Write this code in Expandable Base adapter.

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

    String headerTitle = (String) getGroup(groupPosition);
    if (convertView == null) {
        LayoutInflater infalInflater = (LayoutInflater) this._context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = infalInflater.inflate(R.layout.list_group, null);
    }

    TextView lblListHeader = (TextView) convertView
            .findViewById(R.id.lblListHeader);
     imgs = (ImageView) convertView
            .findViewById(R.id.img_list);
    lblListHeader.setTypeface(null, Typeface.BOLD);
    lblListHeader.setText(headerTitle);
    if (isExpanded) {
  imgs.setImageResource(R.drawable.up_arrow);
    }
    else {
        imgs.setImageResource(R.drawable.downs_arrow);
    }

    return convertView;
}
