ScrollView 下 ListView显示不全的问题

有的时候，ScrollView下ListView列表显示不完整，可以用下面的code解决。

1 publicstaticvoid setListViewHeightBasedOnChildren(ListView listView)
2 {
3 ListAdapter listAdapter = listView.getAdapter();
4 if (listAdapter == null)
5 {
6 return;
7 }
8 int totalHeight = 0;
9 for (int i = 0, len = listAdapter.getCount(); i < len; 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.getPaddingTop() + listView.getPaddingBottom();
listView.setLayoutParams(params);
}
