            View listItem = listAdapter.getView(i, null, listView);   
            listItem.measure(0, 0); // 计算子项View 的宽高   
            totalHeight += listItem.getMeasuredHeight(); // 统计所有子项的总高度   
        }   
        ViewGroup.LayoutParams params = listView.getLayoutParams();   
        params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));   
        listView.setLayoutParams(params);   
    }
