初學 Android項目 {家庭理財通}

我也是一個初學Android的小白，在校大二項目希望對大家有幫助！

項目文件項目文件中有密碼的Model、Dao、以及創建新密碼的Activity 只不過當時沒有實現。小夥伴們可以在系統設置中自己練習來完善功能
所以登錄時設定了初始密碼
密碼爲 admin 小寫

eclipse	JDK
Android 4.3	JDK1.8

使用 Genymotion 2.12 虛擬器來模擬 Android 手機運行源碼下載

文件樹

AccountTools 爲彈窗工具類使用時直接調用即可

AccountTools.java

代碼片.

package com.ds.accountsoft.tools;
import com.ds.accountsoft.model.InAccount;
import com.ds.accountsoft.model.OutAccount;

import android.content.Context;
import android.view.Gravity;
import android.widget.Toast;
public class AccountTools {
	private Context context;
	public static void showToast(Context context,String text){
		Toast t = Toast.makeText(context, text, Toast.LENGTH_LONG);
		t.setGravity(Gravity.CENTER_HORIZONTAL|Gravity.TOP, 0, 333);
		t.show();
	}
	/**將新Account實例*/
	public static OutAccount checkOut(String str_money,String str_time,String str_type,String str_address,String str_mark){
		OutAccount out = new OutAccount();
		double money = 0 ;
		if(str_money != null && !str_money.equals("")){
			try{
				money = Double.valueOf(str_money).doubleValue();
				out.setMoney(money);
			}catch(Exception e){
				out.setMoney(0);

登錄界面樣式

需要先在strings.xml中添加所需要用到的字段並定義一個name 以便使用下面這是我定義的所有頁面中將使用的文字

strings.xml

弊端軟件如果卸載在重新安裝數據將會消失不會保存

AccountAddOutActivity.java 新增支出

AccountMyAddActivity.java 我的收入

AccountManagerActivity.java 數據管理

AccountFlagActivity.java 收支便籤

還有的頁面也就不放圖了因爲都不盡相同

比如新增支出與新增收入、我的支出與我的收入、還有的
是在數據管理中點擊簡單提示進入，

AccountEditOutActivity(修改新增支出)是回顯到像新增支出一樣的頁面來添加修改與刪除事件
AccountEditInActivity(修改新增收入)與它相同

AccountAddPassword 增加密碼事件未與登錄文本框綁定判斷

系統退出

可執行APK

切記每次修改源碼後執行將需要再次發送安裝來更新
