按照hashmap中的key为name字段排序：

private void descSort(final String order,String dir){ 
            Collections.sort(arrayList, new Comparator<HashMap<String,Object>>(){ 
                @Override 
                public int compare(HashMap<String, Object> arg0,HashMap<String, Object> arg1) { 
                    return ((String) arg1.get("name")).compareTo((String) arg0.get("name")); 
                } 
            }); 
    }
