继承自上面两篇的文章。本篇主要介绍分页查询和查询的总记录数：

方法为：

/**
	 * 
	 * 
	 * @param pageSize
	 *            每一页数据的大小 比如20个数据
	 * @param pageNum
	 *            多少页 比如 第一页 第二页
	 * @return
	 */

	public List<Account> queryPage(int pageSize,int pageNum) {

		String index = (pageNum - 1) * pageSize + ""; // 索引 翻页时的起始索引
		String count = pageSize + ""; // 查询多少条数据

		List<Account> list = new ArrayList<Account>();

		sqliteDatabase db = helper.getReadableDatabase();

		Cursor c = db.rawQuery("SELECT * FROM account LIMIT ?,?",new String[] {
				index,count });// 查询表中所有的数据

		while (c.moveToNext()) {

			int id = c.getInt(c.getColumnIndex("_id"));

			String name = c.getString(c.getColumnIndex("name"));

			int balance = c.getInt(c.getColumnIndex("balance"));

			list.add(new Account(id,name,balance));

		}
		c.close();
		db.close();

		return list;
	}

	/**
	 * 
	 * 查询总共有多少条数据
	 * 
	 * @return
	 */

	public int queryCount() {

		sqliteDatabase db = helper.getReadableDatabase();

		Cursor c = db.rawQuery("SELECT COUNT(*) FROM account",null);

		c.moveToNext();

		int count = c.getInt(0);

		c.close();

		db.close();

		return count;

	}

	public void testQueryPage(){
		AccountDao dao = new AccountDao(getContext());
		List<Account> list = dao.queryPage(20,1);
		for (Account account : list) {
			System.out.println(account);
		}
	}
	
	
	public void testQueryCount(){
		AccountDao dao = new AccountDao(getContext());
		
		System.out.println(dao.queryCount());
		
		
	}
