解决scrollview中嵌套listView，内容只显示一行的方法

for (int index = 0, len = listAdapter.getCount(); i < len; i++) {     
            View listViewItem = listAdapter.getView(index , null, listView); 

            listViewItem.measure(0, 0);   

            totalHeight += listViewItem.getMeasuredHeight();    

        }  

        ViewGroup.LayoutParams params = listView.getLayoutParams();  

        params.height = totalHeight+ (listView.getDividerHeight() * (listAdapter.getCount() - 1));   

        listView.setLayoutParams(params);   

    }  

获得子view 的高度与数量，计算listview所需高度，然后直接给定listview高度
