Thanks for the support!
I'm sorry for not making it clear for you... maybe I wasn't even able
to understand what I was trying to do hehe...
So, you got it right! that's exactly what I need! "get the group
position based on the button that was pressed", but the problem is
that as I'm on my first android project I have no idea what you were
talking about... I mean, I understood but I just didn't know what to
do. The first thing is that I'm not sure how to do that with my
adapter, let me show you my whole class (don't worry it's not big) so
that you can have an idea what this is doing so far:
public class ExpList extends ExpandableListActivity {
private String TAG = "myTag";
static final String texto1[][] = { { "Group 1", "test1", },
{ "Group 2", "test2", },
{ "Group 3", "test3", },
{ "Group 4", "test4", },
{ "Group 5", "test5", }, };
static final String childTexts[][] = {
{ "Rua José pinto brandão 95, apt 32B", "São Paulo - SP
- Brazil",
"55 11 56607209", },
{ "Rua José pinto brandão 95, apt 32B", "São Paulo - SP
- Brazil",
"55 11 56607209", },
{ "Rua José pinto brandão 95, apt 32B", "São Paulo - SP
- Brazil",
"55 11 56607209", },
{ "Rua José pinto brandão 95, apt 32B", "São Paulo - SP
- Brazil",
"55 11 56607209", },
{ "Rua José pinto brandão 95, apt 32B", "São Paulo - SP
- Brazil",
"55 11 56607209", } };

return false;

So where exactly should I get the parent of the button and how would I
get the view's index in the adapter? I'm not sure how Tag works.. I'll
take a look at some samples in the meanwhile...
