我的主要片段是java代码

    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View root=inflater.inflate(R.layout.fragment_main_page, container, false);

this.referans_linkim("Referans Linkim","12345678","kobi45678");

Exp_Ref_List_Adapter exp_ref_list_adapter=new Exp_Ref_List_Adapter(SizeOzel.this.getActivity());

        final ExpandableListView exp_ref = (ExpandableListView)root.findViewById(R.id.exp_referans_linkim);

        DisplayMetrics metrics = new DisplayMetrics();//for determine indicator position
       SizeOzel.this.getActivity().getWindowManager().getDefaultDisplay().getMetrics(metrics);
        int width = metrics.widthPixels;

        final float scale = getResources().getDisplayMetrics().density;
    int elli=    (int) (50 * scale + 0.5f);
    int on= (int) (10 * scale + 0.5f);

        exp_ref.setIndicatorBounds(width-elli,width-on);

        exp_ref.setAdapter(exp_ref_list_adapter);

// Add on group expand listener.
        exp_ref.setOnGroupExpandListener(new ExpandableListView.OnGroupExpandListener() {
            @Override
            public void onGroupExpand(int groupIndex) {
                // Get total group size.
                int groupListSize = ref_groupList.size();

                // Close other expanded group.
                for(int i=0;i < groupListSize; i++) {
                    if(i!=groupIndex) {
                        exp_ref.collapseGroup(i);
                    }
                }
            }
        });

 // Referansım linkim data assign
    private void referans_linkim(String name,String temsil_kod,String kobi_kod)
    {
        if(this.ref_groupList == null)
        {
            this.ref_groupList = new ArrayList<String>();
        }

        if(this.ref_childListMap == null)
        {
            this.ref_childListMap = new HashMap<String, List<String>>();
        }

        if(!this.ref_groupList.contains(name)) {
            this.ref_groupList.add(name);
        }

        // Create child list.
        List<String> childList = new ArrayList<String>();
        childList.add("Temsilci Kodu:  " + temsil_kod);
        childList.add("Kobi Kodu:  " + kobi_kod);

        // Add child data list in the map, key is group name.
        this.ref_childListMap.put(name, childList);
    }

}

当我尝试扩展我的可扩展列表视图时，它会扩展。但它会压缩自己以确定宽度和高度。我想浮动可扩展列表下的项目。我该怎么办？提前致谢
