There is an example for using the onChildClick and in onCreate the line getExpandableListView().setOnChildClickListener(this); is included

That implies that in this example the class referred to by "this" implements the OnGroupClickListener interface. Does it?

 

so if I want to also have onGroup click I assumed that I need getExpandableListView().setOnGroupClickListener(this);

You need an OnGroupClickListener, where you get it from, whether it is "this" or another instance, is fairly irrelevant. 

 

but that causes an error the suggestion in Eclipse is to change it to getExpandableListView().setOnGroupClickListener((OnGroupClickListener) this);

Eclipse doesn't know any better. You should. This will get it to compile but will crash as you saw.

 

I am after any item click if there is another way, the code that I want to run onClick is the same for Group or Child. I can see in the parent class there is an event but I don't know how to use it, I am new to this.

You may need to take a step back and learn some Java first, as it appears you're getting hung up on some basic semantics of the language.
