    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);
                    }
    
                }
            });
