Question

guys i have 3 groups for my expandable listview,
i try to change the color of each group respectively, when they’re expanding and back to normal color when they’re collapsing…

the problem i’ve been facing right now is that when i click the first group, it changes the color of the last group…, so i can say that they colors changed randomly not to the corresponding group.

here’s the simple code that i use:

listView.setOnGroupClickListener(new OnGroupClickListener()
    {

        @Override
        public boolean onGroupClick(ExpandableListView parent, View v, int position, long id)
        {
            v.setBackgroundResource(R.drawable.group_bar_press);

            Toast.makeText(getBaseContext(), "Group clicked", Toast.LENGTH_LONG).show();
            return false;
        }
    });

well, that’s all i hope it’ll be solved 🙂

Answer 1

i’m so sloppy :p

simply used Boolean isExpanded on my getView method, where i use to return my view,

and do it like this:

if(isExpanded){
   convertView.setBackgroundResource(R.drawable.press);
}else{
   convertView.setBackgroundResource(R.drawable.normal);
}

lol
