listview嵌套出现子listview显示不全问题解决

ListAdapter listAdapter = listView.getAdapter();
 if (listAdapter == null) return；
int totalHeight = 0;
 for (int i = 0, len = listAdapter.getCount(); i < len; i++) {
            View listItem = listAdapter.getView(i, null, listView);
            listItem.measure(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
            totalHeight += listItem.getMeasuredHeight();
        }
        ViewGroup.LayoutParams params = listView.getLayoutParams();
        params.height = totalHeight+ (listView.getDividerHeight() * (listAdapter.getCount() - 1));
        listView.setLayoutParams(params);
