关于RecyclerView嵌套ListView只显示一行数据解决办法

解决办法:

       通过代码，根据listview的列表项计算高度

代码如下:

private void setPullLvHeight(ListView listView){
        int totalHeight = 0;
        ListAdapter adapter= listView.getAdapter();
        for (int i = 0, len = adapter.getCount(); i < len; i++) {
            View listItem = adapter.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() * (listView.getCount() - 1));
        listView.setLayoutParams(params);
    }
