m MODE 数据模型 List<Person>
v view 视图 ListView
c controller 控制器 adapter适配器

用listview实现63楼效果
在布局文件中加入
<ListView
android:id="@+id/lv"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
</ListView>
onCreat方法中lv.setAdapter(new MyAdapter());
创建一个内部类
private class MyAdapter extends BaseAdapter{
private static final String TAG = "MyAdapter";
/**
* 控制listview里有多少条数据
*/
@Override
public int getCount() {
return persons.size();
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView tv = new TextView(getApplicationContext());
Person person = persons.get(position);
tv.setText(person.toString());
return tv;
}
}

public View getView(int position, View convertView, ViewGroup parent) {
Person person = persons.get(position);
View view = View.inflate(MainActivity.this, R.layout.list_item, null);
//一定要在view对象中找孩子的id
TextView tv_id = (TextView)view.findViewById(R.id.tv_id);
tv_id.setText("id:" + person.getId());
填充布局文件
