Android ExpandableListView - NullPointerException?

What is holder. Stop? Holder.

Stop is NOT the view where you set the tag, so when you try to do v.getTag() you get a null in holder (incidentally, I did not see holder. Stop being initialized). Not sure exactly what you're going for, but a way to fix it would be to set the holder on the stop view as well.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
