Group click listener in android expandable list view


I have an expandable list view where the first group is empty i.e. it has no children while all others have children . Now I have to implement onChildClick for all the groups except the first one.



For the first one the requirement is that onClick the group itself some action has to be taken.



So I implemented onGroupClickListener and put the condition




if(groupPosition == 0){ //action}



but this has disabled all the groups and now I am not able to see the children for any group.



How should I do this?

Slow Android emulator

I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
