  A: needs analysis

1. Functional Description:

Add accounts, query and modify accounts, account information statistics, exit system

1. Design ideas:

(1) new accounts: You can increase the content of the accounts, save the new account information

(2) query and modify: View account information, can be modified audit the accounts, and save the modified information

(3) statistical accounts: Accounts automatic classification of the statistical system for some time, for easy viewing

(4) to exit the system: when you want to shut down the system, you can quickly exit the system

two. Technical Description

Today, technology has improved continuously, people are increasingly high demand for high-tech, on -demand applications on the Android platform more and more. This course is designed primarily to achieve a billing management system to achieve record revenues and record of expenditure and income and expenditure statistics may be this month, and you can log in to register. Use SQLite storage technology income and expenditure information.

登录

 

 

 

２. 原文件

　　

（1）LoginActivity.java:  主要用来进行登录

/**
 * login event
 * @param v
 */
public void OnMyLoginClick(View v){
    if(pubFun.isEmpty(editPhone.getText().toString()) || pubFun.isEmpty(editPwd.getText().toString())){
        Toast.makeText(this, "手机号或密码不能为空！", Toast.LENGTH_SHORT).show();
        return;
    }

    //call DBOpenHelper
    DBOpenHelper helper = new DBOpenHelper(this,"qianbao.db",null,1);
    SQLiteDatabase db = helper.getWritableDatabase();
    Cursor c = db.query("user_tb",null,"userID=? and pwd=?",new String[]{editPhone.getText().toString(),editPwd.getText().toString()},null,null,null);
    if(c!=null && c.getCount() >= 1){
        String[] cols = c.getColumnNames();
        while(c.moveToNext()){
            for(String ColumnName:cols){
                Log.i("info",ColumnName+":"+c.getString(c.getColumnIndex(ColumnName)));
            }
        }
        c.close();
        db.close();

        //将登陆用户信息存储到SharedPreferences中
        SharedPreferences mySharedPreferences= getSharedPreferences("setting",Activity.MODE_PRIVATE); //实例化SharedPreferences对象
        SharedPreferences.Editor editor = mySharedPreferences.edit();//实例化SharedPreferences.Editor对象
        editor.putString("userID", editPhone.getText().toString()); //用putString的方法保存数据
        editor.commit(); //提交当前数据

        this.finish();
    }
    else{
        Toast.makeText(this, "手机号或密码输入错误！", Toast.LENGTH_SHORT).show();
    }
}

 

 

（2）RegistActivity  主要注册成为会员

.java:

/**

 * Description : 注册信息

*/

/**
 * register event
 * @param v
 */
public void OnMyRegistClick(View v)
{
    boolean isTrue = true;
    if(pubFun.isPhoneNumberValid(editPhone.getText().toString()) == false){
        isTrue = false;
        Toast.makeText(this, "手机号格式不正确！", Toast.LENGTH_SHORT).show();
        return;
    }
    if(pubFun.isEmpty(editPwd.getText().toString())){
        isTrue = false;
        Toast.makeText(this, "密码不能为空！", Toast.LENGTH_SHORT).show();
        return;
    }

    if(isTrue = true){
        //call DBOpenHelper
        DBOpenHelper helper = new DBOpenHelper(this,"qianbao.db",null,1);
        SQLiteDatabase db = helper.getWritableDatabase();
        Cursor c = db.query("user_tb",null,"userID=?",new String[]{editPhone.getText().toString()},null,null,null);
        if(c!=null && c.getCount() >= 1){
            Toast.makeText(this, "该用户已存在", Toast.LENGTH_SHORT).show();
            c.close();
        }
        else{
            //insert data
            ContentValues values= new ContentValues();
            values.put("userID",editPhone.getText().toString());
            values.put("pwd",editPwd.getText().toString());
            long rowid = db.insert("user_tb",null,values);

            Toast.makeText(this, "注册成功", Toast.LENGTH_SHORT).show();
            this.finish();
        }
        db.close();
    }else{
        return;
    }
}

 

 

（3）SpendingActivity  记录记账信息添加

.java：

/**

 * Description :记账

*/

String[] titles = new String[]{"明细", "类别报表"};
private static final String[] yearList = {pubFun.getTime("Y") + "年"};
private static final String[] monthList = { "01月", "02月", "03月", "04月", "05月", "06月", "07月", "08月", "09月", "10月", "11月", "12月" };

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //去除工具栏
    getSupportActionBar().hide();
    setContentView(R.layout.spending);

    initViews();

    initSpinner();

    mFragmentAdapter = new FragmentAdapter(this.getSupportFragmentManager(), mFragmentList);
    vp.setOffscreenPageLimit(2);//ViewPager的缓存为2帧
    vp.setAdapter(mFragmentAdapter);
    vp.setCurrentItem(0);//初始设置ViewPager选中第一帧
    item_detail.setTextColor(Color.parseColor("#1ba0e1"));

    //ViewPager的监听事件
    vp.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

        }

        @Override
        public void onPageSelected(int position) {
            /*此方法在页面被选中时调用*/
            //title.setText(titles[position]);
            changeTextColor(position);
        }

        @Override
        public void onPageScrollStateChanged(int state) {
            /*此方法是在状态改变的时候调用，其中arg0这个参数有三种状态（0，1，2）。
            arg0==1的时辰默示正在滑动，
            arg0==2的时辰默示滑动完毕了，
            arg0==0的时辰默示什么都没做。*/
        }
    });

 

 

（4）MainActivity  系统的主界面包括按钮

.java:

/**

四．系统测试：

（1）测试能否添加收入支出

（2）测试能否删除账本信息

（3）测试能否修改金额及账本信息

（4）测试能否查看收入支出情况以及账本信息

 

 

五．系统实现：

（1）登录功能可以实现

（2）添加功能可以实现

（3）删除功能可以实现

（4）修改功能可以实现

（5）查询功能可以实现

 

 

 

 

 

 

六．总结

通过这次课程设计，我明白了原来安卓是一门非常难学难理解的课程，繁琐复杂的代码运行，难懂的安卓语言等困难必须要有非常坚实的基础，有足够的功底才能学好这门课程。目前我是处于一种完全理解不了安卓语言的水平，所以我需要更加进一步的学习这门课程，争取能理解得了一些。
