一、SQLITE数据库字段类型
　　NULL: 表示一个NULL值
　　INTEGER: 用来存储一个整数,根据大小可以使用1,2,3,4,6,8位来存储.
　　REAL: IEEE 浮点数
　　TEXT: 按照字符串来存储
　　BLOB: 按照二进制值存储,不做任何改变.
id自增长字段：id integer primary key autoincrement
二、SQLITE的CRUD操作
insert操作

ContentValues values=new ContentValues(); values.put("name", person.getName()); database.insert("person", null, values);
update操作

ContentValues values=new ContentValues(); values.put("name", person.getName()); database.update("person", values, "personid=?", new String[]{String.valueOf(person.getPersonId())});
select操作

Cursor cursor=database.query("person", null, null, null, null, null, null, offerset+","+maxResult); while(cursor.moveToNext()){ int personIda =cursor.getInt(cursor.getColumnIndex("personid")); String name=cursor.getString(cursor.getColumnIndex("name")); Person person=new Person(personIda,name); persons.add(person); }
delete操作
database.delete("person", "personid=?", new String[]{String.valueOf(personId)});
三、数据库版本问题
为防止应用的数据库版本变更，每次发布的应用都应指定相应的数据库版本；
如果数据库结构有变动，那么针对版本的变更进行相关升级操作
四、数据库事务操作
database.beginTransaction();//开启事务
database.setTransactionSuccessful();//当操作成功的时候把事务状态改为成功状态
database.endTransaction();//提交事务会根据事务的状态来提交事务还是回滚事务
