listview嵌套listview

问题：

listview嵌套listview，会显示不全。

解决办法：

  /**         * 设置Listview的高度         */        public void setListViewHeight(ListView listView) {            ListAdapter listAdapter = listView.getAdapter();            if (listAdapter == null) {                return;            }            int totalHeight = 0;            for (int i = 0; i < listAdapter.getCount(); i++) {                View listItem = listAdapter.getView(i, null, listView);                listItem.measure(0, 0);                totalHeight += listItem.getMeasuredHeight();            }            ViewGroup.LayoutParams params = listView.getLayoutParams();            params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));            listView.setLayoutParams(params);        }
