ScrollView嵌套ListView只显示一行的问题

设置完ListView的Adapter后，根据ListView的子项目重新计算ListView的高度，然后把高度再作为LayoutParams设置给ListView，这样它的高度就正确了，以下是源码：
 public  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); 

    } 

 调用:

  XXAdapter adapter = new XXAdapter(getApplicationContext());
  listView.setAdapter(adapter);

 setListViewHeightBasedOnChildren(listView);
