    今天做了什么?

    在我们的一个小账本的基础上,定制了数据库。有标签,还有具体的金额

     1 package com.example.grouptext02;
     2 
     3 import android.content.Context;
     4 import android.database.sqlite.SQLiteDatabase;
     5 import android.database.sqlite.SQLiteOpenHelper;
     6 import android.util.Log;
     7 
     8 /*
     9  * 
    10  *实现数据库openhelper
    11  *
    12  *
    13 */
    14 public class DataHelper extends SQLiteOpenHelper
    15 {
    16     final static String DATABASENAME = "my_database.db";
    17     final static int    VERSION      = 1;
    18     final static String TABLENAME    = "consumptionInfor";
    19     final static String ID           = "id";
    20     
    21     final static String LABEL        = "label";
    22     final static String MONEY        = "money";
    23     
    24     public static final String TAG = "MY_TAG";//日志
    25     
    26     public DataHelper(Context context)
    27     {
    28         super(context,DATABASENAME,null,VERSION);
    29     }
    30     
    31     
    32     public void onCreate(SQLiteDatabase db)
    33     {
    34         Log.v(TAG,"王大思的标记1.1");
    35         
    36         String sql2 = "CREATE TABLE " +
    37         TABLENAME + "(" +
    38         ID        + " INTEGER PRIMARY KEY AUTOINCREMENT," +
    39         LABEL      + " TEXT," +
    40         MONEY     + " TEXT);";
    41         Log.v(TAG,"王大思的标记1.2");
    42         db.execSQL(sql2);          //创建表
    43         Log.v(TAG,"王大思的标记1.3");
    44     }
    45     
    46     public void onUpgrade(SQLiteDatabase arg0,int arg1,int arg2)
    47     {    
    48         Log.v(TAG,"王大思的标记1.3");
    49     }
    50 }

    这是初期版本,后期预期加入1.备注信息2.消费时间记录

    明天准备做什么?

    进行主页的开发

    遇到的困难!

    final static String DATABASENAME = "my_database.db";
    final static int VERSION = 1;
    final static String TABLENAME = "consumptionInfor";
    final static String ID = "id";

    final static String LABEL = "label";
    final static String MONEY = "money";

    此部分信息,上边数据库类型,还有版本基本不需要改变,后面的一般有id然后,接下来就是定义的数据。
