范例：

1.MainActivity代码：

public class MainActivity extends Activity{                 //   只要在设置ListView的Adapter后调用此静态方法Utility.setListViewHeightBasedOnChildren(listview);//    即可让ListView正确的显示在其父ListView的ListItem中。//    但是要注意的是，子ListView的每个Item必须是LinearLayout，不能是其他的，因为其他的Layout(如RelativeLayout)//    没有重写onMeasure()，所以会在onMeasure()时抛出异常。                     private ArrayList
     
       dataList;    private ListView listview;    private ImageView img;    @Override    protected void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);                             dataList = new ArrayList
      
       ();        for (int i = 0; i < 5; i++)        {            String str = "第" + i + "行";            dataList.add(str);        }                             img = (ImageView) findViewById(R.id.p_w_picpathView1);        listview = (ListView) findViewById(R.id.listView1);                                                  listview.setAdapter(new BaseAdapter()        {                                     @Override            public View getView(int position, View convertView, ViewGroup parent)            {                LayoutInflater inflater = getLayoutInflater();                View layout = inflater.inflate(R.layout.item, null);                TextView tv = (TextView) layout.findViewById(R.id.tv_item);                                                                          String str = dataList.get(position);                tv.setText(str);                                             return layout;            }                                     @Override            public long getItemId(int position)            {                return 0;            }                                     @Override            public Object getItem(int position)            {                return null;            }                                     @Override            public int getCount()            {                return dataList.size();            }        });                             Utility.setListViewHeightBasedOnChildren(listview);    }}
      
     

2.Utility代码

public class Utility{    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);    }}
