Android 中ScrollView嵌套GridView，ListView的实例

public void setListViewHeightBasedOnChildren(ListView listView) {  
    // 获取ListView对应的Adapter  
    ListAdapter listAdapter = listView.getAdapter();  
    if (listAdapter == null) {  
      return;  
    }  

    int totalHeight = 0;  
    for (int i = 0, len = listAdapter.getCount(); i < len; i++) {  
      // listAdapter.getCount()返回数据项的数目  
      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);  
  }  

@Override
  public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    int expandSpec = MeasureSpec.makeMeasureSpec(1 << 16, MeasureSpec.AT_MOST);
    super.onMeasure(widthMeasureSpec, expandSpec);
  }
