Android课设——理财小助手_安卓课设

一：app介绍
理财小助手是一款利用Android studio软件实现的APP，可以录入每天的消费项目以及消费金额，同时也可以查找消费记录、统计消费总额。我用到的Android studio版本如下：
二、模块设计
下面是我实现的一些模块：
1：进入理财小助手app时会有一个登陆界面，包括邮箱和密码，邮箱和密码都有限制，如邮箱必须带有@符号，而密码必须不少于特定位数。

2：如果没有登录的邮箱或者密码时选择注册账号：

3：进入理财app先进入理财记录的首页：（此时还没有添加一条记录，首页显示为空）

4：添加一条消费记录，消费主体是lunch，消费金额是12，消费感受是good

5：点击左上方的箭头会默认自动保存此记录，如果点击右上方的X，就会删去这条记录，这样，在理财app的主页就会显示添加的消费记录：

6：也可以双击每一条记录，这样就会出现此记录的详细信息，比如我选择了第一条记录：

7：查看第五个步骤可以发现第五个步骤的图像右上方有三个符号，第一个+符号是添加一条记录，第二个符号是查找消息记录，第三个符号是可以统计金钱总额也可以显示出所有的消费记录：
第一个符号：

第二个符号查找记录：

第三符号有两个功能：

（1）：统计功能：

比如统计今天记录：2022年1月15日

（2）显示记录的条数：如下，显示了添加的两条记录

三、代码设计
此代码设计分为两个部分，一个为前端的局面分布，一个为后端的java编写。如下：

1：java文件夹里面包含的是后端的代码，其中包含了database和wengxiaoyang.personalfinanceassistant。其中包括的类如下图所示：

2：res文件夹里面包括的是图片和前端代码，包括button或者布局等，是安卓必须掌握的基础知识点。

其中可可爱爱的蜡笔小新就来自与drawable，当然也可以换成其他的图片啦。在这里插入图片描述

layout里面存放的就是整个app的布局：

menu用来控制右上方的三个符号功能：

values用来控制button按钮：

注意：其他没有特别说明就是图片。

四、详细代码
1：先贴入java后端的代码
database中的ManageBaseHelp类

package database;
//数据库的继承类，并重写两种方法
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

import database.ManageDbSchema.ManageTable;

//打开数据库
public class ManageBaseHelper extends SQLiteOpenHelper {
    private static final int VERSION = 1;
    private static final String DATABASE_NAME = "manageBase.db";
//在此构造方法中用super方法调用父类的构造方法。传入四个参数，上下文对象，数据库名称，null，数据库版本
    public ManageBaseHelper(Context context) {
        super(context, DATABASE_NAME, null, VERSION);
    }

//重写子类的onCreate方法
    @Override
    public void onCreate(SQLiteDatabase db) {
        // manage表，暴力名称，金钱，支付方式等
        db.execSQL("create table " + ManageTable.NAME + "(" +
                "_id integer primary key autoincrement, " +
                ManageTable.Cols.UUID + ", " +

                ManageTable.Cols.PAYMETHOD  + ", " +
                ManageTable.Cols.REMARK + ")"
        );
        // 账号密码表
        db.execSQL("create table " + ManageTable2.NAME2 + "(" +
                "_id integer primary key autoincrement, " +
                ManageTable2.Cols2.UUID + ", " +
                ManageTable2.Cols2.ACCOUNT + ", " +
                ManageTable2.Cols2.PASSWORD + ")"
        );
    }
    //重写子类的onUpgrade方法
    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

    }
}

//获得manage和login表格填写时的信息，并把他们放入数据库里面
public class ManageCursorWrapper extends CursorWrapper {

    }

    public Manage getManage() {
