Android 练习项目 ——简单记账软件的实现

一、需求分析

在我们生活中经常不知道钱花在什么地方，但是我们自己又不是很想写在记账本上进行管理，由于智能手机的兴起，手机离我们越来越近，导致我们生活时时刻刻都有手机的存在，所以说手机的操作离我们越来越近，趋势越来越明显。但是对于记账，我们往往每个人都有自己的需求，所以对于自己来说，开发一个简单的软件来记账是个非常好玩且有趣的事情。
所以自己趁着学习Android开发的机会，顺便做一个练习项目，本人小白，一开始啥都不懂，但是我有一颗不断学习的心，相信只要自己努力，怎能够作出自己的事业。
我就简单的分析自己需求，对于衣食住行进行分类，然后记录每天的时间，记录下消费的原因，最为重要的就是金额了。总会做个账单统计，分析自己当前的支出和收入，离预算还有多少钱花费。

二、设计界面

账户界面：

记账界面：

功能区界面：

账单显示界面：

补充：功能区实现的功能目前有：记一笔，账单，导出数据，同步数据，其他功能待实现，其实我本人还想做个计一划的实现，实现记账和日常安排计划同时实现。

三、程序设计

由于高仿微信的界面的实现，所有用了Fragment的布局，滑动切换界面，点击功能区按钮来实现对应功能的添加。
这里面用到的技术主要有ListView，Fragment+viewpage,Activity,sqlite数据库技术，还有Post传参来实现同步服务器端的数据。由于服务端框架接触的少，所以功能只有同步数据。同步数据用到了service实现和操作excel技术。

四、代码实现

首先介绍主界面的实现：Fragment+activity布局
MainActivity.java

package com.bank;import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v4.view.ViewPager.OnPageChangeListener;
import android.view.View;
import android.widget.ImageButton;
import android.widget.LinearLayout;import java.util.ArrayList;
import java.util.List;public class MainActivity extends FragmentActivity implements View.OnClickListener {private View.OnClickListener onclicklistene;private ViewPager mViewPager;private FragmentPagerAdapter mAdapter;private List<Fragment> mFragments = new ArrayList<Fragment>();/*** 底部四个按钮*/private LinearLayout mTabBtnWeixin;private LinearLayout mTabBtnFrd;private LinearLayout mTabBtnAddress;private LinearLayout mTabBtnSettings;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mViewPager = (ViewPager) findViewById(R.id.id_viewpager);initView();findViewById(R.id.btn_tab_bottom_weixin).setOnClickListener(this);findViewById(R.id.btn_tab_bottom_contact).setOnClickListener(this);findViewById(R.id.btn_tab_bottom_friend).setOnClickListener(this);findViewById(R.id.btn_tab_bottom_setting).setOnClickListener(this);mAdapter = new FragmentPagerAdapter(getSupportFragmentManager()) {@Overridepublic int getCount() {return mFragments.size();}@Overridepublic Fragment getItem(int arg0) {return mFragments.get(arg0);}};mViewPager.setAdapter(mAdapter);mViewPager.addOnPageChangeListener(new OnPageChangeListener() {private int currentIndex;@Overridepublic void onPageSelected(int position) {resetTabBtn();switch (position) {case 0:((ImageButton) mTabBtnWeixin.findViewById(R.id.btn_tab_bottom_weixin)).setImageResource(R.drawable.tab_weixin_pressed);break;case 1:((ImageButton) mTabBtnFrd.findViewById(R.id.btn_tab_bottom_friend)).setImageResource(R.drawable.tab_find_frd_pressed);break;case 2:((ImageButton) mTabBtnAddress.findViewById(R.id.btn_tab_bottom_contact)).setImageResource(R.drawable.tab_address_pressed);break;case 3:((ImageButton) mTabBtnSettings.findViewById(R.id.btn_tab_bottom_setting)).setImageResource(R.drawable.tab_settings_pressed);break;}currentIndex = position;}@Overridepublic void onPageScrolled(int arg0, float arg1, int arg2) {}@Overridepublic void onPageScrollStateChanged(int arg0) {}});}protected void resetTabBtn() {((ImageButton) mTabBtnWeixin.findViewById(R.id.btn_tab_bottom_weixin)).setImageResource(R.drawable.tab_weixin_normal);((ImageButton) mTabBtnFrd.findViewById(R.id.btn_tab_bottom_friend)).setImageResource(R.drawable.tab_find_frd_normal);((ImageButton) mTabBtnAddress.findViewById(R.id.btn_tab_bottom_contact)).setImageResource(R.drawable.tab_address_normal);((ImageButton) mTabBtnSettings.findViewById(R.id.btn_tab_bottom_setting)).setImageResource(R.drawable.tab_settings_normal);}private void initView() {mTabBtnWeixin = (LinearLayout) findViewById(R.id.id_tab_bottom_weixin);mTabBtnFrd = (LinearLayout) findViewById(R.id.id_tab_bottom_friend);mTabBtnAddress = (LinearLayout) findViewById(R.id.id_tab_bottom_contact);mTabBtnSettings = (LinearLayout) findViewById(R.id.id_tab_bottom_setting);FragmentAccount fragmentaccount = new FragmentAccount();FragmentFind fragmentfind = new FragmentFind();FragmentPlan fragmentplan = new FragmentPlan();//        MainTab02 tab02 = new MainTab02();//      FragmentBills fragmentbills = new FragmentBills();MainTab04 tab04 = new MainTab04();mFragments.add(fragmentaccount);mFragments.add(fragmentplan);mFragments.add(fragmentfind);mFragments.add(tab04);}public void onClick(View v) {switch (v.getId()) {case R.id.btn_tab_bottom_weixin:mViewPager.setCurrentItem(0, true);break;case R.id.btn_tab_bottom_friend:mViewPager.setCurrentItem(1, true);break;case R.id.btn_tab_bottom_contact:mViewPager.setCurrentItem(2, true);break;case R.id.btn_tab_bottom_setting:mViewPager.setCurrentItem(3, true);break;}}
}

接下来就是Fragment的实现，我一开始测试中用了4个Fragment来实现，由于有些还需要添加新的功能，所以第一版还是有些挫和部分功能还没有实现。

FragmentAccount.java

package com.bank;import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.support.v4.app.Fragment;

import android.view.View;

import android.widget.TextView;import java.text.DecimalFormat;public class FragmentAccount extends Fragment {private MySQLiteHelper mMysql;private SQLiteDatabase mDataBase;private TextView textRemainder,textPay,textIncome;@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {View view = inflater.inflate(R.layout.finance_check, container, false);double resultIncome = 0,resultRemainder = 0,resultPay = 0;textIncome      = (TextView)view.findViewById(R.id.textincome);textRemainder      = (TextView)view.findViewById(R.id.textremainder);textPay      = (TextView)view.findViewById(R.id.textpay);mMysql = new MySQLiteHelper(getActivity(), "finance.db", null, 1);mDataBase = mMysql.getReadableDatabase();//   String sql      = "select Fee from finance where Budget='支出'";//Cursor cursor = mDataBase.query("finance", null, null, null, null, null, null);//  Cursor cursor = mDataBase.query("finance", new String[]{"Fee"},"where Budget=?",new String[]{"支出"},null,null,null);
// String sql      ="insert into finance('Type','Time','Fee','Remarks','Budget') values('衣','20160330',37.6,'买衣服','支出')";
//                int i =0;
//                while( i<20)
//                {
//                        mDataBase.execSQL(sql);
//                        i++;
//                }Cursor cursor = mDataBase.rawQuery("select Fee,Budget from finance",null);cursor.moveToFirst();if (cursor.getCount() > 0) {for (int i = 0; i < cursor.getCount(); i++) {//  cursor.move(i);//移动到指定记录double Fee = cursor.getDouble(cursor.getColumnIndex("Fee"));String budget = cursor.getString(cursor.getColumnIndex("Budget"));if(budget.equals("支出")) {resultPay += Fee;} else if (budget.equals("收入")){resultIncome += Fee;}cursor.moveToNext();}}DecimalFormat df = new DecimalFormat("###.##");textPay.setText(String.valueOf(df.format(resultPay)));textIncome.setText(String.valueOf(df.format(resultIncome)));textRemainder.setText(String.valueOf(df.format(resultIncome - resultPay)));cursor.close();mDataBase.close();mMysql.close();return view;}
}

}

目前完成的主要是这两个界面的功能。

现在介绍下关于记账界面代码：
BillsActivity.java，主要从数据库获得数据，并通过listview显示。常按能够删除账单条目。

MySQLiteHelper.java 数据库操作的辅助类。

SubmitDataService.java
主要是同步数据的时候需要用到的服务。

package com.bank;import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;

}

还有服务端代码也给出来，通过操作xml文件来传递数据。
finance.php

<?php$file_in = file_get_contents("php://input");$xml=simplexml_load_string($file_in); ini_set("display_errors", "On");error_reporting(E_ALL | E_STRICT);   $Type ="食";$Time ="2015-02-01";$ID =3;$connection    =mysql_connect("localhost","zhouchenglin","zhouchenglin");if(!$connection){die("不能连接数据库:".mysql_error());} else{echo "连接成功";}if(!mysql_select_db("zhouchenglin",$connection)) {die("Select Database Failed: " . mysql_error($connection));    }else{echo "数据库连接成功";}mysql_query("set names utf8");$sql =sprintf("INSERT INTO `finance`(`ID`,`Type`, `Time`,`Fee`,`Remarks`,`Budget`)VALUES('%d', '%s','%s','%f','%s','%s')",$xml->ID,$xml->Type,$xml->Time,$xml->Fee,$xml->Remarks,$xml->Budget);$res =mysql_query($sql,$connection);if(!$res){            die(mysql_error());         echo '执行失败';}elseecho '执行成功';mysql_close($connection);?>

主要的功能都是通过这些代码实现。我就粘贴几个重要的布局文件。

主要功能和实现就是这些，希望自己中涉及到的技术以后自己能够用得到。通过观看以前写过的代码来反映自己的成长，这是一个多么令人兴奋的故事。
