ListView用SimpleAdapter适配器绑定

　　1、在ListView里显示数据

private void show() {
		List<Person> persons=service.getScrollData(0, 20);//需要绑定的数据，getScrollData代码在下方
List<HashMap<String, Object>> data=new ArrayList<HashMap<String,Object>>(); for(Person person:persons){ HashMap<String, Object> item=new HashMap<String, Object>(); item.put("name", person.getName()); item.put("id", person.getId()); item.put("phone", person.getPhone()); item.put("amount", person.getAmount()); data.add(item); } SimpleAdapter adapter=new SimpleAdapter(getApplicationContext(), data, R.layout.item, new String[]{"name","phone","amount"}, new int[]{R.id.name,R.id.phone,R.id.amount}); listView.setAdapter(adapter); }

　　2、getScrollData代码

	/**
	 * 分页获取记录
	 * @param offset 跳过前面多少条记录
	 * @param maxResult 每页显示多少条记录
	 * @return
	 */
	public List<Person> getScrollData(int offset,int maxResult){
		SQLiteDatabase db=dbOpenHelper.getReadableDatabase();
		List<Person> persons=new ArrayList<Person>();
		Cursor cursor=db.rawQuery("select * from person order by personid asc limit?,?", 
				new String[]{String.valueOf(offset),String.valueOf(maxResult)});
		while(cursor.moveToNext()){
			int personid=cursor.getInt(cursor.getColumnIndex("personid"));
			String name=cursor.getString(cursor.getColumnIndex("name"));
			String phone=cursor.getString(cursor.getColumnIndex("phone"));
			int amount=cursor.getInt(cursor.getColumnIndex("amount"));
			persons.add(new Person(personid, name, phone,amount));
		}
		cursor.close();
		return persons;
	}

　　3、单击一条数据事件

protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		service=new PersonService(this);
		listView=(ListView)this.findViewById(R.id.listview);
		show();
		listView.setOnItemClickListener(new ItemClickListener());//单击事件
		
	}
	
	private final class ItemClickListener implements OnItemClickListener{

		@Override
		public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
				long arg3) {
			ListView listView=(ListView)arg0;
			//SimpleAdapter适配器
			HashMap<String, Object> item=(HashMap<String, Object>)listView.getItemAtPosition(arg2);
			String name=item.get("name").toString();
			Toast.makeText(getApplicationContext(), name, 2).show();
					
		}
		
	}
