自定义listview的显示（重写Adapter）
public class ListViewTest extends ListActivity {
/** Called when the activity is first created. */
private List<Map<String,Object>> mData;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mData = getData();
MyAdapter adapter = new MyAdapter(this);
setListAdapter(adapter);
}
private List<Map<String,Object>> getData()
{
List<Map<String,Object>> list = new ArrayList<Map<String,Object>>();
Map<String,Object> map = new HashMap<String,Object>();
map.put("name", "chen");
map.put("phone", "1376588****");
map.put("img",R.drawable.icon);
list.add(map);
return list;
}
public class ViewHolder
{
public ImageView img;
public TextView name;
public TextView phone;
public CheckBox check;
}
//重写Adapter,自己给Adapter加View，可以自定义listview每行显示的内容，如加Chekcbox，button等。Listview的多选框不好用，用这个能解决问题。
