work, now only one thing that I want to do is I don\'t want the ListView to be DropDown on click of the Expandable Li

Answer 1

Open ExpandableListView Group:

 listView.expandGroup(itemPosition);

Collapse ExpandableListView Group:

 listView.collapseGroup(itemPosition);

Answer 2

Do this for every one of the groups to expand them:

listView1.expandGroup(int groupPosition);

If you want to prevent group collapse, then do this:

listView1.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener()
{
    public boolean onGroupClick(ExpandableListView arg0, View itemView, int itemPosition, long itemId)
    {
        listView1.expandGroup(itemPosition);
        return true;
    }
});

Answer 3

Solution:- To Keep The Expandable list in Expanded mode all the times It is actually very simple you dont need to do anything but just put this one line in your getGroupView of your adapter and your expandablelistview always be in opened/expanded state:--

@Override
    public View getGroupView(int groupPosition, boolean isExpanded,
            View convertView, ViewGroup parent) {

        View v = convertView;
        your_expandableListview.expandGroup(groupPosition);
        return v;
    }

This works for sure... Enjoy..!
