public static void setListViewHeightBasedOnChildren(ListView listView) {

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));

Adapter中 getView () 方法返回的 View 的必須由 LinearLayout 組成燃辖。
需要手動把 ScrollView 滾動至最頂端师崎，因為使用這個方法的話瓜浸，默認在ScrollView頂端的項是ListView拂酣。
