android - How to set color for position '0' of ExpandableListview -
i have 4 activity classes, need implement 4 different colors 4 activities, have expandablelistadapter like:
public class expandablelistadapter extends baseexpandablelistadapter { private context _context; private list<string> _listdataheader; // header titles // child data in format of header title, child title private hashmap<string, list<string>> _listdatachild; string colors; public expandablelistadapter(context context, list<string> listdataheader, hashmap<string, list<string>> listchilddata,string color) { this._context = context; this._listdataheader = listdataheader; this._listdatachild = listchilddata; this.colors=color; } @override public object getchild(int groupposition, int childposititon) { return this._listdatachild.get(this._listdataheader.get(groupposition)) .get(childposititon); } @override public long getchildid(int groupposition, int childposition) { return childposition; } @override public view getchildview(int groupposition, final int childposition, boolean islastchild, view convertview, viewgroup parent) { final string childtext = (string) getchild(groupposition, childposition); if (convertview == null) { layoutinflater infalinflater = (layoutinflater) this._context .getsystemservice(context.layout_inflater_service); convertview = infalinflater.inflate(r.layout.list_item, null); } checkedtextview txtlistchild = (checkedtextview) convertview .findviewbyid(r.id.lbllistitem); txtlistchild.settypeface(typefaceconstant.getgibsonregular(_context)); txtlistchild.settext(childtext); return convertview; } @override public int getchildrencount(int groupposition) { if(groupposition==2){ return this._listdatachild.get(this._listdataheader.get(groupposition)) .size(); }else return 0; } @override public object getgroup(int groupposition) { return this._listdataheader.get(groupposition); } @override public int getgroupcount() { return this._listdataheader.size(); } @override public long getgroupid(int groupposition) { return groupposition; } @override public view getgroupview(int groupposition, boolean isexpanded, view convertview, viewgroup parent) { 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); } checkedtextview lbllistheader = (checkedtextview) convertview .findviewbyid(r.id.lbllistheader); lbllistheader.settypeface(typefaceconstant.getgibsonregular(_context)); lbllistheader.settext(headertitle); return convertview; } @override public boolean hasstableids() { return false; } @override public boolean ischildselectable(int groupposition, int childposition) { return true; } and activity class like:
public class officescreenactivity extends fragmentactivity implements onclicklistener { linearlayout office,roaster,food_service,hospitality; expandablelistadapter listadapter; expandablelistview explistview;

return false; } }); } this 1 of activity classes, have 4 activity classes these, please me.
you passing colors string in expandablelistadapter's constructor never used it. if want set first group item's color need set getgroupview() method of expandablelistadapter : this:
if(groupposition==0){ lbllistheader.settextcolor(<color passing in constructor>); }
