直接上代码.

private void setListViewHeight(ListView fragLv) {

            //获得ListView的适配器
            ListAdapter adapter = fragLv.getAdapter();
            if (adapter == null) return;
            int height = 0;
            for (int i = 0; i < adapter.getCount(); i++) {
                //拿到Item
                View listViewItem = adapter.getView(i, null, fragLv);
                //计算宽高
                listViewItem.measure(0, 0);
                //叠加没一个子项的宽高
                height += listViewItem.getMeasuredHeight();
            }
            //设置高度
            ViewGroup.LayoutParams params = fragLv.getLayoutParams();
            //Item的高度乘以分割线的高度
            params.height = height + ((fragLv.getDividerHeight()) * (adapter.getCount() - 1));
            fragLv.setLayoutParams(params);
        }
