scrollview listview共存

         因为项目中需要使用scrollView和listview共存，这个也挺常用的。下面我就直接粘贴相应代码：

//计算listview的大小

public static void setListViewHeightBasedOnChildren(ListView listView) {
  ListAdapter listAdapter = listView.getAdapter();
  if (listAdapter == null) {
   // pre-condition
   return;
  }
  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));
  listView.setLayoutParams(params);
 }
