Fastlib库是一个多功能的android第三方库。为了能让使用者尽量使用所有的功能，我写一个记帐本的demo来让大家提升对Fastlib使用能力
看之前请先预习一下
数据库功能FastDatabase基础使用
数据库适配器基于FastDatabase适配器
封装弹窗多工具
Activity封装FastActivity
这个记账本要实现
插入记录删除记录修改记录根据条件获取记录列表（当前仅时间过滤）
消费和收入记录实体类
public class Record
implements Serializable{
//主键并且自动增长
@Database(
keyPrimary =
true,autoincrement =
true)
public int id;
public double money;
public long date; //使用long类型更好使用数据库过滤
public String
title;
public String
description;
}
