}

public class ObjectAdapter extends BaseAdapter { private Context context; private List<User> list; public ObjectAdapter(Context context, List<User> list) { super(); this.context = context; this.list = list; } @Override public int getCount() { // TODO Auto-generated method stub return list.size(); } @Override public Object getItem(int arg0) { // TODO Auto-generated method stub return list.get(arg0); } @Override public long getItemId(int arg0) { // TODO Auto-generated method stub return arg0; } @Override public View getView(int postion, View view, ViewGroup listView) { //创建加载xml文件的类 LayoutInflater inflater =LayoutInflater.from(context); //加载xml 文件 view=inflater.inflate(R.layout.listview, null); //为xml 文件的控件赋值 TextView name = (TextView) view.findViewById(R.id.textView1); TextView age = (TextView) view.findViewById(R.id.textView2); name.setText(list.get(postion).getName()); age.setText(""+list.get(postion).getAge()); return view; } }
