单机android   sqlite数据库的实现,这个数据库可与程序一起生成在安装包中

一、下载sqlite3.exe文件

二、运行 cmd 转到sqlite3.exe 所在目录  运行 sqlite3.exe 数据库名.db

    然后会出现sqlite>的命令提示符

    输入创建表的语句, create table 表名(‘列’,‘列’。。。);(注意: 要在结束部分加  分号 )

    此时会在sqlite3.exe 所在目录,出现所建数据库的文件

三、如果想在Android中运行的话,需要在数据库中增添

 CREATE TABLE "android_metadata" ("locale" TEXT DEFAULT 'zh_CN')
INSERT INTO "android_metadata" VALUES ('zh_CN')

四、将数据库 复制到 Android项目中res/raw中
