First of all add make a normal view pager and in the overridden method instantiateItem

                if(position == 2) {// third page
                        View v = inflater.inflate(R.layout.expander, null, false);
                        ExpandableListView elv1 = (ExpandableListView) v.findViewById(R.id.elv1);
                        mAdapter = new BaseExpandableListAdapter() {

                    @Override
                    public Object getChild(int groupPosition,
                            int childPosition) {
                        return null;
                    }

                    @Override
                    public long getChildId(int groupPosition,
                            int childPosition) {
                        return 0;
                    }

                    @Override
                    public int getChildrenCount(int groupPosition) {
                        return 3; // Size of children usually taken from
                                    // .length or .size()
                    }

                    @Override
                    public View getChildView(int groupPosition,
                            int childPosition, boolean isLastChild,
                            View convertView, ViewGroup parent) {
                        View v = inflater.inflate(R.layout.twolinelistitem,
                                null, false);
                        TextView tv = (TextView) v
                                .findViewById(R.id.simple_expandable_list_item_2_text1);
                        tv.setText("Child " + (childPosition + 1)
                                + " of group " + (groupPosition + 1));
                        return v;
                    }

                    @Override
                    public Object getGroup(int groupPosition) {
                        return null;
                    }

                    @Override
                    public int getGroupCount() {
                        return 12; // Groups count usually taken from
                                    // .length or .size()
                    }

                    @Override
                    public long getGroupId(int groupPosition) {
                        return 0;
                    }

                    @Override
                    public View getGroupView(int groupPosition,
                            boolean isExpanded, View convertView,
                            ViewGroup parent) {
                        View v = inflater.inflate(R.layout.twolinelistitem,
                                parent, false);
                        TextView tv = (TextView) v
                                .findViewById(R.id.simple_expandable_list_item_2_text1);
                        tv.setText("Group " + (groupPosition + 1));
                        return v;
                    }

                    @Override
                    public boolean hasStableIds() {
                        return false;
                    }

                    @Override
                    public boolean isChildSelectable(int groupPosition,
                            int childPosition) {
                        return true;
                    }
                };
                elv1.setAdapter(ViewPagerPlusExpandableListActivity.this.mAdapter);

                ((ViewPager) collection).addView(v, 0);
                return v;
            }

I am sure you are lost, this is why i made this example and posted it on github
