今天我实现连接数据库并且输入日常收入，日常支出的功能。

(1)连接数据库

package com.example.feigou.db;

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteException;

public class ComeModle {

    MyDBHelper dbHelper;
    SQLiteDatabase sqlite;
    
    public ComeModle(Context context) {
        dbHelper=new MyDBHelper(context,"jizhang.db",null,2);
        
        try {
            //打开数据库
            sqlite=dbHelper.getWritableDatabase();
        }catch(Exception e) {
            sqlite=dbHelper.getReadableDatabase();
        }
        
        
        
    }
    
    
    //保存数据
    public boolean save(String string,String money,String sStyle,String sFenlei,String strTime,String note) {
        try {
            String insertSQL = "insert into come(inorout,money,style,fenlei,time,note) values(?,?,?,?,?,?)";
            sqlite.execSQL(insertSQL, new Object[] { string, money, sStyle, sFenlei, strTime, note });
            return true;
        } catch (SQLiteException e) {
            e.printStackTrace();
            return false;
        }
    }
    
}

package com.example.feigou.db;

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteException;

public class ComeModle {

    MyDBHelper dbHelper;
    SQLiteDatabase sqlite;
    
    public ComeModle(Context context) {
        dbHelper=new MyDBHelper(context,"jizhang.db",null,2);
        
        try {
            //打开数据库
            sqlite=dbHelper.getWritableDatabase();
        }catch(Exception e) {
            sqlite=dbHelper.getReadableDatabase();
        }
        
        
        
    }
    
    
    //保存数据
    public boolean save(String string,String money,String sStyle,String sFenlei,String strTime,String note) {
        try {
            String insertSQL = "insert into come(inorout,money,style,fenlei,time,note) values(?,?,?,?,?,?)";
            sqlite.execSQL(insertSQL, new Object[] { string, money, sStyle, sFenlei, strTime, note });
            return true;
        } catch (SQLiteException e) {
            e.printStackTrace();
            return false;
        }
    }
    
}

(2)日常收入，输入收入金额，收入方式，收入分类，收入时间，收入备注。然后把信息存储到数据库中。
