package com.njupt.listview;import java.util.List;import android.os.Bundle;import android.app.Activity;import android.view.Menu;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.ListView;import android.widget.TextView;public class MainActivity extends Activity {	private ListView personLV;	private List
    
      persons;	@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.main);	    		personLV = (ListView) findViewById(R.id.personLV);				PersonDao dao = new PersonDao(this);				persons = dao.queryAll(); 		personLV.setAdapter(new MyBaseAdapter());//给ListView添加adapter，按照adapter中的方法给ListView添加条目	}	private class MyBaseAdapter extends BaseAdapter{// 定义Adapter, 把每个Person对象生成一个条目, 将所有条目装入ListView		@Override		public int getCount() {//获取条目数量			return persons.size();		}		@Override		public Object getItem(int position) {//获取指定对象			return persons.get(position);		}		@Override		public long getItemId(int position) {//获取指定对象的id			return position;		}		@Override		public View getView(int position, View convertView, ViewGroup parent) {// 返回指定位置上的条目, 条目会被自动添加到ListView中						View item = View.inflate(getApplicationContext(), R.layout.item, null);// 根据布局文件创建View(LinearLayout)						TextView idTV =  (TextView) item.findViewById(R.id.idTV);// 获取这个新生成的View中的TextView			TextView nameTV = (TextView) item.findViewById(R.id.nameTV);			TextView balanceTV = (TextView) item.findViewById(R.id.balanceTV);						Person p = persons.get(position);// 根据位置获取Person对象			idTV.setText(p.getId() + "");// 给TextView设置文本			nameTV.setText(p.getName());			balanceTV.setText(p.getBalance()+"");						return item;		}					}	@Override	public boolean onCreateOptionsMenu(Menu menu) {		// Inflate the menu; this adds items to the action bar if it is present.		getMenuInflater().inflate(R.menu.main, menu);		return true;	}}
