try this,

int count = (new ExpAdapter(this)).getGroupCount();
        b.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                for (int i = 0; i < count; i++)
                {
                    expList.collapseGroup(i);
                }

            }
        });
