磕磕绊绊的写了第一个程序，电脑报价单。工作需要，经常做些报价单，所有就有了这个小程序。虽然能运行了，但其中的一些代码不甚了解，在这里做个学习总结。
基本界面。
用到SQLite数据库
package com.example.diyquote;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteDatabase.CursorFactory;
import android.database.sqlite.SQLiteOpenHelper;
public class MySQLiteOpenHelper extends SQLiteOpenHelper
{
// 定义数据库的版本
public static final int DB_VERSION = 1;
// 定义数据库的名字
public static final String DB_NAME = "mydata.db";
public MySQLiteOpenHelper(Context context, String name, CursorFactory factory, int version)
{
super(context, name, factory, version);
}
@Override
public void onCreate(SQLiteDatabase db)
{
db.execSQL(StrName.STR_MAIN_LIST); //StrName为另外定义的包含全部需要用的常量的类，以方便使用。这个是建立首页ListView需要的数据库，用来存储客户和渠道信息
db.execSQL(StrName.DETAILED_TEABLE);//另外的表，存储所有的配件的报价。
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)
{
}
}
定义了一个需要常用的常量的类StrName，方便使用
package com.example.diyquote;
import java.text.SimpleDateFormat;
import java.util.Date;
public class StrName
{
public static final String TEABLE_NAME_MAINLIST="mainlist"; //用来存储客户和渠道信息的表的名字
public static final String TABLE_NAME_DETAILED="detailed"; //存储 配件信息价格之类的表的名字。
public static final String DETAILED_TEABLE= "create table detailed (" //建立表
+" _id integer primary key autoincrement," //_id字段，ListView需要
+" imgsrc text," //配件的IMG,并未使用
+" peijian text," //配件的名字，CPU，主板，显卡 之类
+" xinghao text," //配件的型号
+" baojia integer," //报价
+" jinjia integer," //进价
+" shuliang integer," //数量
+" lirun integer," //利润
+" xiaoji integer," //利润小计
+" mainid integer)"; //maiId，与mainlist表中的_id对应，每个客户和渠道信息对应一个mainlist中的_id，也就是这里的mainid
public static final String STR_MAIN_LIST="create table mainlist (" //建表
+" _id integer primary key autoincrement," //_id字段
+" textlist text," //客户和渠道信息
+" date text)"; //存储时的日期
public static String getDate() //获取系统日期时间
{
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm");
Date curDate = new Date(System.currentTimeMillis());
String date = formatter.format(curDate);
return date;
}
