drawable文件，xml布局文件没写

Mactivity中

MyAdapter类 中

package com.example.aa;import java.util.ArrayList;import java.util.List;import android.content.Context;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.TextView;public class MyAdapter extends BaseAdapter {    List<Person> al = new ArrayList<Person>();    Context context;    public MyAdapter(Context context) {        super();        this.context = context;    }    public void addrest(List<Person> al) {        this.al.clear();        this.al.addAll(al);        this.notifyDataSetChanged();    }    @Override    public int getCount() {        // TODO Auto-generated method stub        return al.size();    }    @Override    public Object getItem(int arg0) {        // TODO Auto-generated method stub        return null;    }    @Override    public long getItemId(int position) {        // TODO Auto-generated method stub        return 0;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        View view = View.inflate(context, R.layout.items, null);        TextView t = (TextView) view.findViewById(R.id.text);        t.setText(al.get(position).name);        return view;    }}
