ScrollView嵌套ListView及ListView嵌套的高度计算方法

public void setListViewHeightBasedOnChildren(ListView listView) {  // 获取ListView对应的Adapter  ListAdapter listAdapter = listView.getAdapter();  if (listAdapter == null) {   return;  }  int totalHeight = 0;  // listAdapter.getCount()返回数据项的数目  for (int i = 0; i < listAdapter.getCount(); i++) {   View listItem = listAdapter.getView(i, null, listView);   // 计算子项View 的宽高   listItem.measure(0, 0);   // 统计所有子项的总高度   totalHeight += listItem.getMeasuredHeight();  }  ViewGroup.LayoutParams params = listView.getLayoutParams();  params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));  // listView.getDividerHeight()获取子项间分隔符占用的高度  // params.height最后得到整个ListView完整显示需要的高度  listView.setLayoutParams(params); }
