基于Android的手机订餐系统设计与实现

该系统预计实现的功能有：

话不多说-开搞–先给大家看一下成品：

前言

提示：设计一个基于Android的手机订餐系统。
该系统在Android环境下开发，以Android Studio作为开发工具，使用Java语言作为开发语言，Sql数据库来管理和储存数据。

提示：以下是本篇文章正文内容，下面案例可供参考

一、SQL数据库表的建立。

Android网络存储，用到的是数据库是SQL server

1.建立User.class

public class User {
    private int id;
    private String username;
    private String password;
    private String balance;     //余额
    private String address;
    private String sex;
    private String phone;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getBalance() {
        return balance;
    }

    public void setBalance(String balance) {
        this.balance = balance;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", username='" + username + ''' +
                ", password='" + password + ''' +
                ", balance='" + balance + ''' +
                ", address='" + address + ''' +
                ", sex='" + sex + ''' +
                ", phone='" + phone + ''' +
                '}';
    }

2.建立UserDatabase.class（数据库表建立）

public class UserDatabase extends SQLiteOpenHelper {

    static String name="user.db";

    static int dbVersion=1;
    public UserDatabase(Context context) {
        super(context, name, null, dbVersion);
    }
    //只在创建的时候用一次
    public void onCreate(SQLiteDatabase db) {
        String sql="create table user(id integer primary key autoincrement,username varchar(20),password varchar(20), balance varchar(20),address varchar(20),sex varchar(20),phone varchar(20))";
        db.execSQL(sql);
    }
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

    }
}

3.建立UserService.class(服务端)

public class UserService {
    private UserDatabase dbHelper;

    public UserService(Context context) {
        dbHelper = new UserDatabase(context);
    }

    //登录用
    public boolean login(String username, String password) {
        SQLiteDatabase sdb = dbHelper.getReadableDatabase();
        String sql = "select * from user where username=? and password=?";
        Cursor cursor = sdb.rawQuery(sql, new String[]{username, password});
        if (cursor.moveToFirst() == true) {
            cursor.close();
            return true;
        }
        return false;
    }

    //注册用
    public boolean register(User user) {
        SQLiteDatabase sdb = dbHelper.getReadableDatabase();
        String sql = "insert into user(username,password,balance,address,sex,phone) values(?,?,?,?,?,?)";
        Object obj[] = {user.getUsername(), user.getPassword(), user.getBalance(), user.getAddress(), user.getSex(), user.getPhone()};
        sdb.execSQL(sql, obj);
        return true;
    }
}

二、登录注册页面实现

1.注册页面的实现

代码如下：
里面涉及到地址选择的三级联动，把库添加到build.gradle中

dependencies {
  //城市选择
    implementation 'liji.library.dev:citypickerview:1.1.0'
    }

(1).创建RegistrationActivity

public class RegistrationActivity extends AppCompatActivity {

    @BindView(R.id.text_about)
    TextView textAbout;
    @BindView(R.id.edit_userName)
    EditText editUserName;
    @BindView(R.id.edit_password)
    EditText editPassword;
    @BindView(R.id.edit_phone)
    EditText editPhone;
    @BindView(R.id.edit_address)
    TextView editAddress;
    @BindView(R.id.edit_particular)
    EditText editParticular;
    @BindView(R.id.nan)
    RadioButton nan;
    @BindView(R.id.woman)
    RadioButton woman;
    @BindView(R.id.sexRegister)
    RadioGroup sexRegister;
    @BindView(R.id.btn_register)
    Button btnRegister;
    private CityPicker mCP;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_registration);
        ButterKnife.bind(this);
    }

    @OnClick({R.id.text_about, R.id.btn_register, R.id.edit_address})
    public void onViewClicked(View view) {
        switch (view.getId()) {
            case R.id.text_about:

                break;
            case R.id.btn_register:
                String name = editUserName.getText().toString().trim();
                String pass = editPassword.getText().toString().trim();
                String phone = editPhone.getText().toString().trim();
                String address = editAddress.getText().toString().trim();
                String sexstr = ((RadioButton) RegistrationActivity.this.findViewById(sexRegister.getCheckedRadioButtonId())).getText().toString();
                int num;
                UserDatabase userDatabase = new UserDatabase(this);
                SQLiteDatabase database = userDatabase.getReadableDatabase();
                @SuppressLint("Recycle") Cursor cursor = database.query("user", null, "username=?", new String[]{name}, null, null, null, null);
                num = cursor.getCount();
                if(num >0){
                    Toast.makeText(this,"该账号已被注册,请尝试更换账号注册",Toast.LENGTH_SHORT).show();
                }else {
                    UserService uService = new UserService(RegistrationActivity.this);
                    User user = new User();
                    user.setUsername(name);
                    user.setPassword(pass);
                    user.setPhone(phone);
                    user.setAddress(address + editParticular.getText().toString().trim());
                    user.setSex(sexstr);
                    user.setBalance("0");
                    uService.register(user);
                    Toast.makeText(RegistrationActivity.this, "注册成功", Toast.LENGTH_SHORT).show();
                    Intent intent = new Intent(RegistrationActivity.this, MainActivity.class);
                    startActivity(intent);
                }
                break;
            case R.id.edit_address:
                mYunCityPicher();
                mCP.show();
                break;
        }
    }



    public void mYunCityPicher() {
        //地址选择
        //文字的颜色
        //滑轮文字的颜色
        //省滑轮是否循环显示
        //市滑轮是否循环显示
        //地区（县）滑轮是否循环显示
        //滑轮显示的item个数
        //滑轮item间距
        mCP = new CityPicker.Builder(RegistrationActivity.this)
                .textSize(20)
                //地址选择
                .title("地址选择")
                .backgroundPop(0xa0000000)
                //文字的颜色
                .titleBackgroundColor("#0CB6CA")
                .titleTextColor("#000000")
                .backgroundPop(0xa0000000)
                .confirTextColor("#000000")
                .cancelTextColor("#000000")
                .province("xx省")
                .city("xx市")
                .district("xx区")
                //滑轮文字的颜色
                .textColor(Color.parseColor("#000000"))
                //省滑轮是否循环显示
                .provinceCyclic(true)
                //市滑轮是否循环显示
                .cityCyclic(false)
                //地区（县）滑轮是否循环显示
                .districtCyclic(false)
                //滑轮显示的item个数
                .visibleItemsCount(7)
                //滑轮item间距
                .itemPadding(10)
                .onlyShowProvinceAndCity(false)
                .build();
        //监听
        mCP.setOnCityItemClickListener(new CityPicker.OnCityItemClickListener() {
            @SuppressLint("SetTextI18n")
            @Override
            public void onSelected(String... citySelected) {
                //省
                String province = citySelected[0];
                //市
                String city = citySelected[1];
                //区。县。（两级联动，必须返回空）
                String district = citySelected[2];
                //邮证编码
                String code = citySelected[3];
                editAddress.setText(province + city + district);
            }

            @Override
            public void onCancel() {


            }
        });
    }
}

(2).对应的activity_registration

代码如下（示例）：

总结

这里对文章第一部分的总结：
以上就是今天要讲的内容，本文仅仅简单介绍了SQL数据库的使用，以及用户的登录注册，和制作的一些前期准备工作，下篇文章将写，如何构建RadioGroup控制的滑动页面以及CardView中加载图片文字列表
如下图：
RadioGroup的控制滑动页面

CardView加载图片文字数据

后续还将继续完成订餐系统的实现

最近本人申请公众号，更多Android，demo程序将陆续发布 微信搜索：毕设服务中心，获取更多信息

最后

以上就是动人世界为你收集整理的基于Android的手机订餐系统设计与实现（一）基于Android的手机订餐系统设计与实现前言一、SQL数据库表的建立。二、登录注册页面实现总结的全部内容，希望文章能够帮你解决基于Android的手机订餐系统设计与实现（一）基于Android的手机订餐系统设计与实现前言一、SQL数据库表的建立。二、登录注册页面实现总结所遇到的程序开发问题。
