BaseAdapter可以实现自定义的丰富子项视图，本文实现如下所示结果：
实现代码：
/*
ListView :列表 BaseAdapter 通用的基础适配器 *
* */
public class BaseAdapter_test extends Activity { private ListView listview;
private int[] images=new int[]{
R.drawable.s1,
R.drawable.s2,
R.drawable.s3,
R.drawable.s4,
R.drawable.s5}; private BaseAdapter adapter;
private Context context;
private List<Map<String,Object>> datas;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.baseadapate);
context = this;
listview = (ListView) findViewById(R.id.listview); initData(); adapter=new MyAdapter(); listview.setAdapter(adapter); listview.setOnItemClickListener(new OnItemClickListener() { @Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) { Toast.makeText(context,"你选中的listview是："+ datas.get(position).get("map_content"), ).show();
}
}); }
//自定义适配器
private class MyAdapter extends BaseAdapter
{ @Override
public int getCount() {
// TODO Auto-generated method stub
return datas.size();
} @Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return datas.get(position);
} @Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
} @Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub ViewHolder viewHolder;
if(convertView==null)//重用view
{ viewHolder=new ViewHolder(); convertView=LayoutInflater.from(context).inflate(R.layout.items, null);
viewHolder.image=(ImageView) convertView.findViewById(R.id.image);
viewHolder.content=(TextView)convertView.findViewById(R.id.content);
viewHolder.button =(Button)convertView.findViewById(R.id.button);
convertView.setTag(viewHolder);
}
else
{
viewHolder=(ViewHolder) convertView.getTag();
}
//给每一个item中的控件赋值
final Map mymap=datas.get(position);
viewHolder.image.setImageBitmap((Bitmap) mymap.get("map_image"));
viewHolder.content.setText(mymap.get("map_content")+"");
viewHolder.button.setOnClickListener(new OnClickListener() { @Override
public void onClick(View v) {
Toast.makeText(context, "你选中的adapter是:"+mymap.get("map_content"), ).show(); }
}); return convertView;
} } private class ViewHolder
{
public ImageView image;
public TextView content;
public Button button; }
private void initData() { datas = new ArrayList<Map<String,Object>>();
for(int i=;i<;i++)
{
Map<String,Object> map = new HashMap<String, Object>();
map.put("map_image",BitmapFactory.decodeResource(getResources(), images[i]));
map.put("map_content", "hahacontent"+i);
datas.add(map);
}
} }
